The purpose of this study was to compare the circumference, skinfold thickness and strength of the normal and casted lower limb prior to casting and following removal of the cast. The subjects for the study were nine orthopedic patients who had had long and short leg casts due to a tibial, fibula, or calcaneus fracture, or to a lateral collateral ligament rupture. Circumference, skinfold thickness, and strength of the normal and casted lower limb following removal of the cast were compared with those prior to the application of the cast. Measurements were made before cast application and after removal of the cast. Skinfold thickness was measured by fat caliper, circumference was measured by tape and strength was determined by measuring the length of time the leg was held elevated at 45. The results can be summarized as follows: 1. There was no change in the normal limb in the circumference of the midthigh and midcalf after casting as compared to before cast application. 2. In the casted limb the circumference of the midthigh decreased by 3.23% and that of the midcalf decreased significantly by 7.49% during the period of casting. 3. In the normal limb skinfold thickness of the quadriceps decreased and that of gastrocnemius increased by 20.63% during the period of cast application. 4. In the casted limb skinfold thickness of the quadriceps decreased significantly by 12.37% and that of gastrocnemius decreased by 10% during the period of cast application. 5. Strength of the normal lower extremity decreased significantly by 48.37% and that of casted lower extremity decreased remarkably by 73.07% during the period of cast application. 6. Circumference of the midthigh and the midcalf decreased significantly by 7.6% and 9.4% respectively on the casted side as compared to the normal side. Skinfold thickness of the quadriceps and the gastrocnemius on the casted side decreased by 6.12% and 18.55% respectively as compared to the normal side and strength in the lower extremity on the casted side decreased significantly by 44.32% as compared to the normal side. From these results, it may be concluded that muscle atrophy occurs in the casted lower limb and muscle strength of the normal lower limb are also reduced during the period of application of a leg cast.

Inpatients are mostly occupied in bed with restric ted activity, nearly all patient populations are at risk for the occurrence of skeletal muscle atrophy due to decreased level of activity. Restriction of mobility is far greater in pediatric patients compared with adult patients since almost all the activities of daily living is performed by parents or caregivers. It could be assumed that pediatric patients are more vulnerable to skeletal muscle atrophy than adult patients, however, there have been no attempts to reduce the atrophy of developing muscle. Therefore it is important to determine the effect of exercise in developing muscle during decreased activity. The purpose of this study was to determine the effect of periodic weight support during hindlimb suspension on the mass and cross-sectional area of Type I. and II fibers in developing soleus (Type I) muscle. To examine the effectiveness of periodic weight support activity in maintaining mass and fiber size, the hindlimb of young female Wistar rats was sus-pended(HS) and half of these rats walked on a treadmill for 45min/day(15min every 4h) at 5m/min at a 15 grade (HS-WS). After 7days of hindlimb suspension, soleus wet weight was 28. 57% smaller and relative soleus weight was 28. 21% smaller in comparison with con trol rats (p<0.05) Soleus wet weight and relative soleus weight increased by 67.72% and 71.43% each with periodic weight support activity during hindlimb suspension (p(0.01. p<0.005), moreover soleus wet weight and relative soleus weight of the HS-WS rats were greater than those of the control group. No change was observed in fiber type percentage of the developing soleus muscle after 1 week of hindlimb suspension plus weight support activity. Type I and II fiber cross-sectional areas of the developing soleus muscle were 50.45% and 43.39% lower in the HS group than in the control group (p<0.0001), type I and II fiber cross-sectional areas of the developing soleus were 24.49% and 29.93% greater in the HS-WS group than in the HS rats (p<0.0001), whereas Type 1 and II fiber cross-sectional areas of HS-WS group were less than those of the control group. The results suggest that periodic weight support activity can ameliorate developing soleus muscle atrophy induced by hindlimb suspension, even in type II fibers that would not have been expected to be recruited by this type of neuromuscular demand. Clinical experimental study is needed to determine the effect of periodic weight bearing exercise on developing atrophied leg muscle based on these results.

The purpose of this study was to compare the circumference and skinfold thickness of upper and lower limb and the leg strength of the casted limb with those of the normal limb after removal of a leg cast. The subjects for the study were orthopedic patients who had had long and short leg casts or splints due to tibial, fibulal, metatarsal, calcaneus fracture or ankle sprains. The subjects were divided into two groups, those who had the cast on for less than 40 days and those for over 41 days. Circumference and skinfold thickness of the upper and lower limb on the side on which the cast was applied were compared with those of the contralateral side after removal of the cast. Circumference and skinfold thickness of the upper and lower limb, and leg strength for those in a cast for under 40 days were compared with those of over 41 days for both the side to which cast was applied and the contralateral side. Measurements were made after removal of the cast. Skinfold thickness was measured by fat cali-per, circumference was measured by tape and lower extremity strength was determined with flat foot pressing on an electronic digital health meter in the sitting position. The results can be summarized as follows; 1. The circumference of the upper and lower leg on the side on which the cast was applied, when measured after the cast was removed, were significantly less than those of the normal side, 93.88%, 93.11% each. 2. Skinfold thickness of the quadriceps and gastrocnemius on the side on which the cast was applied were significantly less than those of the normal side when measured after removal of the cast, 85.98%, 82.85% respectively. 3. Leg strength on the side where the cast was applied was significantly lss than that on the normal side, 60.20%. 4. There was no difference in the circumference of upper and lower limbs, skinfold thickness or leg strength on the side where the cast was applied between the group which had the cast applied for under 40 days and the group that had it applied for over 41 days. 5. The circumference of the upper arm and lower leg on the normal side for the group that had the cast applied for over 41 days was significantly greater than the group that had the cast application for under 40 days. There was no difference between the two groups in the circumference of the forearm and upper leg, skinfold thickness and leg strength in the normal side, from these results, it may be concluded that muscle atrophy was apparent in the casted limb compared to the normal limb, and the circumference of the upper arm and lower leg, and leg strength on the normal side increased after removal of the cast in the group which had the cast on for more than 41 days.

The purpose of this study was to determine the effect of exercise training on the length and circumference of atrophied muscles to see whether improvement in restoring the atrophied muscle mass, of either length or circumference growth could be induced through exercise training. Adult female Wistar rats maintained for 14 days with hindlimb suspension. Rats were then assigned randomly to a sedentary group or training group. The length and circumference of both atrophied soleus and plantaris muscle for the training and sedentary groups following hindlimb suspension were compared with those of a control group. Length and circumference of both atrophied soleus and plantaris muscle in trained group was compared with those in the sedentary group. The results can be summarized as follows ; 1) Atrophy of soleus and plantaris muscle was induced with hindlimb suspension. 2) The circumference of both the soleus and plantaris muscle following hindlimb suspension was reduced to 51.72%, 66.67% respectively compared to the control group. The length of both the soleus and plantaris muscle following hindlimb suspension did not show any difference compared to the control group. 3) There was no difference in length for either the atrophied soleus or plantaris muscle between the trained and the sedentary group during recovery from hindlimb suspension. 4) The circumference of both the atrophied soleus and plantaris muscle did not return to normal in the sedentary group, however, the circumference of both the atrophied soleus and pantaris muscle were significantly greater than of the control in the trained group, 14.22% and 9.38% respectively 5) The circumference of both the atrophied soleus and plantaris muscle in the trained group was significantly larger than that of both muscles in the sedentary group at day 28 of recovery. From these results, it can be suggested that improvement in restoring the atrophied muscle mass through exercise training might be induced by growth of the muscle circumference.

The purpose of this study was to determine the amount of soleus muscle atrophy in rats due to 28 days of decreased activity induced by hindlimb suspension, to observe the restoration of mass and relative muscle weight of the atrophied soleus muscle at day 28 of recovery to control value, and to compare the effect of run training on the mass and relative muscle weight of the atrophied soleus muscle at day 28 of recovery with that of sedentary rats. Adult female Wistar rats were maintained for 28 days with hindlimb suspension. Rats were then assigned randomly to a cage sedentary or running group. Soleus muscle mass and relative muscle group. Soleus muscle mass and relative muscle weight following hindlimb suspension were compared with a control value. The muscle mass and relative muscle weight of the running and cage sedentary groups following hindlimb suspension were compared with those of a control group. Soleus muscle mass and relative muscle weight of the run training group were compared with those of cage sedentary group. The results obtained were as follows : 1. Soleus muscle mass and relative muscle weight was reduced to 53.28% and 51.11% respectively by hindlimb suspension. 2. Soleus muscle mass and relative muscle weight of the training group day 28 of recovery was restored to the control value. 3. Soleus muscle mass of the training group was greater than that of the cage sedentary group by 6.6% without statistical significance at day 28 of recovery. 4. Relative soleus muscle weight of the training group was significantly greater than that of the cage sedentary group by 15.79%. From these results, it may be concluded that run training during the posthypokinetic period facilitates the recovery of the atrophied soleus muscle mass of rats.

This study investigated the effect of changing position from supine to standing upright on the circulation of young men and women. Healthy men and women ranging from age of 18 to 24 were examined. Two minutes before standing, the baseline heart rate and blood pressure were measured. Heart rate and blood pressure were recorded immediately and at every minute for 10 minutes after standing upright. Differences in heart rate and blood pressure between supine and standing upright position were evaluated. The results were summarized as follows: 1. Heart rate increased significantly immediately and at every minute for 10 minutes after standing upright. 2. Systolic blood pressure increased significntly immediately and at every minute for 4 minutes after standing upright. 3. Diastolic and mean blood pressure increased significantly immediately and at every minute for 10 minutes after standing upright. 4. Pulse pressure immediately and at every minute for 10 minutes after standing upright was significantly narrower than that of supine position. 5. There was no significant difference of heart rate between men and women after standing upright. 6. Systolic and diastolic blood pressure of men after standing upright was significantly greater than those of women. From these results, it may be concluded that heart rate, systolic, diastolic and mean blood pressure and pulse pressure increase after standing upright, and systolic and diastohc blood pressure in men is greater than those of women after standing upright.

To evaluate training effect, aerobic dance was performed by eight female collegestudents for 8 weeks.' Body composition, cardiopulmonary function at rest and during maximal exercise, blood cholesterol concentration at rest were determined before and after 8weeks of aerobic dance training. Maximal exercise was performed on the treadmill according of Bruce protocol. Pre to post training differences were evaluated. The results obtained were as follows: 1. After the training, skinfold thickness and total body fat decreased significantly(p<0.1) while lean body mass increased with significance (p<0.1). 2. Heart rate and arterial blood pressure at rest decreased without sinificance after the training. 3. As a result of training, forced vital capacity and forced expiratory volume for a second increased significantly (p<0.01, P<0.1). 4. After the training period, heart rate at 3,6, and 9 min. during treadmill exercise was significantly lower than those of pretraining (p<0.05). 5. After the training, systolic and diastolic blood pressure at 6 and 9 min during the exercise was significantly lower than those of pretrainirig (p<0.025, p<0.1). 6. After the training, oxygen uptake at 3 and 6 min . during the exercise was significantly greater than those of pretraining (p<0.05). 7. As a result of training, the maximal oxygen uptake increased significantly during the exercise (p<0.1). 8. After the training, expired air volume for a minute at 3 and 6 min during the exercise was signigicantly grerter than those of pretraining (p<0.1). 9. After the training, repiratory quotient during the exercise was lower than pretaining without signif icance. 10. After the training, blood HDL-cholesterol concentration incereased with significance, (p<0.1) blood total cholesterol and triglycerids concentration dec-reasedsigntficantly (p<0.1). From these results, it may be concluded that 8 week aerobic dance training reduces skinfold thickness and body fat contents, improves the cardiopulmonary function and tissue oxygen utilization, reduces blood cholesterol and triglyceride concentration and brings about the increase of blood HDL-cholesterol concentriation.

The present study has been undertaken to assess the electrical activity of right tibialis anterior, right gastroc-nemius, right rectus femoris, right biceps femoris and right paralumbarvertebral muscles quantitatively by EMC while standing erect on the height of 0cm, 3cm, 5cm and 7cm heels. The inclinations of the heels were 0, 6, 11, 17 degrees, respectively. Fourty young women ranging from 18 to 24 of age were examined. Electrical activity of various muscles while standing erect on the height of various heels were compared with that of 0cm heel. The results obtained were as follows: 1. Electrical activity of the tibialis anterior increased significantly as the height of heels became higher ; which was thought to be due to the effort to counteract the instability standing with high heels. 2. There was a significant increase in electrical activity of the gastrocnemius as the height of heels increased. It might be due to compensatory activity against shifting of the center of gravity forward. 3. There was a significant increase.in electrical activity of the rectus femoris and biceps femoris at the height of 3cm, 5cm and 7cm heels ; which seemed to be due to the effort to stabilize the knee joint. 4. Electrical activity of the paralumbarvertebral muscles increased significantly at the height of 5cm and 7cm heels : which was considered to be due to the effort to prevent forward imbalance. From These results, it may be concluded that electrical activities of vanous postural muscles increase significantly while standing erect on the height of 3cm, 5cm and 7cm heels to counteract an instability of their posture and compensate the forward shifting tendency of the center of gravity.

This study was undertaken to elucidate effects of ingesting small or large amount of tap or iced water on circulation of normal healthy men with the purpose of furnishing basic data for nursing interven-tion of myocardial infarction patients. The subjects for this study were normal healthy men consisting of 30men and 30women in age from 22 to 30 years. One group consisting of 30men drank 240ml tap water on dayl and 240ml iced water 24hours later. The other group drank 960ml tap water on day 1 and 660ml iced water 24hours later. Blood pressure and heart rate were taken in a sitting position before ingesting water, and immediately after ingesting it and at 2,5,10,15,30 minute intervals thereafter. Changes of heart rate, systolic and diastolic blood pressure after ingesting water were compared with those of preingestive period. The results obtained were as follows: 1. There were no significant changes in blood pressure and heart rater after ingesting small amount of water regardless of its temperature. 2. No significant decrease in blood pressure after ingesting large amount of tap water at all time peroids was noted. 3. A strongly significant interaction effect between temperature and volume was demonstrated, that is, there was a highly significant decrease in blood pressure and heart rate at all time periods after ingesting large amount of iced water.

As patients on bed rest perform repeated Valsalva. maneuver, it is necessary for them to prevent thedanger inherent in repeated Valsalva maneuver through intelligent rehabilitative nursing care. In this regard, it seems to be important to furnish a scientific rationale underlying rehabilitative nursing care. This study was undertaken to find the effects of repeated Valsalva maneuver upon circulation of normal men. The subjects for this study were twenty normal and healthy college students of age from 19 to 26. For the first time, the ECG of standard 12 leads was recorded and the blood pressure was measured under the resting state. And the subjects performed Valsalva maneuver for 10 seconds, then expired air for 2 seconds. After the subjects carried out in this manner for 1 minute, the ECG and the blood pressure were recorded and measured again. The Changes of heartbeats, systolic and diastolic pressures after the practice of repeated Valsalva maneuver were compared with those of the resting state. The results obtained were as follows: 1. The heartbeats after the practice of repeated Valsalva maneuver generally increased but did not show statistical significance. 2. The systolic pressure measured after the practice of repeated Valsalva maneuver was higher than that of the resting state. 3. The diastolic pressure measured after the practice of repeated Valsalva maneuver was higher than that of the resting state.

The purpose of this study was to determine the effect of regular exercise during dexamethasone injection on the body weight, weight of hindlimb muscles and adrenal gland in young rats. 80-100g Wistar rats were divided into control, exercise, dexamethasone injection(dexa), and exercise during dexamethasone injection(D+E) group. The dexa group received daily subcutaneous injection of dexamethasone at a dose of 5mg/kg body weight for 10 days. The exercise group ran on a treadmill for 60min/ day(20 minutes every 4 hour at 10m/ min and a 10degrees grade. The control group received daily subcutaneous injection of normal saline at a dose of 5mg/kg body weight for 10 days. The D+E group ran on a treadmill for 60min/day(20 minutes every 4hour) at 10m/min and a 10degrees grade. Body weight of both control and exercise group increased significantly until 10 days, the of both dexa and D+E group decreased significantly, resulting in 79.47 and 78.75% decrease respectively compared to the first day of experiment. Body weight and muscle weight of the soleus, plantaris and gastrocnemius decreased significantly with dexamethasone injection. Relative weight of the dexa group decreased significantly compared to that of the control group. Body weight and muscle weight of the soleus and plantaris of the D+E group showed a tendency to increase, and muscle weight of the gastrocnemius increased significantly compared to the dexa group. The Relative weight of the plantaris was comparable to the control group and that of the soleus and gastrocnemius tended to increase, in the exercise group. Body weight and muscle weight of the soleus and plantaris of the D+E group showed a tendency to increase, and muscle weight of the gastrocnemius increased significantly compared to the dexa group, The Relative weight of the soleus and gastrocnemius tended to increased and that of the plantaris of the D+E group increased significantly compared to the dexa group. Body weight, muscle weight and relative weight of the soleus, plantaris and gastrocnemius of the D+E group increased significantly compared to the dexa group Adrenal gland weight of the dexa and D+E group tended to increase, and that of the exercise group increased significantly. From these results. it can be suggested that regular exercise during dexamethasone injection might attenuate the decrease of body weight and hindllimb muscle weight induced by the dexamethasone injection.

The purpose of this study was to determine the effect of endurance training prior to occurrence of muscle atrophy on the mass, myofibrillar protein content and fiber crossectional area of atrophied hindlimb muscles of rats. Adult female Wistar rats were trained prior to occurrence of muscle atrophy induced by hindlimb suspension. Training began on the lst day for 10min/day at 15m/min on a 0% grade, training exercise increased daily in time and intensity so that by the 4th week rats were running 60min/day, at 34m/min on a 13.5% grade. Wet weight and relative weight of soleus, plantaris and gastrocnemius muscle decreased significantly after seven days of hindlimb suspension. Wet weight and relative weight of soleus tended to increase and that of plantaris and gastrocnemius tended to decrease in the exercise group as compared to the control group. Myofibrillar protein content of soleus and gastrocnemius tended to in crease and that of plantaris tended to decrease in the endurance trained group as compared to the control group. Fiber crossectional area of Type I, II fiber in soleus and plantaris muscle tended to increase in the exercise group as compared to the control group. Wet weight and relative weight of soleus, plantaris and gastrocnemius decreased significantly, myofibrillar protein content of soleus, plantaris and gastrocnemius increased in hindlimb suspended rats following endurance training as compared to the control group. There was no change in fiber type percentage and crossectional area of type I and II fiber in soleus muscle and that of type I and II fiber in plantaris muscle decreased in the hindlimb suspended rats following endurance training as compared to the control group. Wet weight and relative weight of soleus and plantaris tended to increase, that of gastrocnemius increased significantly, myofibrillar protein content of soleus and plantaris muscle increased significantly and that of gastrocnemius tended to increase in the hindlimb suspended rats following endurance training as compared to sedentary rats following endurance training. Crossectional area of type I fiber of soleus muscle tended to increase, that of type I fiber of plantaris muscle increased significantly and that of type II fiber tended to increase in hindlimb suspended rats following endurance training as compared to sedentary rats following endurance training. The results suggest that endurance training prior to occurrence of muscle atrophy can attenuate the decrease of mass, myofibrillar protein content and fiber crossectional area induced by hindlimb suspension.

Regular long term dance movement could be one of ways to induce improvement of psychophysiological variables, resulting in improvement of quality of life. However, there have been few studies to evaluate the effect of dance movement training on both physiological and psychological variables in the elderly. This study was focused to determine the effect of Korean traditional dance movement training on psychophysiological variables-body weight, body fat, lean body mass, muscle strength, muscle endurance, flexibility, agility, resting heart rate and blood pressure, depression and life satisfaction-in Korean elderly women. Thirty four subjects, aged between 65 and 75years who have normal cognition, sensory function, cerebellum function, cardiovascular function, participated in this study. Seventeen experimental group subjects were selected from E-elderly university in Kyung Gi province, and Seventeen control group subjects were selected from N -welfare facility in Seoul City. Seventeen experimental group subjects participated for 12weeks dance movement program. Korean traditional dance movement program was developed on the basis of Korean traditional dance and music by the author. The program consisted of approximately 50minutes of dance, 3times a week for 12weeks. During 50minutes workout, there were 15minutes of warm-up dancing, 25minutes of conditioning dance and 10minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. The body weight, body fat, lean body mass, muscle strength(grip strength, leg strength), muscle endurance, flexibility, agility, resting heart rate and blood pressure, depression and life satisfaction were measured prior to and following the experimental treatment. The participants in dance movement were interviewed focusing on subjective feeling following 12 week's regular dance movement. Data were analyzed with mean, standard deviation, percentage of change, X2-test, t-test, and ANCOVA test using SPSS PC+ program. Subjec tive feeling was categorized into cognitopsy-chological and physiological responses. Results were obtained as follows: 1) The body weight(F=15.52, p=.000), body fat (F=18.33, p=.000) and lean body mass(F=7.28, p=.011) of the experimental group were significantly lower than those Of the control group following the dance movement training. 2) The leg strength (F=30.96, p=.000), muscle endurance (F=9.06, p=.005), agility(F=44.92, 000), flexibility(F=6.84, p=.014) of the experimental group were significantly higher than those of the control group following the dance movement training. There was no significant difference of grip strength (F=. 43, p=.515) between experimental and control groups. 3) The heart rate(F=26.96, p=.000), systolic (F=10.40, p=.000) and diastolic(F=3.99, p= .005) blood pressure at rest of the experimental group were significantly lower than those of the control group following the dance movement training. 4) No significant difference of score of depression (F=3.49, p=.071) was observed between experimental and control groups. 5) Score of life satisfaction of experimental group was remarkably higher than that of control group following 12weeks of dance movement training (p<0.05). 6) Thematic responses about the dance movement following the training were positive. "I feel good" was the most frequent among cognitopsychol-ogical responses and "I feel lightness of body" was the most frequent among physiological responses. The results suggest that Korean traditional dance movement training can improve psychophysiological variables of Korean elderly.

A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows: 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent-coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on tel-tphone interventions were identified: guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggention, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be unhderstood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for ex tended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

The purpose of this study was to determine the effect of periodic walking during hindlimb suspension on the mass, relative weight, fiber type distribution and cross-sectional area of Type I and II fibers in the developing Type II plantaris muscle. To examine the effectiveness of periodic walking on mass and fiber size, the hindlimbs of young female Wistar rats were suspended(HS group) and half of these rats walked on a treadmill for 45 min/day(15 min every 4 hours) at 5 meters/min at a 15 degree grade(HS-W group) After seven days of hindlimb suspension, the plantaris muscle wet weight was 28.40% significantly smaller (P<0.005) and relative plantaris muscle weight was 26.97% smaller compared with those of control rats(P<0.05). The plantaris muscle wet weight and the relative plantaris muscle weight increased by 46.60% and 49.23% respectively with periodic walking, moreover, the plantaris muscle wet weight and the relative plantaris muscle weight of the HS-W rats recovered to the level of the control rats. No change was observed in fiber type percentage of the developing plantaris muscle following one week of hindlimb suspension or periodic walking during hindlimb suspension. Type I and II fiber cross-sectional areas of the developing plantaris muscle were 42.51% and 43. 68% lower in the HS group than in the control group(p<0.0001), Type I and II fiber cross-sectional areas of the developing plantaris were 30.82% and 45.97% greater in the HS ?W group than in the HS group(p<0.0001), whereas Type I and II fiber cross-sectional area of HS-W group were less than those of the control group(P<0.0001) The results suggest that periodic walking can attenuate developing plantaris muscle atrophy induced by hindlimb suspension.

Exercises are achievement oriented, the process is frequently perceived as hard and difficult. Participants drop out from exercise programs in the middle of the training period. Dance movement, which is the deliberate and systematic use of movement, is enjoyable during the movement and provides opportunities for persons to express themselves. Regular long term dance movement may induce a training effect with a decreased drop out rate. Dance movement could be one way to attain wellness, however, there have been few studies to evaluate both physiological and psychological aspects of dance movement. This study focused on evaluating the effects of dance movement training on body weight, resting blood pressure and heart rate, limb circumference and strength, stress response and subjective feelings. This quasi-experimental study was designed as a nonequivalent control group pre test-post test study. Ten healthy female subjects, aged between 19 and 31 years volunteered for an eight week dance movement program. Ten healthy female subjects, between 19 and 21 years of age paticipated as controls. None of the subjects had performed regular physical activity for six months prior to the study. Dance movement was created with reference to Heber's movement guide. The Dance movement program consisted of approximately 30 minutes of dance, three days per week, for eight weeks. During each 30 minute work out, there were approximately 5 minutes of warm-up dancing, 20 minutes of conditioning dance and 5 minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. Body weight, resting blood pressure and heart rate, circumference of mid upper arm, mid thigh and mid calf, muscle strength of upper and lower limb, physical and psychological response to stress were measured prior to, and following the experimental treatment. Body weight was measured by digital weight scale(Kyung In Corp., Korea). Resting systolic and diastolic blood pressure were measured by sphygmo-manometer. Resting heart rate was measured for one minute in a relaxed sitting position using the radial artery. Circumference of mid upper arm, mid thigh and mid calf was determined by tape measure. Muscle strength of the upper extremities was measured by a grip dynamometer (Takei Corp. No. 1857, Japan) and that of the extremities was measured by the length of time the leg could be held at 45. Physical and psychological responses to stress were measured using the Symptoms of Stress (SOS) Scale. Paticipants in the dance movement were interviewed by the facilitator following the eight weeks, and their thematic responses about the dance movement were recorded. Following the eight week dance movement training, body weight decreased significantly, circumference of mid thigh and mid calf increased. The length of time leg-raising could be held tended to increase following the dance movement training. Resting systolic and resting heart rate showed a tendency to decrease. Total mean score of stress response tended to decrease, and mean score of habitual patterns, depression, anxiety/fear, anger and cognitive disorganization decreased remarkably following the eight week dance movement. Thematic responses about the dance movement were positive following the training.

The purpose of this study was to determine the effect of intermittent low-intensity, short duration exercise during hindlimb suspension on the mass, relative weight, myofibrillar protein content, cross-sectional area of Type I and Type II fibers and SDH activity in Type II (plantaris) muscle. To examine the effectiveness of intermittent low-intensity, short duration exercise on mass, myofibrillar protein content and fiber size, the hindlimbs of adult female Wistar rats were suspended (HS) and half of these rats walked on a treadmill for 45 min/day(9 min every 2h) at 5m/min and a 15grade(HS-EX). Plantaris wet weight was 19.67% significantly smaller(p<0.005) and relative plantaris weight was 6.25% smaller compared with those of control rats following seven days of hindlimb suspension. Plantaris wet weight and relative plantaris weight increased by 27.66%, 12.22% each through intermittent exercise during hindlimb suspension (p<0.005, p<0.05), moreover, plantaris wet weight and relative plantaris weight of the HS-EX rats were similar to those of control rats. Soleus wet weight and relative soleus weight decreased significantly by 31% and 22.0% in the HS rats(p<0.05). Soleus wet weight and relative soleus weight increased by 10. 41%, 25.64% respectively through intermittent exercise during hindlimb suspension, furthermore, soleus wet weight and relative weight of the HS-EX rats were closer to those of control rats. Myofibrillar protein content of plantaris and soleus decreased significantly by 51.49%, 59.65% each, following seven days of hindlimb suspension (p<0.005). Myofibrillar protein content of plantaris and soleus increased by 51.79%, 75.47% each with significance through intermittent exercise during hindlimb suspension(p<0.005). Myofibrillar protein content of plantaris and soleus in HS-EX rats was smaller than that of control rats. No change was observed in fiber type percentage following 1 week of hindlimb suspension or exercise during hindlimb suspension. The type I fiber cross-sectional area of both soleus and plantaris muscle was 18.72% and 41.07% lower in the HS than that of the contro\s(p<0.05,p<0.001), that of both muscles was 6.60% and 29. 34% greater in the HS-EX than that of the HS rats. HS plus intermittent low-intensity short duration exercise resulted in Type I fiber cross-sectional area closer to the controls. Type II fiber cross-sectional area of both plantaris and soleus muscle was 22.45% and 22.58% smaller in the HS than in the controls, that of both muschles in the HS-EX was 14.10%, 5.78% greater than HS. Intermittent exercise during hindlimb suspension resulted in Type I, II fiber cross-sectional area closer to the control value. There was no change in SDH activity following lweek of hindlimb suspension or exercise during hindlimb suspension in the plantaris muscle. The results suggest that intermittent low intensity short duration exercise can ameliorate Type II muscular atrophy induced by hindlimb suspension.

The purpose of this study was to observe the change of circumference, volume and strength of normal 'and operated lower extremities on 3rd, 7th, 10th, and 14th days of postoperation following THRA compared with their condition on preoperation day. Subjects consisted of 13 male and 7 female patients operated with THRA between the age of 20 and 69 years with a mean age of 38.55(SD=15.1). Circumference of upper and lower leg was measured by tape, leg volume was determined according to formula (Moor and Thornton, 1987) with measurement of 8 circumferences of leg. Leg strength was measured by pressing the center of digital health meter in supine position. The results can be summarized as follows: 1. Circumference of operated thigh decreased significantly at 14 following THRA compared with preoperative value, while that of normal thigh decreased significantly at day 3, 7, 10 and 14 after THRA compared with preoperative value. 2. Circumference of midcalf in both operated and normal limb decreased significantly at day 3, 7, 10 and 14 following THRA compared with preoperative value. 3. Leg volume of operated lower limb decreased significantly at 10, 14 following THRA compared with preoperative value, while that of normal limb decreased significantly at day 7 and 10 after THRA compared with preoperative value. 4. Leg strength of operated limb decreased significantly at day 3, 7, 10, 14 following THRA compared with preoperative value. No significant difference of normal leg strength was shown following THRA. 5. Circumference of midcalf differed significantly at day 14 after THRA between normal and operated extremity. From these results, it can be suggested that a decreased activity after THRA caused muscle atrophies in normal and operated extremity.

PURPOSE: This study was to determine the effect of DHEA administration before, during, and after dexamethasone treatment on body weight and TypeI,II muscle weight of rat receiving dexamethasone treatment. METHOD: Wistar rats were divided into 6 groups: control(C), dexamethasone(D), DHEA administration for 3days after dexamethasone treatment for 7days(7D+3DH), dexamethasone treatment for 7days after DHEA administration for 3days(3DH+7D), DHEA administration during dexamethasone treatment for 4days after dexamethasone treatment for 3days(3D+4DDH), DHEA administration during dexamethasone treatment for 7days(7DDH). Dexamethasone was injected by subcutaneously daily at a dose of 5mg/kg. DHEA was orally administered daily at a dose of 5mg/kg for 7 days. Soleus(TypeI) muscle, and both plantaris and gastro- cnemius(TypeII) muscles were dissected on the 7th day of experiment. RESULT: Body weight of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. Body weight of 7D+3DH group decreased significantly compared with that of 7D group, 7DDH group, 3DH+7D group and 3D+4DDH group. Muscle weight of both plantaris and gastro- cnemius tended to decrease compared with that of 7D group. Muscle weight of 7DDH group, 3D+4DDH group and 3DH+7D group increased significantly compared with that of 7D+3DH group. Muscle weight of gastrocnemius of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. CONCLUSION: Based on these results, it can be suggested that DHEA administration before and during dexamethasone treatment can increase both body weight and mass of atrophied TypeII muscle induced by dexa- methasone treatment.

PURPOSE: This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. METHOD: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10degreegrade for seven recovery days. RESULT: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). Type II muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of type II muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. CONCLUSION: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

PURPOSE: The purpose of this study was to determine the effects of exercise program on cardiopulmonary functions and shoulder joint functioning in breast cancer patients who under- went radiation therapy after surgery. METHOD: Subjects in the experimental group(N=12) participated in an exercise program for eight weeks. The Exercise program consisted of shoulder stretching, arm weight training, and walking on treadmill. Maximal oxygen uptake(o2max), maximal running time, shoulder joint range of motion, and shoulder functional assessment were determined before and after the exercise program. Baseline sociodemographic and medical data were compared between experimental group and control group using the Fisher's exact test and Mann- Whitney U test. For effects of the exercise program, repeated measures ANOVA were used. RESULT: 1) Following the exercise program for eight weeks, both o2 max and maximal running time tended to increase in experimental group comparing with the control group. 2) Shoulder abduction, extension and flexion of the operated upper extremity in the experimental group comparing with control significantly increased after the exercise program(p<0.05). 3) Shoulder flexion of the normal upper extremity in the experimental group comparing with control significantly increased after the exercise program(p<0.05). CONCLUSION: The
results
suggest that the exercise program for breast cancer patients undergoing radiation therapy after breast surgery can improve shoulder functions and increase cardiopulmonary functions, which are maximal oxygen uptake and maximal running time.

PURPOSE: To identify age, gender, medication, seasons and place of fall, and areas of the fractures from the fall among the hospitalized elderly patients in order to provide the basic data for future fall prevention program for the elderly.
METHODS
This study was conducted for 106 elderly patients admitted into a university hospital by fractures from the fall during the period from January 1, 1999 to December 31, 1999. Data on the age, gender, medication, season and place of the fall, areas of the fracture were collected based on their medical records.
RESULT
The age range of the subjects were from 60 to 96 years old. The subjects were aged between 60-69 years old 49(46.2%), between 70-79 years old 31(29.2%), between 80-89 years old 24(22.6%), and over 90 years old 2(1.9%). Male patients comprised was 34(28.3%), while female patients comprised 76(71.7%). The fall occurred in Winter most frequently 34(32%). The place of the fall included room 81(76.4%), streets 13(12.3%), bathroom 6(5.7%), stair 4(3.8%), and mountain 2(1.9%). Twenty-two subjects (20.8%) had medication regularly, while 84 subjects (79.2%) had no medication. The areas of the fracture from the fall included upper extremities 20(18.9%) and lower extremities 86(81.1%). Radius fracture (7.5%) was the area where the fracture occurred most frequently in upper extremities and femur fracture (52.8%) was the area where the fracture occurred most frequently in lower extremities. A significant difference was found in the fracture area by age, season and place of the fall (p<.05). No significant difference was found in the fracture area by gender and medication. In all age groups, seasons and places of the fall, occurrence of fracture in lower extremity was significantly higher than that in upper extremity.

A phenomenological study was conducted to investigate the experiences of mothers pregnant via in vitro fertilization (IVF). Sample of nine mothers participated. Ten theme clusters emerged when the formulated meanings were organized into categories. During the infertility period, the participants were subject to self- depreciation, envy, anxiety, and depression. It changed their priorities in life from a job-oriented life to one where having a baby was the most important thing. After trying numerous alternative therapies, IVF became their last hope in having a baby. Since the success rate for IVF is low (only 20-30%), the participants for the treatment were overwhelmed with uncertainty, and it led to further anxiety, depression and despair. Success of pregnancy gave them extreme satisfaction, but they became very cautious in their day-to-day life because of their fear of abortion and early delivery. Some were even worried about the side effect of IVF during the pregnancy. Finally, the delivery of the baby gave them relief from the obligation of having a baby. Women did not have any difficulties in rearing a "test tube baby" except in the case of twins. Most women had no ethical difficulty in having a baby by IVF. However they did not wish this information to be revealed to other people. They again turned to IVF to have a son(s) when the resultory child(s) was a daughter(s). This is because of the strong preference for sons in Korean society.

The purpose of this study was to determine the effect of walk training on leg strength, flexibility, postural stability, balance and gait in home bound elderly women. Eighteen elderly women of the experimental group aged between 70 and 90 years image who have normal vision, hearing and Romberg test. They participated in the 12 week walk training. The subjects of the experimental group practiced walk training 3 times a week for during 12 weeks. During the 40 minute workout, the subjects practiced 5 minutes of warming-up exercises, 30 minutes of conditioning exercises and 10 minutes of a cool-down exercise. The intensity for the conditioning phase was determined by subject' heart rates, which ranged from 60% to 70% of age-adjusted maximum heart rates. The body composition, leg strength, flexibility, postural stability, balance and gait were measured prior to and after the experimental treatment. The body fat, lean body mass, leg strength (ankle dorsiflexor, plantarflexor, inversor and eversir, knee flexor, extensior), flexibility (range of motion of ankle dorsiflexion, plantarflexion, inversion and eversion), and postural stability of the experimental group were significantly greater than those of the control group. Duration of standing on the right foot and that of standing on the left foot of the experimental group was greater than that of the control group. Total balance scores of the experimental group were significantly higher than those of the control group. Among 13 items for balance, the scores of experimental group in balance with eyes closes, turning balance, sternal nudge, neck turning, one leg standing balance and back extension were higher than those of the control group. Total scores of gait of the experimental group were significantly higher than those of the control group following the walking training. Scores of experimental group in step height, step length and walk stance while walking among 9 items for gait were significantly higher than those of the control group. The results suggest that walk training can improve physical fitness for prevention in home bound elderly women.

The purpose of this study was to determine the effect of Korean traditional dance movement training on balance, gait and leg strength in elderly women who are forced to remain at home. Fifteen elderly women of an experimental group between the ages 65 and 75 years who have normal vision and passed the hearing and Romberg test, participated in the 12 weeks' dance movement training. Fourteen subjects of a control group were selected. Korean traditional dance movement training was developed on the basis of Korean traditional dance and music by the authors. It took approximately 50 minutes to perform the dance movement program. The subjects of the experimental group practiced dance training for 3 times a week during 12 weeks. During the 50 minutes workout, the subjects practiced 15 minutes of a warm-up dance, 25 minutes of a conditioning dance, and 10 minutes of a cool-down dance. The intensity for the conditioning phase was between 60% and 65% of age-adjusted maximum heart rates. The balance, gait and leg strength were measured prior to and after the experimental treatment. Total balance scores of the experimental group were significantly higher than those of the control group. Scores of sternal nudge, one leg standing balance and reaching up among 13 items have significantly increased after the dance movement training. Total scores of gait of the experimental group were significantly higher than those of the control group following the korean traditional dance movement training. Scores of experimental group in step height, path deviation and turning while walking among 9 items have increased significantly following 12 weeks of dance movement training. The leg strength of experimental group was significantly higher than those of the control group following the Korean traditional dance movement training. The balance, gait and leg strength have significantly correlated in the experimental group following the Korean traditional dance movement training. The results suggest that Korean traditional dance movement training can improve balance, gait and leg strength in home bound elderly women.

The purpose of this study was to determine the effect of regular exercise during dexamethasone injection in the body weight, weight of hind-limb muscles, myofibrillar protein content and glutamine synthetase activity. 180-200g female Wistar were divided into four groups: control, exercise, dexamethasone injection(dexa), and exercise during dexamethasone injection(D+E) group. The dexa group received daily subcutaneous injection of dexamethasone at a dose of 4mg/kg body weight for 7days. The exercise group ran on a treadmill for 60min/day(20minutes every 4 hours) at 10m/min and a 10degrees grade. The control group received daily subcutaneous injection of normal saline at a dose of 4mg/kg body weight for 7 days. The D+E group ran on a treadmill for 60min/day(20minutes every 4 hours) at 10m/min and a 10degrees grade during dexamethasone injection. Body weight of the control group increased significantly from days of experiment, that of the dexa group decreased significantly from day 4 of the dexa group decrease significantly from day 4 of the experiment resulting in a 82.4% decrease compared to the first day of the experiment. Body weight of the D+E group decrease significantly from day 5 of experiment resulting in a 81.77% decrease compared to the first day of the experiment. Body weights, muscle weight and myofibrillar protein content of the plantaris and gastrocnemius decrease significantly and muscle weight of the sleys tended to decrease with dexamethasone injection. Glutamine synthetase activity of the hind-limb muscles increase significantly with the dexamethasone injection. The relative weight of the soleus was comparable to the control group and that of plantaris decrease significantly and that of gastrocnemius tended to decrease compared to that of the control in the dexa group. Body weight and muscle weight of the plantaris and gastronemius of the exercise group were comparable to the control group, and the muscle weight of soleus showed a tendency to increase. The relative weight of the soleus increased significantly and that of the plantaris and gastrocnemius were comparable to the control in the exercise group. Myofibrillar protein content of the soleus and plantaris increased significantly and there was no change of GS activity of the hind-limb muscles compared to the control in the exercise group. Body weight of the D+E group was comparable to the dexa group, muscle weight of the hind-limb muscles increased significantly. Myofibrillar protein content of the soleus and plantaris increase significantly and that of the gastrocnemius tendency to increase compared to the dexa group. Body weight and muscle weight of the plantaris and gastrocnemius of the D+E group did not recover to that of the control group. Muscle weight of the soleus recovered to that of the control group. The relative weight and myofibrillar protein content of the hind-limb muscles recovered to that of the control group. From these results, it is suggested that regular exercise during dexamethasone injection might attenuate the muscle atrophy of the hind-limb muscles.
