To examine the combined effects of a high-protein diet and aerobic exercise on body weight and composition and blood lipid profiles in overweight women, 30 young women were recruited and placed into three groups: The high-protein diet and exercise group (HPE), the exercise-only group (EXO) and the control group (CON) (30$\pm$3%, 27$\pm$2%, and 29$\pm$3% body fat, respectively) for an 8-week experimental period. Daily diet included 25% isolated soybean protein (>90% protein, approximately 400 kcal) combined with each subject s usual diet for the HPE group. The exercise program consisted of aerobic-type exercises undertaken >3 times/wk and for>30 min/session at 50-60% of maximal capacity. Physical fitness, body composition, serum total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), triglycerides (TG) and glucose were measured before and after the experiment. Maximal aerobic capacity increased by the end of experiment in both the HPE (from 27.2$\pm$3.5 to 35.l$\pm$5.9 ml/kg/min, p<0.01) and EXO (from 30.3$\pm$5.4 to 33.8$\pm$3.8 mㅣ/kg/min, p<0.05) groups. Percent body fat decreased by 3.3% (p<0.01) in the HPE group and by 1.5% (p<0.05) in the EXO group by the end of the experiment, but not in the CON group. Lower back strength and agility increased only in the HPE group. In the HPE group, TC decreased from 168$\pm$20 to 155$\pm$18 mg/dL and HDL-C increased from 57$\pm$l0 to 61$\pm$9 mg/dL in HPE (p<0.01). But TC and HDL-C did not change in the EXO and CON groups. TG and glucose did not vary among the groups. Although the EXO group showed a similar outcome to that of the HPE group, a favorable change in body composition and blood lipids as well as an improvement in aerobic capacity was more marginal in the latter group.

Purpose : The purpose of this study was to discover which breathing technique is more effective in improving respiratory function by applying different breathing techniques-the chest expansion respiratory technique and the abdominal expansion respiratory technique-to adults in the same aerobic exercise situation. Methods : In this study, 30 people were randomly assigned to two groups: chest expansion respiratory technique with aerobic exercise (A group) and abdominal expansion respiratory technique with aerobic exercise (B group). Group A was asked to breathe after wrapping their rib cage with an elastic band, and Group B was asked to breathe after wrapping their abdomen with an elastic band. A total of 3 sets of 30 breaths were performed, 3 times a week for 6 weeks. For statistical processing, an independent t-test was used to verify homogeneity between the two groups, and a repeated measure analysis of variance (ANOVA) was used to compare differences according to the period for each group. Results : The changes in FVC and FEV₁ for each group following 6 weeks of intervention are as follows. In comparison according to the intervention period, there was a significant increase in all groups depending on the timing of measurement (p<.05), and as a result of the inter-subject effect test, there was no significant difference between groups (p>.05). In addition, there was no interaction effect between period and group (p>.05). Conclusion : The conclusion of this study is that FVC and FEV₁ values increased according to the intervention period in both groups; therefore, it can be suggested that flexible breathing techniques can be applied depending on the patient's physical situation when applying a breathing program to improve respiratory function.

This study examines the combined effects of caloric restriction on body composition, blood lipid, and satiety in slightly overweight women by varying food density and aerobic exercise. Twenty-three women were randomly assigned to one of two groups for a four-week weight management program: the high-energy density diet plus exercise (HDE: n = 12, $22{\pm}2$ yrs, $65{\pm}7$ kg, $164{\pm}5$ cm, $35{\pm}4%$ fat) and low-energy density diet plus exercise (LDE: n = 11, $22{\pm}1$ yrs, $67{\pm}7$ kg, $161{\pm}2$ cm, $35{\pm}4%$ fat) groups. Subjects maintained a low-calorie diet (1,500 kcal/day) during the program. Isocaloric ($483{\pm}26$ for HDE, $487{\pm}27$ kcal for LDE) but different weight ($365{\pm}68$ for HDE, $814{\pm}202$ g for LDE) of lunch was provided. After lunch, they biked at 60% of maximum capacity for 40 minutes, five times per week. The hunger level was scaled (1: extremely hungry; 9: extremely full) at 17:30 each day. Before and after the program, the subjects' physical characteristics were measured, and fasting blood samples were drawn. The daily energy intake was $1,551{\pm}259$ for HDE and $1,404{\pm}150$ kcal for LDE (P > 0.05). After four weeks, the subjects' weights and % fat decreased for both LDE (-1.9 kg and -1.5%, P < 0.05) and HDE (-1.6 kg and -1.4%, respectively, P < 0.05). The hunger level was significantly higher for HDE ($2.46{\pm}0.28$) than for LDE ($3.10{\pm}0.26$) (P < 0.05). The results suggest that a low-energy density diet is more likely to be tolerated than a high-energy density diet for a weight management program combining a low-calorie diet and exercise, mainly because of a reduced hunger sensation.

Purpose: This study aims to analyze the outcome of exercise programs for Rheumatoid Arthritis patients and its tendency with network analysis. Method: 30 articles from Medline search of foreign nursing journals(1966-2002) and 5 from three Korean nursing journals(1970-2002) were surveyed. The contents analyses were focused on outcome measures and network analysis of exercise programs. Results: Exercise programs result in improving muscle strength(91.7%), aerobic capacity(72.9%), and 50 feet walk time(57.3%). Among several exercises, water exercise, and Tai-chi are in the middle of weight-bearing exercises. In the experimental design, non-randomized control trials were 40%, and the functional status of subjects were not classified in 40% of the articles surveyed. Conclusion: Considering the results, muscle strength, aerobic capacity, and 50 feet walk time were tested as valid outcome measures. Tai-chi exercise could be recommended as proper exercise for Rheumatoid arthritis patients because of its low intensity of weight-bearing exercise. In terms of research methods, the randomized trials and functional classifications of rheumatoid arthritis should be done more strictly.

Purpose : The purpose of this study was to determine the effects of 12 weeks of circuit training on inflammatory markers, blood lipids, and body composition of obese middle-aged women. Methods : Twenty-four obese women were randomly divided into three groups (circuit exercise training, CT; aerobic exercise training, AT; resistance exercise training, RT). All the subjects participated in the exercise program for 60 minutes, 3 times a week for 12 weeks. Results : Significant differences found in the participants pre-and post exercise training C-reactive protein (CRP), fibrinogen, and adiponectin levels. The CT participants experience an expected increase in their adiponectin levels. Significantly improved blood TC, LDL-C, HDL-C, and TG levels were found after 12 weeks of exercise. The AT and CT groups showed greater improvements in their HDL-C, LDL-C, and TG levels than the RT group. Significant differences were found in the participants pre-and post-exercise training body weight, body fat percentage, and body mass index (BMI). Conclusion : The CT participants body fat percentages decreased more than the RT group's percentages. In conclusion, obese women who completed 12 weeks of circuit exercise training (aerobics + resistance exercise) had significant improvements in their inflammatory markers, blood lipids, and body fat percentage.

Purpose: The purpose of this study is to investigate the effects of exercising on a stable and unstable surface for a period of six weeks on the arms of female university students in their twenties. Methods: The subjects consisted of 20 female university students. The experimental group consisted of ten individuals who exercised on an unstable surface, and the control group consisted of ten individuals who exercised on a stable surface. The exercise program was composed of aerobic exercises (i.e. Back and forth movements for clapping and raising cross with both arms) and muscle-strengthening exercises (i.e. Push-ups and raising arms). We measured the subjects before the experiment and after the exercise program using the following measurements tool: a ruler and T-scan plus. The same person measured changes in arm size with a ruler three times and calculated the average to minimize any errors in measurement. We controlled the subjects to measure the amount of arm muscle with a T-scan plus. Twelve hours before the measurements were taken subjects were not permitted to exercise, and four hours before the measurements were taken subjects were not permitted to eat anything. Results: The two groups had no significant difference, but each group felt the effect of the exercise program. Conclusion: There was no difference between the experimental group and the control group. However, it was determined that the exercise had a greater effect on an unstable surface than a stable surface.

The purpose of this study was to analyze the effect of different types of rehabilitation training program on the kinetic and kinematic parameters during sit-to-stand movement(STS) in chronic stroke patients. Two groups of hemiparetic patients, experimental and control, participated in the study. The experimental group participated in a 10-week training program (three sessions/wk, $1{\sim}1.5\;hr/session$) consisting of a warm-up, aerobic exercises, lower extremity strengthening. and a cool-down. The control group participated in an aerobic exercise. Three dimensional kinematic analysis and force platform; were used to analyze the duration of STS, lower extremity angle, and weight bearing ability. The experimental group which had more strength of lower extremity displayed decrease in duration of STS. However, the control group showed increases in duration during sit-to-stand movement. The control group flexed their trunk more than the group did Therefore, it took more time to extend their trunk during STS. The duration in sit-to-stand was affected by the strength of lower extremity and the angle of trunk movement. The angles of ankle and knee joint had an influenced on duration of STS. The post experimental group performed with their feet near the front leg of the chair during sit-to-stand, therefore the duration was decreased. The repetitive sit-to-stand movements as a resistance exercise was effective to hemiparetic patients in learning mechanism of sit-to-stand. The control group showed decreased differences in the vertical ground reaction forces between paretic and non-paretic limbs. Their training program included strengthening exercise that may help improving weight bearing ability. The control group showed increases in the center of pressure in the anteroposterior and mediolateral displacement. This means that the stability of movement was low in the control group. Their training program which combined aerobic and strengthening exercises that are more effective to improve the stability of movement.
