Purpose : This study aimed to determine the effects of a 12-week program of beta-glucan intake and muscle strengthening exercises on the body composition, physical fitness, blood lipids, insulin and insulin resistance of adult women. Methods : For this study, 45 adult women were selected and divided into two groups : the experimental group (n= 25), which received a combination of beta-glucan and strength exercise, and the control group (n= 20), which received only strength exercise. The program was conducted for 50 minutes three times a week for 12 weeks. Results : Several significant differences were found in both groups pre-to post program. First, in both groups, there were significant differences in hip circumferences (p<.05). Second, the results showed significant improvements in left grip strength and sit-ups achieved (p<.05), right grip strength (p<.001). Third although the results show no significant post-program differences in either group, there was a significant pre-to post-program difference in free fatty acids in both groups (p<.05). Fourth, the results show no significant differences in insulin or insulin resistance in either group, nor do they show any significant differences between the groups. Conclusion : The above results indicate that both groups exhibited decreased hip circumference and increased muscle strength (left grip strength) and muscle endurance. Furthermore, they indicate that when the beta-glucan intake and exercises were combined, the effects were more pronounced. Finally, because both groups exhibited significant increases in fat-free mass, muscle mass, skeletal muscle mass, muscle strength (right grip strength), and coordination as well as decreases in free fatty acids, it can be concluded that both the combined program of beta-glucan intake and exercise and a program of exercise alone can positively affect these outcomes.

Purpose : People who have suffered from COVID-19 suffer from decreased pulmonary function and various side effects. This study aims to present three respiratory exercise intervention methods to improve pulmonary function in COVID-19 survivors. Therefore, the purpose of this study will investigate the effects of breathing exercise interventions (aerobic exercise, diaphragm breathe exercise, and inspiratory muscle training on resistance) on pulmonary function in COVID-19 survivors. Methods : The subjects who participated in this study were 35 male and female college students confirmed with COVID-19. All subjects were randomly assigned to A, D, and I groups according to breathing exercise intervention method. Groups A, D, and I each performed aerobic exercise, diaphragm breathing exercise, and inspiratory muscle training on resistance, 3 times a week for 6 weeks. Pulmonary function was measured using a spirometer, and FVC (forced vital capacity), FEV₁ (forced expiratory volume in one second), FEV₁/FVC % (forced expiratory volume in one second / forced vital capacity ratio), and PEF (peak expiratory flow) were measured at 0, 3, and 6 weeks. Data analysis was compared by repeated measures analysis of variance, and post hoc tests for time were compared and analyzed using paired t-tests. Results : In the results of this study, FVC values showed statistically significant improvement in all groups. FEV₁ values also showed statistically significant improvement in all groups. And the FEV₁/FVC % value also showed statistically significant improvement in all groups. And the PEF values also showed statistically significant improvement in all groups. Conclusion : The results of this study reported that aerobic exercise, diaphragm breathing exercise, and resistance inspiratory muscle training were all effective in improving pulmonary function in COVID-19 survivors. Therefore, application of the three breathing exercise intervention methods presented in this study will help improve pulmonary function in COVID-19 survivors.

Purpose : The purpose of this study was to investigate the effect of exercise using a suspension device (sling and total body resistance exercise; TRX) on physical functional performance and postural balance. Methods : An experimental study comparing 2 different suspension exercise was conducted on 16 healthy college students. 16 subjects were assigned to two groups. They were classified into 8 sling group and 8 TRX group. Miniplus was used to evaluate physical functional performance. In this study, isokinetic resistance mode was used to compare and analyze seven movement patterns. Biorescue was used to evaluate postural balance. The intervention exercises in this study are as follows. Standing lean forward (SLF) using a sling and TRX was performed 3 times a week for 3 weeks. The SLF was held for 10 seconds and then rested for 15 seconds, repeated a total of 10 times for 3 sets. Results : In the TRX group, significant increases were observed in physical functional performance (p<.05). Among the differences between groups, significant differences were confirmed on the front of the right arm, the back of the left arm, and the back of the right arm. In the sling group, significant increases were observed in left, right, front, and overall dynamic balance (p<.05). A significant increase in posterior dynamic balance was confirmed in the TRX group (p<.05). There was no significant difference between groups. Conclusion : Based on the results of this study, TRX was effective in improving physical functional performance, while the sling was effective in enhancing postural balance. However, confirming the effectiveness of slings and TRX in the relationship between physical functional performance and postural balance proved inadequate. Therefore, additional research should be conducted to verify the effects of suspension.

Purpose: To investigate the effect of progressive resistance training (PRT) on body composition, physical fitness, quality of life, lipid and nutritional profile of patients on hemodialysis (HD). Methods: A non equivalent comparison group pretest and posttest design study was used with 40 participants who were randomly assigned to the exercise group (20 participants) and the comparison group (20 participants). The exercise group received PRT for 30 minutes per session, 3 sessions a week, for 12 weeks, while the comparison group received usual care. The PRT consisted of upper and lower body exercises using elastic bands and sandbags. Outcome measures evaluated were: body composition, physical fitness, quality of life, and lipid profile. Results: Skeletal muscle mass, grip, leg muscle strength, and quality of life all improved significantly in the exercise group. Body fat rate, total cholesterol and triglyceride rate decreased significantly in the exercise group. Conclusion: These results suggest that PRT improves body composition, physical fitness, quality of life, and lipid profile of patients on HD. PRT using elastic bands and sandbags can be utilized as part of a regular care plan for these patients.
