In an attempt to investigate the effect of a muscle strengthening exercise program on muscle strength, pain, depression, self-efficacy and quality of life of patients with knee osteoarthritis, a pre-experiment, one group pre-test & post-test design, was planned. Muscle strengthening exercise was carried out from May 22 through August 14, 1995 at isokinetic exercise room in rehabilitation department of University Hospital in Taejon. The subjects were seven female clients conveniently sampled from University Hospital located in Taejon, between 39 and 61 years of age, who had a osteoarthritis in knee. Muscle strengthening exercise program was composed of three sessions per week, one isokinetic exercise at angular velocity of 60° and 180° with Cybex isokinetic dynamometer and two resistance home exercise sessions with elastic band. Data were analyzed with frequency, percentage of change, Friedman test, Duncan test using SAS program. Results were obtained as follows : 1) Flexion and extension muscle strength at angular velocity of 60° and 180° were increased after 12weeks' exercise than those of before experiment. But exept flexion muscle strength at angular velocity of 180°(F=3.34, P=0.0261), there was no statistically significant difference among muscle strengths, which is measured every 3 weeks. 2) Pain was decreased after 6weeks' exercise than that of before experiment, and after 12weeks' exercise than that of 6weeks' exercise. There was statistically significant difference (F=4.28, P=0.0396). 3) Depression was increased after 6weeks' exercise than that of before experiment, and after 12weeks' execise than that of 6weeks' exercise. There was no statistically significant difference between before experiment and after 6weeks' exercise. But, there was statistically significant difference between after 6weeks' exercise and 12weeks' exercise(F=9.38, P=0.0035). 4) Self-efficacy was decreased after 6weeks' exercise than that of before exercise. But, it was increased after 12weeks' exercise than that of be-fore exercise and after 6weeks' exercise. But there was no statistically significant difference (F=1.46, P=0.2706). 5) Quality of life was increased after 6weeks' exercise than that of before exercise, and after 6weeks' exercise than that of 12weeks' exercise. But there was no statistically significant differ once (F=1.06, P=0.3816). Thus, the significant of muscle strengthening exercise for the improvement of muscle strength, pain, depression, is verified. But, this study was a pre-experiment with small size subjects. So, con-trolled experimental study is necessary to determine the effect of this muscle strengthening exercise program on muscle strength, pain, depression, self-efficacy, and quality of life of patients with knee osteoarthritis.

Purpose: The purpose of this study is to examine the effects of a resistance band training program on body composition, physical fitness, and health promotion behavior in nursing students. Method: This study has a one-group pretest-posttest design to examine the change in body composition, physical fitness, and health-promoting lifestyle profile after participation in the resistance band training program. Training consisted of hands-based exercises using an elastic resistance band for ten weeks. Participants performed the resistance band training two days per week with a sports trainer, and 30 minutes self-training three days per week. The participants were 21 freshmen in nursing. Results: Mean age of the participants was 20.9 years, and 61.9% were not satisfied with their body shape. After the training program, muscle mass, muscular endurance, and balance of the body were significantly improved. In health promoting lifestyle profile, categories of physical activity, health responsibility, and stress management showed a significant increase. Conclusion: Results of this study suggested that exercising with a resistance band improved body composition, physical fitness, and health promoting behavior in the nursing students. We propose that resistance band training should be suitable for those who have the environment with limitation of time and space.

Background: The conventional deadlift is a popular exercise for enhancing trunk, core, and lower extremity strength. However, its use in sports medicine is constrained by concerns of lumbar injuries, despite evidence supporting its safety and rehabilitative benefits. To optimize muscle activation using resistive bands in variable resistance therapy, we explored their feasibility in the deadlift. Design: Comparative experimental design Methods: Surface electromyography recorded muscle activity in the trunk and lower extremities during lifting, with normalization to the isometric Floor Lift using Maximal Voluntary Contraction. Kinematics were measured using inclinometer sensors to track hip and trunk sagittal plane angles. To prevent fatigue, each subject only used one of the three pairs of bands employed in the study. Results: Our study involved 45 healthy subjects (mean age: 30.4 ± 6.3 years) with similar baseline characteristics, except for years of lifting and strength-to-years-of-lifting ratio. Various resistance band groups exhibited significantly higher muscle activity than conventional deadlifts during different phases. The minimal resistance band group had notably higher muscle activity in the trunk, core, and lower extremity muscles, particularly in the end phase. The moderate resistance band group showed increased muscle activity in the mid-and end-phases. The maximum resistance band group demonstrated greater muscle activity in specific muscles during the early phase and overall higher activity in all trunk and lower extremity muscles in the mid and end phases of the deadlift (p<0.05). Conclusion: Our findings provide valuable insights into muscle activation with various resistance bands during deadlift exercise in clinical and gym settings. There appears to be a dose-response relationship between increased resistance bandwidth, external load, myoelectric activation, and range.

This study examined the effects of a 12-week combined exercise program on blood lipids, albumin, and free fatty acid (FFA) levels in obese, middle-aged women, aged 55-64, who were within five years post-menopause. The participants were divided into two groups: a moderate-intensity exercise group (MIG, n=10) and a high-intensity exercise group (HIG, n=10). Both groups performed resistance exercises using elastic bands and aerobic walking on treadmills three times a week for 60 minutes per session. Data analysis involved calculating the mean (M) and standard deviation (SD) for each measurement item. A two-way repeated measures ANOVA was used to assess interaction effects between groups and periods. Paired t-tests were conducted to evaluate within-group differences over time, and independent t-tests were used to compare between-group differences. The statistical significance level was set at .05 for all analyses. Results showed a significant interaction effect for triglycerides (TG) among the blood lipids (p<.05). No statistically significant difference was found in albumin levels. FFA levels significantly decreased in both groups due to the interaction effect (p<.05), with a more pronounced decrease in the MIG group. These findings indicate that regular exercise is effective in improving and preventing obesity in post-menopausal, obese middle-aged women. Notably, moderate-intensity exercise had a more substantial impact on TG and FFA levels compared to high-intensity exercise. Therefore, continuous moderate-intensity exercise is recommended to improve obesity and promote a healthy lifestyle before transitioning into old age.

Purpose: The study evaluated the effectiveness of health promotion program on the physical fitness and quality of life of elderly women receiving home visiting health care services. Methods: There were 122 elderly women participants. The data were collected between March and December 2019. The participants were provided with the 36-weeks health promotion program consisting of health education, such as nutrition, depression, urinary incontinence, fall, oral care, and exercises, such as stretching, weight-bearing exercise, and elastic resistance training. The balance, muscle strength, flexibility, and quality of life were measured before and after the program. The results were analyzed with paired t-test using the SPSS/WIN 26.0 program. Results: The dynamic balance, muscle strength, flexibility significantly increased. Conclusion: The health promotion program positively affected elderly women in terms of physical fitness, but there are limitations to increasing the quality of life of elderly women. Through this study, it is necessary to be supplemented in improving quality of life of elderly women.

The purpose of this study is to see how the stability of posture due to elastic band during plank movement affects walking. Thirty healthy men in their 20s were given a total of 30 minutes of 10 general plank exercises, 10 plank exercises with two hip joints adduction, and 10 plank exercises with one hip joint adduction. The plank movement was conducted three times a week for a total of six weeks, with a five-minute warm-up. The results of this study are as follows: There was a significant difference between period and group interactions on cadence (p<0.05), with significant difference between the period and group between the left foot on stride length of the left side foot (p<0.05), with significant difference between the period and the period of the interaction between the right foot and the period on stride length of the right side foot (p<0.05), and a one-step change between the right foot and the military interaction on Step time of the right side foot(p<0.05). The conclusion of this study is that the resistance movement on the adduction of both hips increases the instability of the trunk over the normal plank movement and adduction of one hip, thereby enhancing walking ability along with the stability of the trunk.
