The purpose of this study was to investigate the effect of aquatic exercise on the isokinetic muscular function in the older women. Forty volunteers were placed in 2 groups: aquatic exercise group(n=20), and general aerobic exercise group(n=20). The subjects who joined this investigation were asked to participate in the program(3 times/week, 60min/day) for 12 weeks. Muscular strength was evaluated by peak torque and peak torque/BW of the knee extensor and flexors at 60 deg/sec(3 repetitions), endurance by total work and work fatigue of the knee extensor and flexors at 180 deg/sec(26 repetitions), Ispilateral balance ratio, and Bilateral balance ratio using Isokinetic Rehabilitation and Testing System(Biodex system 3 pro., U.S.A.) at the beginning and the end of the 12-week program. For data analysis, mean and standard deviation scores were calculated, and repeated two-way ANOVAs were used.After 12-weeks, the results of the study are as follow; First, most muscular strength, muscular endurance, and bilateral bance ratio in both group were significantly improved. Second, The aquatic exercise group were significantly better than the general aerobic exercise group on muscular strength(right) of extensor, muscular strength of flexor, ispilateral balance ratio, and bilateral balance ratio. Therefore, this study implies that the aquatic exercise may be of benefit to isokinetic muscular function of knee joint in elderly women.

The purpose of this study vow to investigate the effect of c piton-action coupling exercise on posture balance in the elderly. The subject(n=42) were assigned to 2 groups: perception-action coupling exercise(PACE) group(n=20, 68.00±4.50 yrs) and general exercise(GE) group(n=22, 67.33±4.85 yrs). The subs were asked to participate in participation coupling’s exercise program or general exercise program(3 times/week 80min/day) for 12 weeks. The subjects were used on static posture balance(eyes open and close) and dynamic posture balance(anterior and posterior) at the beginning and the end of the 12-weeks program For data analysis, toad root mean square values were calulated and independent t-tests and 2 way-ANOVA we used.After 2 different exercise programs for 12 week, both groups did not show any change on static posture balance. But PACE group was better than GE program group on dynamic posture control ability. Therefore, this study may suggest that exercise program based on perception-action coupling improves posture balance in the elderly, and further becomes an effective way that prevents from falling.

본 연구는 다이내믹 시스템 이론에 기초한 운동프로그램이 다른 감각기능 수준을 가진 노인들의 동적 평형성에 미치는 영향을 알아보는 것이다. 총 32명(67.72±2.89세)의 여성 노인을 대상으로 총 4집단으로 나누어 구성하였다; A 집단은 상대적으로 높은 감각기능 수준을 가지고 다이내믹 운동(DSE) 프로그램을 적용한 집단, B집단은 상대적으로 높은 감각기능 수준을 가지고 일반적인 운동(GE) 프로그램을 적용한 집단, C집단은 상대적으로 낮은 감각수준을 가지고 DSE 프로그램을 적용한 집단, D집단은 상대적으로 낮은 감각수준을 가지고 GE 프로그램을 적용한 집단. 모든 대상자들은 12주간의 운동프로그램 전·후에 걸쳐 동적 평형성 검사를 실시하였다. 각기 다른 운동프로그램을 적용한 12주 후에 DSE 프로그램을 적용한 모든 집단의 동적 평형성이 향상되었고, 감각기능 수준과 관계없이 DSE 프로그램을 적용한 후 GE 운동프로그램 집단 보다 DSE 프로그램을 적용한 집단의 동적 평형성이 더 뛰어난 것으로 나타났다. 따라서 DSE 프로그램은 노인들의 동적 평형성을 향상시키는데 유용하며, 이는 노인들의 낙상을 예방하는 효과적인 방법이 될 수 있을 것이다. The purpose of this study was to investigate the effect of dynamic system theory-related exercise program on dynamic balance in the elderly with different sensory level. The subjects were old women 32(67.72±2.89 yrs) who were all volunteered. There were 4 groups: A group(n=8, 67.50±2.14 yrs) with higher sense and DSE(dynamic system's exercise) program, B group(n=8, 67.75±3.49 yrs) with higher sense and GE(general exercise) program, C group(n=8, 68.00±3.02 yrs) with lower sense and DSE program, and D group(n=8, 67.63±3.29 yrs) with lower sense and GE program. The subjects were tested on dynamic balance before and after 12 weeks program. For data analysis, mean and standard deviation scores were calculated, and ANCOVA, and Bonferroni test were used. After 2 different exercise programs for 12 weeks, dynamic balance was improved in all subjects of DSE program groups, and regardless of sense levels, DSE program groups were better than GE program groups on dynamic balance. Therefore, this study may suggest that DSE program improves dynamic balance in the elderly, and further becomes an effective way that prevents from falling.

The purpose of this study was to investigate the effect of supplemental PNF-weight training and detraining on daily activity-related physical function(DAPF) and isokinetic muscular function in the older women. Forty-two volunteers, who had been participating in aerobic exercises for the preceding 12 weeks, were placed in 2 groups: Experimental group(n=24, age=67.75±3.53) continued PNF-weight training, and control group(n=18, age=67.78±3.21) continued only aerobic exercise. The subjects who joined this investigation were asked to participate in the program(3 times/week, 60min/day) for 12 weeks. DAPF was measured on muscular strength, flexibility, agility/dynamic balance, aerobic endurance, and BMI. Muscular strength was also evaluated by peak torque of the knee extensor and flexors at 60 deg/sec(3 repetitions) and endurance by total work of the knee extensor and flexors at 180 deg/sec(26 repetitions) using isokinetic exercise machine before and after 12 weeks program, and again after 2 weeks and 4 weeks of detraining. For data analysis, mean and standard deviation scores were calculated, and repeated two-way ANOVAs were used.After each 12 weeks training and detraining, the results of the study were as follow: First, after 12 weeks training and 2 weeks, PNF-weight training group was better than aerobic exercise group on muscular strength of lower and upper body, flexibility of lower body, agility/dynamic balance, and isokinetic strength and endurance of knee joint muscles. But after 4 weeks of detraining, both groups showed the same levels as before 12 weeks training. Second, after 12 weeks training both groups did also significantly improve flexibility of upper body and aerobic endurance, but after 2weeks and 4weeks of detraining they showed the same levels of variables as before 12 weeks training. Third, even though both groups didn’t show any change on BMI after the training and 2 weeks detraining, they were significantly increased on BMI after 4 weeks of detraining. Therefore, the present findings suggest that PNF/weight training may be of benefit to DAPF and isokinetic strength/endurance of knee joint muscles for improving and long-lasting in the elderly women.

The purpose of this study was to investigate the effects of gender and activity level on physical function, psychological function, & health-related quality of life(HRQL) and the relationship among physical/psychological function, & HRQL All subjects who have experienced physical activities over 1 year(male n=90, age=69.83±3.46; female n=118, age=68.91±3.52) were tested on the physical activity levels(frequency/week), physical functions(strength, flexibility, balance, cardiorespiratory endurance, & BMI), psychological functions(depression, self-efficacy, physical-efficacy, & life-satisfaction), & HRQL For data analysis, two-way ANOVA, Duncan test, and Pearson’s correlation coefficient were used.First, depending on physical activity levels, the elderly showed significant differences on physical/psychological functions, and HRQL: 1) the physical activity levels affected to most of physical functions except for BMI, the male older adults were significantly better than females older adults on upper/lower-body muscular strength, upper/lower-body flexibility, & agility, but not on stability & cardiorespiratory endurance. 2) The physical activity levels significantly influenced on psychological functions(depression, self-efficacy, physical self-efficacy, life-satisfaction). Meanwhile, male older adults were significantly higher than female older adults on psychological functions. 3) The physical activity levels significantly influenced on the HRQL. Meanwhile, male older adults were significantly higher than female older adults on the HRQL. Second, the elderly showed significant relationships among physical/psychological function, & HRQL: 1) the higher older adults had physical functions(muscular strength, agility, & stability), the better they were on psychological functions(physical self-efficiency & life-satisfaction) & HRQL. 2) The higher they had psychological functions(depression, physical self-efficiency, & life-satisfaction), the better they got HRQL. Therefore, this study may imply that physical activities cause to improve physical functions, psychological functions, and then, in turn, quality of life in the elderly.
