The effect of group exercise frequency on health related quality of life in institutionalized elderly

INTRODUCTION: Introduction: the study aimed to determine the effect of group exercise frequency on health related quality of life in institutionalized elderly. METHODS: one hundred participants were recruited for voluntary participation from five aged care facilities, with inclusion being based on the outcome of a medical assessment by a sports physician. RESULTS: a significant difference was noted in social function post training twice (MD = -13.85, 95% CI -24.66, -3.38, p = 0.017, d = 0.674) and thrice (MD = -13.30, 95% CI -21.81, -5.59, p = 0.003, d = 0.712) a week. Training thrice a week provided an additional benefit in vitality (MD = -7.55, 95% CI -13.16, -1.91, p = 0.018,d =0. 379). Improvements in mental component summary scale post training twice (MD = -4.08, 95% CI -7.67, -0.42, p = 0.033, d = 0.425) and thrice (MD = -6.67, 95% CI -10.92, -2.33, p = 0.005, d = 0.567) a week was further noted. CONCLUSION: mental health and social health benefits can be obtained irrespective of exercise frequency 2X/week or 3X/week.The exercise intervention at a frequency of thrice a week was more effective in improving mental component summary due to a larger effect size obtained compared to the exercise frequency of twice a week. Additional benefits in vitality wasachieved by exercising 3X/week. This may assist the elderly in preserving their independence.
