Abstract
The purpose in this study was to examine the effect of 18 months exercise program has on body composition, cardiovascular health and isokinetic leg strength in older women living in residential aged care facilities. Nine healthy older women ( 65 yrs) without any overt clinical disease participated in the planed exercise program (2-3 d/wk, 60-70 min/d). Body composition, cardiovascular health, and isokinetic leg muscle strength were measured at pre-intervention, 6-month after intervention, 12-month after intervention, and 18-month after intervention with the same standard operating procedure. The data were analyzed by using descriptive statistics, one-way ANOVA with repeated measures, and Bonferroni post-hoc. In this study, the long-term exercise did not make any change in body weight and body mass index. However, body fat mass and percent body fat were significantly decreased and fat free mass was significantly increased. After the long-term exercise, resting heart rate and blood pressure did not change, but maximal heart rate was significantly increased. In terms of muscle strength, the long-term exercise significantly enhanced bilateral leg muscle strength at all offered isokinetic conditions (60°/sec, 180°/sec, and 240°/sec).BR To conclude, the long-term exercise intervention has a positive effect on body composition and leg muscle strength in older women living in residential aged care facilities.BR
