Objective To determine the effect of exercise frequency on various diseases and risk factors of the elderly. Design Retrospective analysis of a randomized controlled 18-month exercise trial. Setting University ambulatory group setting. Participants Community-dwelling women aged ≥65 years (N=162) in the area of Northern Bavaria. Intervention Mixed, intense aerobic, resistance, and balance protocol for 18 months. Subjects were retrospectively subdivided into 2 groups according to their effective attendance over 18 months (>1 Main Outcome Measures Bone mineral density (BMD), lean body mass, appendicular skeletal muscle mass by dual-energy x-ray absorptiometry, Framingham study-based 10-year coronary heart disease (CHD) risk, and number of falls by calendar method. Results Significant differences between the low-frequency exercise group (LF-EG) and the high-frequency exercise group (HF-EG) were observed for lumbar spine BMD (HF-EG, 2.4%+2.8% vs LF-EG, 0.3%+2.2%; P<.001 and proximal femur bmd vs lf-eg p=".014)," lean body mass appendicular skeletal muscle no differences between both exercise groups were observed for chd risk number of falls comparing the with less active control group only nonsignificant effects fall evaluated.> Conclusions Although this result might not be generalizable across all exercise types and cohorts, it indicates that an overall exercise frequency of at least 2 sessions/wk may be crucial for impacting bone and muscle mass of elderly subjects. |
