Exercise and Bone Density: Meta-Analysis.
Abstract
Purpose: To use the meta-analytic approach to examine the effects of exercise on bone mineral density in men and women. Scope: The specific aims of this project are to: (1) statistically integrate existing research studies to determine the overall effect of exercise on bone mineral density in adults, (2) determine the effects of potentially confounding variables on changes in bone mineral density, and (3) develop an annotated literature base of exercise and bone mineral density studies. Major findings: Exercise resulted in small, statistically significant effect size (ES) changes in men when bone mineral density sites assessed were specific to the sites loaded during exercise (ES = 0.213, 95% bootstrap confidence interval (BCI) = 0.007 to 0.452). Moderate, statistically significant ES changes were found for older (> 31 years) but not younger (< 31 years) adults, with differences between groups statistically significant (p = 0.04). Moderate to large ES changes were observed at the femur, lumbar, and Os calcis sites in older men. Results/Significance: Site-specific exercise increases and helps maintain bone mineral density at the femur, lumbar, and Os calcis sites in older men. In addition, an annotated literature base on the effects of exercise on bone mineral density was established.
