This study compares forearm bone mineral content (BMC) in older women with forearm muscular strength, with forearm muscular endurance, and with general cardiovascular endurance. Thirty-one postmenopausal women (aged 65-85) were tested for bone mineral content (BMC) at the 1/3 and 1/20 distal locations on the radius of the non-dominant forearm. Forearm strength was assessed with a grip dynamometer, forearm endurance with a wrist curl test, and cardiovascular endurance with a step test. There were significant correlations between forearm strength and both cortical and trabecular BMC (P < 0.05). No significant correlations were found between either of the endurance measures and BMC. These findings suggest that perhaps high resistance strength-development types of exercises may be more effective than lower resistance endurance-building types of activities relative to increased bone density.
