OBJECTIVES Peak power declines more precipitously than strength with advancing age and is a reliable measure of impairment and a strong predictor of functional performance. We tested the hypothesis that a high-velocity resistance-training program (HI) would increase muscle power more than a traditional low-velocity resistance-training program (LO). DESIGN(More)
OBJECTIVES The purpose of this study was to assess the influence of leg power and leg strength on the physical performance of community-dwelling mobility-limited older people. DESIGN Cross-sectional analysis of baseline data from a 12-week randomized controlled exercise-intervention study. SETTING Exercise laboratory within the Department of Health(More)
OBJECTIVES To evaluate weighted stair climbing exercise (SCE) as a means of increasing lower extremity muscle power in mobility-limited older people. DESIGN Single-blinded, randomized controlled pilot study. SETTING Human physiology laboratory of a metropolitan university. PARTICIPANTS Forty-five community-dwelling people aged 65 and older who had(More)
The neuregulin/erbB-signaling axis contributes to the development and growth of multiple mammalian tissues including skeletal muscle. In this study, we sought to characterize the native expression of this system in human skeletal muscle and test the hypothesis that a program of progressive resistance training (PRT) would regulate the expression of(More)
