Effects of high-velocity resistance training on muscle function, muscle properties, and physical performance in individuals with hip osteoarthritis: a randomized controlled trial

This report has been verified by one or more authors of the original publication.

46 women with various severities of hip osteoarthritis were randomized to undergo an 8-week home-based training program of either high-velocity or low-velocity exercises. The purpose of this study was to determine if high-velocity training offered any advantages over low-velocity training. Physical performance measures, muscle strength, power, thickness and composition, and clinical outcomes were measured at program completion. Statistically significant effects of high-velocity training were displayed in the Timed Up-and-Go test and composition of the gluteus maximus, although all other outcomes were similar between the high-velocity and low-velocity groups.
