Effects of Exercise Intervention on Knee Morphology in Middle-Aged Women: A Longitudinal Analysis Using Magnetic Resonance Imaging

Abstract

This randomized longitudinal study provides no evidence that a 3-month exercise intervention in untrained middle-aged women can significantly alter knee joint morphology. Longitudinal evidence supporting that a training program, successful in increasing physical fitness, can also induce functional adaptation of articular tissues and may protect against knee osteoarthritis, remains to be presented.
