Abstract

Introduction: Slow gait predicts many adverse clinical outcomes in old adults, but the mechanisms of how power training can minimize the age-related loss of gait velocity is unclear. We examined the effects of 10 wk of lower extremity power training and detraining on healthy old adults' lower extremity muscle power and gait kinematics. Methods: As part of the Potsdam Gait Study, participants started with 10 wk of power training followed by 10 wk of detraining (n = 16), and participants started with a 10-wk control period followed by 10 wk of power training (n = 16). We measured gait kinematics (stride characteristic and joint kinematics) and isokinetic power of the ankle plantarflexor (20 degrees.s(-1), 40 degrees.s(-1), and 60 degrees.s(-1)) and knee extensor and flexor (60 degrees.s(-1), 120.s(-1), and 180 degrees.s(-1)) muscles at weeks 0, 10, and 20. Results: Power training improved isokinetic muscle power by similar to 30% (P
