The resistance training program focused on the knee extensors. Subjects trained 3 days/wk for 16 wk. Subjects warmed up on a cycle ergometer or treadmill for ∼5 min or until warm (light sweat) before each training session. Resistance training consisted of three exercises, including knee extension, leg press, and squats. Each exercise was performed for 3 sets at 8–12 repetitions using resistance exercise stations or plate-loaded stations (barbell squats and linear 45° leg press). To accurately compare training and testing loads between weight-stack and free-weight stations, actual resistances were determined for each weight stack using a load cell and regression procedures as our laboratory has described previously (52). The amount of rest between sets was standardized for all subjects at 90 s.
