Design outcomes

Primary

Measure	Time frame
1. Muscle mass (cross-sectional area of vastus medialis) was measured by ultrasound at baseline, 6 (18 training sessions), 12 (36 training sessions), 18 and 24 weeks 2. Muscle strength (peak torque of knee extension) was measured by Cybex with isokinetic (180 and 60 degrees per second) and isometric (knee flexed at 90 degrees) contractions at baseline, 6 (18 training sessions), 12 (36 training sessions), 18 and 24 weeks 3. Physical performance was measured by five-repetition sit-to-stand, timed-up-and-go test and 10-meter walking test at baseline, 6 (18 training sessions), 12 (36 training sessions), 18 and 24 weeks	—

Secondary

Measure	Time frame
1. Proprioception was measured by knee joint repositioning test at baseline, 6 (18 training sessions), 12 (36 training sessions), 18 and 24 weeks 2. Balance was measured by tandem, one-leg stand with eyes open and closed at baseline, 6 (18 training sessions), 12 (36 training sessions), 18 and 24 weeks 3. Voluntary activation was measured by twitch interpolation test at baseline and 12 weeks (36 training sessions)	—
