For the prescription of resistance exercise, 1RM strength was assessed in the free-weight (i.e. arm curl, and bench press) or machine exercises (i.e. leg press, calf rise, knee flexion, and lat pull down) using previously described methods [23]. Subjects performed a warm-up specific to this test consisting of eight to ten repetitions using a light weight (i.e., 50% of 1RM), three to five repetitions using a moderate weight (i.e., 75% of 1RM), and one to three repetitions using a heavy weight (i.e., 90% of 1RM). Then, resistance was increased until participants were unable to complete an attempt using proper technique through a full range of motion. Up to five maximal attempts were allowed, with 5 min of rest between attempts. Spotters and investigators were present to provide verbal encouragement and ensure safety.
