Each power training session was initiated via a warm-up
consisting of two sets of six submaximal jump squats with
0% 1RM (i.e., CMJ with no external load, just the
resistance applied by a carbon fiber pole (mass = 0.4 kg)
held across the shoulders). During sessions 1 and 3 of each
week, subjects performed seven sets of six maximal-effort
jump squats separated by a 3-min recovery. Jump squats
were performed at the load that maximized power output for
each individual subject, as determined during the baseline
testing session. Similar to previous research, a load consistent with the subject’s body mass (BM; i.e., no external
load or 0% 1RM) maximized power output for each of the
participants in this study (8,11). The second training session
of each week included an additional warm-up set consisting
of five submaximal jump squats with 30% 1RM. Subjects
