then performed five sets of five maximal-effort jump squats
with 30% 1RM separated by a 3-min recovery. Intensity
was modified for each session so that an audible beep could
be heard by subjects during jumps that reached 95% of the
maximal power output at that load from their previous
training or testing session. Previous literature has shown
significant performance improvements after jump squat
training with similar programming parameters at both 0%
1RM (10) and 30% 1RM (25,39).
