Abstract
MEN WITH VARIOUS LEVELS OF resistance-training experience trained with explosive jump squats using either 30% (JS30; higher velocity) or 80% (JS80; lower velocity) of their 1-repetition maximum (1RM) squat. JS30 increased peak power (PP) and peak velocity in jump-squat testing across various loads (30, 55, and 80% 1RM), and 1RM squat, and showed a trend toward increasing 20-m run performance. JS80 improved peak force and PP in slower/heavier -load (55 and 80% 1RM) jump-squat testing, increased 1RM squat but led to a slower 20-m sprint. It appears that adaptations followed somewhat of a velocity-specific pattern with broader transfer from the JS30. McBride, J.M.,T. TriplettMcBride, A. Davie, and R.U. Newton.
