Conditions
Outcome Measures
Primary Outcomes (5)
post-activation performance enhancement (PAPE)
PAPE will be evaluated by maximum height of countermovement jump in this study.
Change in baseline and 1, 3, 5, 7, 9, and 11 minutes after each squat set.
Within-group neuromuscular fatigue
Within-group neuromuscular fatigue will be evaluated by velocity loss rate calculated from maximum and minimum concentric mean velocities of each set for squat in this study.
Up to 2 weeks.
Between-group neuromuscular fatigue
Between-group neuromuscular fatigue will be evaluated by the fastest mean concentric velocity of each squat set in this study.
Up to 2 weeks.
Between-day squat performance
Between-day squat performance will be evaluated by the fastest mean concentric velocity of first squat set for each contrast training in this study.
Up to 2 weeks.
Delayed potentiation of neuromuscular performance (DPNP)
DPNP will be evaluated by maximum height of countermovement jump in this study.
Up to 2 weeks.
