Purpose: This investigation aimed to quantify the typical variation for kinetic and kinematic variables measured during loaded jump squats. Methods: Thirteen professional athletes performed six maximal effort countermovement jumps on fouroccasions. Testing occurred over 2 d, twice per day (8 AM and 2 PM) separated by 7 d, with the same procedures replicated on each occasion. Jump height, peak power (PP), relative peak power (RPP), mean power (MP), peak velocity (PV), peak force (PF), mean force (MF), and peak rate of force development (RFD) measurements were obtained from a linear optical encoder attached to a 40 kg barbell. Results: A …
