text: Following an (cid:6)10-min self-selected whole body loaded 
  barbell-based warm-up and three submaximum warm-up 
  CMJs performed with (cid:6)50% of perceived maximum effort, 
  the WSM performed three maximal effort CMJs, with 30 s of 
  rest between jumps, on a portable Kistler force plate (Quattro 
  Jump, Type 9290AD, Kistler, Switzerland), interfaced with a 
  personal computer. Prior to all jumps, the participant was 
  instructed to stand still on the force plate in an upright pos- 
  ture with their arms by their sides. Sampling was initiated 
  when they provided an indication they were ready to begin, 
  and after a 2-s pause to collect the force due to body mass 
  and a 3-s countdown, the participant performed a CMJ for 
  maximal height, with arm movement and the depth of coun- 
  termovement self-selected by the participant. The Quattro 
  jump device records vertical ground reaction force at a sam- 
  pling frequency of 500 Hz and calculates jump height and 
  peak power using integration/double integration of the force 
  signal (Quattro jump software, type 2822A1-1, version 1.1.1.4) 
  to derive velocity (multiplied by force to calculate power) 
  and displacement (jump height).
