Abstract
The ground reaction force (GRF) waveform during countermovement jumps (CMJs) is considered to reflect neuromuscular coordination strategies; yet the biomechanical mechanisms distinguishing unimodal from bimodal patterns remain unclear. This study investigated the influence of countermovement depth and velocity on GRF waveform shape and examined their relationship with joint moments and work. Twenty-six healthy young women (age: 22.1 ± 1.1 years; height: 160.8 ± 4.0 cm; body weight: 53.5 ± 5.6 kg) performed CMJs, and GRF waveforms were categorised as unimodal and bimodal patterns.
