All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
PURPOSE: To investigate the role of vision during depth jump movements and further explore effects of stroboscopic goggles on the motor control of landing. METHODS: Ground reaction force (GRF), rate of force development (RFD), and lower limb surface electromyography measurements were collected on 20 participants (11 male 9 female) across 6 trials of depth jumping (0.51 m) in each of two visual conditions (full vision vs stroboscopic vision). Root-mean-square was estimated from EMG signals that were reduced to specific time-bins (150ms pre touchdown, 30-60ms, 60-85 ms, and 85-120 ms post touchdown). Main effects of and interactions between visual condition and …
