Countermovement Jump And Squat Jump Force-Time Curve Analysis In Control And Fatigue Conditions, Steven Hughes, John Warmenhoven, G. Gregory Haff, Dale W. Chapman, Sophia Nimphius

Research outputs 2014 to 2021

This study aimed to reanalyze previously published discrete force data from countermovement jumps (CMJs) and squat jumps (SJs) using statistical parametric mapping (SPM), a statistical method that enables analysis of data in its native, complete state. Statistical parametric mapping analysis of 1-dimensional (1D) force-time curves was compared with previous zero-dimensional (0D) analysis of peak force to assess sensitivity of 1D analysis. Thirty-two subjects completed CMJs and SJs at baseline, 15 minutes, 1, 24, and 48 hours following fatigue and control conditions in a pseudo random cross-over design. Absolute (CMJ_ABS/SJ_ABS) and time-normalized (CMJ_NORM/SJ_NORM) …
