Reliability of bilateral and shear components in a two-legged counter-movement jump

Strength asymmetry can be detrimental to athlete performance and may lead injury. The countermovement jump (CMJ) used measure strength via shear force production. reliability of parameters effects production on vertical CMJ were evaluated in a study with 15 university-level sprint high athletes ( m = 11, f 4). performed three CMJs two occasions, separated by 1 week. Tri-axial ground reaction (GRF) was recorded using platforms embedded within bespoke weight training area. Key metrics calculated real-time describing total performance, Changes the means coefficients variation (CV) express reliability. Twenty-six from Total analysis 21 Asymmetry showed CV lower than 10%. Temporal kinetic variables highlight compared equivalent derived analysis. Shear show levels measures methods described this work shown reliable for monitoring performance. No significant negative relationships found between or traditional (e.g. height, specific peak power force). Further is required identify potential reducing
