Abstract
Monitoring kinetic asymmetry may provide coaches with a modifiable variable to improve performance. The purpose of this study was to determine the prevalence and relationship of kinetic asymmetry during a countermovement jump (CMJ) and jumping performance. 26 elite American football players performed drop jumps onto an electronic timing mat and CMJ onto a force plate. Kinetic asymmetry was assessed calculating a symmetry index (SI) from inter-limb peak vertical ground reaction forces at propulsion during the CMJ. Pearson correlation coefficients quantified relationships between SI, reactive strength and jump height from the drop jumps, and jump height from the CMJ, p10%. SI was not significantly associated with any variables. p>.05. Players may compensate for asymmetry in a manner that preserves performance.
