Summary

This study aims to identify differences in lower-extremity strength and power between elite ice hockey players with and without patellar tendinopathy using unilateral and bilateral comparisons. It applies a structured, cross-sectional methodology that combines clinical screening, performance testing, and ultrasound imaging to characterize patellar tendon structure and lower-limb function in elite hockey players. Players are objectively classified into healthy, unilateral, or bilateral patellar tendinopathy groups based on standardized ultrasound criteria. Strength and power outcomes are assessed under controlled conditions and normalized to body mass to allow fair between-group comparisons. Isokinetic concentric strength is evaluated during a split squat performed on a robotic resistance device, while peak power output is measured using a six-second all-out cycling test on a calibrated ergometer.
