Relationships between strength, jump and kinematic variables during resisted sled sprinting

Abstract

Resisted sprint training revealed positive and negative effects on sprint performance across multiple loading conditions [1, 2]. This variation to performance may be due to that some of the heavier players may not be as strong as some of the lighter players and vice versa [3]. Further, it is unclear whether heavy loading negatively impacts sprint kinematics for stronger athletes in the same manner as for weaker. Aims: Examining the relationships between: • change in kinematics and back squat and hip thrust strength measures, • strength and sprint performance, • strength and vertical jump performance, • sprint performance and vertical jump performance.
