PERFORMANCE RELATED FACTORS IN COUNTERMOVEMENT JUMPS: IDENTIFIED USING A CONTINUOUS SUBGROUP ANALYSIS APPROACH

Abstract

The aim of this study was to examine the benefit of utilizing a subgroup analysis design over a single group analysis design, and determine if performance related factors differ across individuals in countermovement jumping. Joint kinematics and kinetics were used to cluster 122 individuals into four groups, based on their movement strategy. The ability to describe jump height across a single group and subgroup analysis design was assessed to measure the performance of both analysis designs, and performance related factors were identified across the generated clusters. Findings highlight a greater ability of the subgroup analysis design to describe jump height, indicating a benefit of utilizing a subgroup analysis. This is supported by the performance related factors identified, which differed across individuals.
