Abstract

This study addresses the challenge of accurately estimating Horizontal Ground Reaction Force (hGRF) from Vertical Ground Reaction Force (vGRF) in the Counter-Movement Jump (CMJ) test. While vGRF is pivotal for quantifying vertical jump height, understanding hGRF provides insights into horizontal propulsion and overall jump efficiency. Athletes (n=40) who participated in the AIU Athletics championship were asked to perform the Counter-Movement jump in Kistler force plates. The force data was measured through bilateral Kistler Force plate model 9287CA with dimensions 1200x600x100 and analyzed using MARS software. Multiple regression in Microsoft excel showed that the hGRF accounts for 49.96% of vGRF and is statistically significant. This research contributes to refining jump biomechanics understanding, aiding practitioners in extracting comprehensive insights from standard jump-testing protocols.
