Abstract

BMX Supercross (SX) racing technique has developed from the experiential knowledge of coaches and athletes. Quantitative analysis has been difficult due to the environment in which these races occur. Ecological validity in quantitative biomechanics has been has been shown to be important with field results differing from laboratory results in cycling activities [1].

This study quantifies the validity and intra-tester reliability of a 2D method for calculating sagittal plane kinematics during the BMX SX gate start action that utilises GoPro Hero® 4 Black 120 fps cameras and Kinovea software. This technique was used to analyze the symmetry of the sagittal kinematics of the upper body of elite BMX athletes.
