Overview

The broad jump is a horizontal jumping movement assessment that evaluates an athlete’s ability to generate horizontal power and maintain stability during landing. This movement is commonly used in athletic assessment and training as it provides valuable information about horizontal power, landing mechanics, and lower extremity function.

Instructions

Dimensions

Required inputs for processing:
  • Arm Position: [‘arm-swing’,‘hands-on-hips’]
