Joint velocities during jump over time
Nettet22. mar. 2024 · These results indicate a requirement to evaluate movement quality over time by measuring peak hip and knee flexion angular velocities during the landing phase during fatigue conditions. In addition, it may be necessary to evaluate these parameters at each peak variable and at specific times such as 40 milliseconds after initial ground …
