Changes in the force-time curve during a repeat power ability assessment using loaded countermovement jumps

A reduction in force during the late propulsive phase is evident as the LCMJ20 progresses. SPM analysis provides refined insight into where changes in the force-time curve occur during performance of the LCMJ20. Participants with the lower RPA<sub>%dec</sub> scores displayed both larger braking and propulsive forces across the LCMJ20 assessment.

Abstract

A reduction in force during the late propulsive phase is evident as the LCMJ20 progresses. SPM analysis provides refined insight into where changes in the force-time curve occur during performance of the LCMJ20. Participants with the lower RPA<sub>%dec</sub> scores displayed both larger braking and propulsive forces across the LCMJ20 assessment.
