Intra-Session Reliability of Eccentric Countermovement Jump Kinetics in Individuals Six Months After Anterior Cruciate Ligament Reconstruction

Listen to this summary

The authors aimed to evaluate the intra-session reliability and variability of eccentric-phase countermovement jump (CMJ) variables in physically active individuals six months post-anterior cruciate ligament reconstruction (ACLR). They found that Eccentric Peak Force (EPF) and Eccentric Impulse (EI) demonstrated good reliability, while Eccentric Rate of Force Development (RFD) showed moderate reliability and higher variability. These results suggest that EPF and EI may be more reliable metrics for assessing neuromuscular recovery in this population.
