Key Points

This research aims to assess the impact of pomegranate juice on recovery from exercise-induced muscle damage in collegiate male volleyball players.
Compared pomegranate juice to a placebo in trained male volleyball athletes.
Measured recovery outcomes at 48 hours post-exercise-induced muscle damage (EIMD).
Utilized isokinetic measures to evaluate individual response rates.
Pomegranate juice did not significantly improve recovery outcomes at the group level compared to placebo.
A higher percentage of participants showed meaningful recovery responses to pomegranate juice in specific high-velocity tests.

Abstract

In highly trained male volleyball athletes, short-term POMj did not outperform placebo on group-mean recovery outcomes at 48 h post-EIMD; however, SWC-based analyses showed a higher proportion of meaningful responders with POMj in selected high-velocity isokinetic measures, supporting responder-focused evaluations of recovery nutraceuticals in sport-specific settings.
