Summary

The present study aimed to compare the acute effects of cluster-set (CS) and traditional-set (TS) plyometric loading protocols on countermovement jump (CMJ) performance and reactive strength index (RSI-mod) in young tennis players.

Twenty-eight male tennis players (age: 16.7 ± 1.3 years) were randomly assigned to either a CS or TS group. Following a familiarization session, participants completed an experimental session including pre-tests (CMJ and drop jump), a plyometric loading protocol (CS: 3 × \[5 × 2 repetitions, 15 s intra-set rest, 2 min between sets\]; TS: 3 × 10 repetitions, 3 min between sets), and post-tests at 15 s, 3 min, and 6 min. CMJ height and RSI-mod were assessed using the My Jump 2 application. Borg Scale, Total Quality Recovery (TQR) were apply after post-tests at 15 s, 3 min, and 6 min.
