Comparing plyometric training methods on speed, change of direction, and jump performance in young soccer players: A controlled study.

This article focuses on comparing the effects of cluster set (CS) and traditional repetition (TRD) plyometric training methods on jump performance, speed, and change of direction (COD) in young male soccer players over six weeks. The randomized controlled study involving 30 under-15 athletes found that while both CS and TRD groups showed within-subject improvements in countermovement jump (CMJ) and 30-meter sprint (T30), neither training method outperformed a control group engaged in regular soccer training, which demonstrated superior COD performance. No significant differences were observed between CS and TRD groups across the measured variables, and standing long jump (SLJ) performance did not improve significantly in any group. The findings suggest that regular soccer training may be sufficient for maintaining or improving these physical attributes in youth athletes, and that plyometric training protocols might require adjustments in volume, intensity, or exercise specificity to elicit greater performance gains.
