Brief Summary

Players were randomly assigned to a two-times-a-week (2PLYO, n = 15) or four-times-a-week (4PLYO, n = 15) PT (Plyometric Training) group. Both groups performed the same weekly total volume of jumps during PT in addition to regular basketball training and competition. The 2PLYO group performed 240 jumps over two sessions (120 jumps per session), and the 4PLYO group performed 240 jumps over four sessions (60 jumps per session). After the eight-week intervention, all players underwent a one-week detraining period with no PT training while basketball training and competitions continued. Testing was performed at baseline (pre-test), after intervention (post-test), and after the detraining period. Players were assessed for lower body power using jump tests (countermovement jump \[CMJ\], drop-jump \[DJ\] from a 20-cm box, and horizontal jump \[HJ\]; change of direction ability using a planned agility test; and speed using a 20-m sprint and a 5-m split.

Outcome Measures

Primary Outcomes (1)

  • Horizontal jump

    Players performed two jumps for each protocol, with one minute of rest provided between trials and three minutes of rest between protocols. The best result was recorded for analysis. In the HJ, a metric tape was used to measure the length between the players' starting position and the nearest point of landing contact (i.e., the back of the heels). The players begin standing with their toes positioned against a marker. Players initiated the jump with countermovement and arm swing, jumping horizontally as far as possible and landing on both feet. The jump was invalid if the players did not land properly on their feet or fell back.
