Effect of Weekly Plyometric Training Frequency on Youth Female Basketball Players: A Comparison of Two vs. Four Sessions

Players were randomly assigned to a two-times-a-week (2PLYO, n = 15) or four-times-a-week (4PLYO, n = 15) PT group. Both groups performed the same weekly total volume of jumps during PT in addition to regular basketball training and competition. 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.
