PLYOMETRICS INCREASE JUMPING ABILITY IN ADOLESCENT MALES
Matavulj, D., Kukolj, M., Ugarhovic, D., Tihanyi, J., & Jaric, S. (2001). Effects of plyometric training on jumping performance in junior basketball players. Journal of Sports Medicine and Physical Fitness, 41, 159-164.
This study attempted to assess the effects of plyometric training when it is added to the training of adolescent males (N = 33; 15-16 years) who already can jump very well. Three groups of elite junior basketball players were established: a) a control group that only performed regular basketball training, b) a group that performed plyometrics (drop-jumps) from 50 cm, and c) a group that performed plyometrics from 100 cm. The added training was performed three times per week for six weeks.
Both experimental groups improved significantly in the maximal vertical jump (4.8 cm for the 50-cm group and 5.6 cm for the 100-com group) and rate of force development in the knee extensors. There were no significant differences between the experimental groups in any measure.
Implication. Drop-jump plyometric training could improve jumping height in adolescent basketball players.
