Abstract
The purpose of this study was to investigate the effects of plyometric training performed either before or after practice on selected power measurements for NCAA Division I male basketball players.
Sixteen subjects were split into two groups of eight players each. The groups were split up by a matched pairs method, based on preseason estimates of playing time for each player by the coaching staff. All subjects were pretested (Week 0) on four selected measures of power. Each subject was measured on vertical jump, with a no-step and a two-step approach, standing long jump, and the 30-yard (27.3 m) dash.
Members of both groups performed the same plyometric workout, two times per week, for a 7-week period. The before group performed the exercises at the beginning of practice, while the after group performed the exercises at the end of practice. After the 7-week treatment period (Week 8), both groups were tested again to determine if there was a difference in the selected measures of power, between the two groups. The treatment was discontinued after Week 8 due to the game schedule. Subjects were also tested at the end of the season (Week 22) to determine any long-term effects of the different treatments.
Results of a 2 by 3 analysis of variance showed no differences between the before and after groups on the initial four measures of power at Weeks 0, 8, or 22. Significance level was set at .05.
Combined groups' scores showed no significant changes over the course of the season for both vertical jump measures, or the standing long jump. Analysis of the 30-yard (27.3 m) dash times did, however, show a significant decrease over the course of the season. Duncan's Multiple Range post hoc analysis showed Week Oto be slower than weeks 8 and 22.
Due to a lack of significant change in either the Before or After group no conclusions can be drawn about the effect of performing plyometrics either before of after practice. The lack of change in either group, besides the 30-yard (27.3 m) dash times, may have been due to a plateau effect of previous training. All subjects were involved in a 6-week preseason conditioning program prior to the treatment for the present study. This preseason training, which included plyometrics, contributed to an average 8.13 + 6.18 cm increase vertical jump for all subjects. Subjects may have reached a plateau by the time treatment for this experiment began.
The results of this study indicate that there may be no difference in power changes, if plyometrics are performed before or after practice, for athletes who have previously been involved in a plyometric training program.
