It was hypothesized that VJ height would be enhanced through CT and even greater increases would occur as a result of higher intensity resistance exercise. Twenty male high school basketball players were divided into two training groups: a H1 (high intensity), low repetition group and a medium intensity, HR (high repetition) group. Each training group trained twice per week for six weeks. Training protocols involved three sets of 8-10 squat repetitions (80%-85% 1RM (repetition maximum)) for the HI group followed by ten countermovement jumps and thre.e sets of 12-15 squat repetitions (60%-70% 1RM) for the HR group followed by ten countermovement jumps. A three minute rest period was utilized between each set. Participants were tested at weeks 1, 3, and 6. The results of this study revealed that there was not a significant difference between the two CT protocols with respect to VJ (p = 0.077). At week 6 both groups increased VJ significantly; HI group (4.0 ±1.8 cm, p 〈 0.01) and the HR group (2.7 ± 1.6 cm, p 〈 0.01). Within the parameters of this study CT with either HI or HR protocols are effective at improving VJ.展开更多
