Book Description
Plyometrics has shown significant improvements for explosive power, strength, and body composition. Purpose. The purpose of this research study was to examine the effects on power in a land plyometric exercise program. It is important to note the issues for different effects on power when performing plyometrics in a periodized program in comparison to not participating in one. Methods. The study had 13 participants (10 males: 23.44.01 years, 3 females: 21.332.52 years), which were randomly selected to land plyometric training (LPT; n=6; 5 males, 1 female) or a CG (n=7; 5 males, 2 females). The study consisted of a pre-test, 8-week intervention, and a post-test the 10th week. Participant's vertical jump height (VJH), hang time, body composition, and physical activity enjoyment scores were recorded. A repeated measures ANOVA was utilized to determine between and within groups differences and Cohen's d was used to calculate effect sizes. The current study researched quantitative data to find statistical evidence for VJH. This study outperformed previous research in VJH with similar age groups, while younger participants in previous research outperformed the LPT group. Results. A significant effect over time was found for all groups in VJH (p= .045). LPT increased their VJH by a mean of 1.2 in (7.06%) and CG by 0.4 in (1.88%). Hang time also increased significantly over time among both groups (p= .032). LPT slightly decreased body fat percentage with a small negative d = .04, but this data was not significant (p= .080). Conclusion. The current study provides significant evidence for LPT being an effective method for increasing VJH over time but found no significance for time and group interactions. It should be noted the researcher could not control exercise participation outside of the research study, which could have confounded results. The fitness levels and age can also have an impact on increasing VJH. Future research should seek different training environments, increased sample size, and length of study.
