Effect of Plyometrics and Resistance Band Training towards the Leg Muscle Power Seen From the Leg Muscle Endurance of Wrestling Athletes

This research aims to determine: (1) the difference in the influence between plyometrics and resistance band training on leg muscle power in wrestling athletes; (2) the difference in effect between wrestling athletes who have high and low leg muscle endurance on leg muscle power; (3) the interaction between plyometrics and resistance band training as well as high and low leg muscle endurance towards the leg muscle power of wrestling athletes.The type of this research was an experiment using a 2 x 2 factorial design. The research population was the wrestling athletes from Malang City, totaling 40 people. The research sample was 24 people taken by using purposive sampling technique, then ordinal pairing was carried out to divide each group. The instrument used to measure leg muscle power was the standing long jump, while leg muscle endurance was measured by using the squat test. The data analysis technique used the two way ANOVA test.The results of the research show that: (1) there is a difference in the effect between plyometrics and resistance band training towards leg muscle power of wrestling athletes where the F value is at 11.674 and the significance value is at p 0.003 < 0.05. The plyometrics training group is better than the resistance band training group with an average difference at 13.92. (2) There is no difference in the effect between wrestling athletes who have high and low leg muscle endurance towards leg muscle power, where an F value of 0.704 is obtained and a significance value of p is at 0.411 > 0.05. (3) There is no interaction between plyometrics and resistance band training and high and low leg muscle endurance towards the leg muscle power of wrestling athletes, where the F value is at 0.402 and the p value is at 0.533 > 0.05.
