|THE EFFECT OF PLYOMETRICS TRAINING AND ACHIEVEMENT MOTIVATION TOWARDS LEG MUSCLE EXPLOSIVE POWER OF VOLLEYBALL ATHLETES IN UNIVERSITAS NEGERI PADANG|
|Plyometrics Training, Motivation, Explosive Power of Leg Muscle|
Objectives: The objective of this study is to determine the differences of plyometrics training using knee tuck jump and box jump and achievement motivation towards leg muscle explosive power of volleyball athletes in Universitas Negeri Padang. Methods: The specific objective of this study is to determine the differences in the level of leg muscle explosive power ability between four groups of athletes who were treated differently. It was an experimental studyusing by level 2x2 designs. There were 75 males volleyball athletes of UNP taken as the population.. The sampling technique used was total sampling. The techniques of data collection used wereinstruments of leg muscle explosive power andachievement motivation. The technique of data analysisused was two ways analysis of variance (ANOVA) at the level of 5% (α 0.05) and Tukey test. Results: The result shows that: (1) the leg muscle explosive power of the athletes trained by knee tuck jump was better/higher than those who were trained by box jump plyometrics, (2) there was interaction between the methods of training and achievement motivation towards leg muscle explosive power of volleyballathletes, (3) the explosive power of leg muscle trained with knee tuck jump plyometrics was better than box jump training on a group of athletes whose high achievement motivation (4) there was difference explosive power ofleg muscle performed by low achievement motivation athletes trained with knee tuck jump and box jump plyometrics. Conclusion: Plyometrics training supported by achievement motivation will influence the leg muscle explosive power of volleyball athletes.
