Effect of Plyometric Training Model and the Age towards the Reaction Time and the Agility of Muaythai Atheletes

Abstract

This research aims to determine: (1) the effect of upper body and lower body plyometric training models towards the reaction time and agility, (2) the differences in the effect of age (17-20 years old and 21-24 years old) towards the reaction time and agility, (3) the interaction between upper body plyometric, lower body plyometric training models, and age (17-20 years old and 21-24 years old) towards the reaction time and agility. This research was an experimental study. The research design was a "2x2 factorial" design. The number of research samples were 20 muaythai athletes selected by purposive random sampling. To measure reaction time the researcher used the whole body reaction II test and to measure the agility used the Illinois agility test instrument. The data analysis used the MANOVA (multivariate analysis of variance) test with a significance level of 0.05. The results of this research indicate that: (1) there is a difference in the effect of upper body and lower body plyometric training models towards the reaction time of Muaythai athletes with a p significance of 0.000 < 0.05, and there is a difference in effect between upper body and lower body plyometric training models towards the agility of Muaythai athletes with a significance value of p 0.000 < 0.05. (2) There is a difference in the effect of age (17-20 years old and 21-24 years old) towards the reaction time with a significance value of p 0.002 < 0.05, and there is a difference in the effect of age (17-20 years old and 21-24 years old) towards the agility with a significance value of 0.002 < 0.05. (3) There is a significant interaction between the upper body plyometruc, lower body plyometric training models and age (17-20 years old and 21-24 years old) towards the reaction time with a significance value of 0.002 < 0.05, and there is a significant interaction between the training models of upper body plyometric, lower body plyometric and age (17-20 years old and 21-24 years old) towards the agility with a significance value of 0.001 < 0.05.
