ABSTRACT

Physical exercise for children is essential, so it must be done according to their development. Excessive physical exercise will place an excessive burden on the child, thereby hampering the child's development and not having much effect on the child. Exercises must be done according to the program and the child's age. This research aims to apply plyometric activities, which can create a training model for beginner athletes so that they can practice more patterns as a whole. The research was designed through experimental research. The research subjects were beginner tennis players in Tasikmalaya City, Indonesia and Chirchik, Uzbekistan. The instrument used is the Illinois test, which is used to find agility abilities in beginner athletes. From this study, both groups of beginner athletes from Indonesia and Uzbekistan obtained the results that the sig value was 0.000, so (2-tailed) <0.05, which indicates an influence between the initial variable and the final variable. So, there is a significant influence on the treatment given previously. Furthermore, the results of Cohen's d test indicate that plyometric training had an effect size of 1.84 for the Indonesian sample group, which signifies a very large effect. Meanwhile, the effect size for the Uzbek sample group was 3.52, indicating an extremely large effect size.
