Abstract

This study aimed to determine the effect of service distance variation training on the service accuracy of volleyball extracurricular participants at SMP Negeri 45 Medan.

Materials and Methods:

This study employed a quasi-experimental method using a One-Group Pretest-Posttest Design. The population consisted of 40 volleyball extracurricular participants from SMP Negeri 45 Medan. Purposive sampling was used to select the sample based on the following criteria: (1) beginner volleyball extracurricular participants aged 13–15 years, and (2) female gender. Sixteen participants met these criteria.

Results:
The results indicate a significant effect of service distance variation training on the overhand service accuracy of the volleyball extracurricular participants at SMP Negeri 45 Medan, with a calculated t-value of 6.245 (exceeding the t-table value of 2.131) and a significance value of 0.000 (less than 0.05).

Conclusions:
Based on the data analysis, description, research results, and discussion, it can be concluded that serving distance variation training has a significant effect on the overhead serve accuracy of the volleyball extracurricular participants at SMP Negeri 45 Medan, with a calculated t-value of 6.245 (exceeding the t-table value of 2.131) and a significance value of 0.000 (less than 0.05).
