Anaerobic Training: The Key To Peak Fitness For Young Pencak Silat Athletes Aged 13-15

Abstract

Currently, students often face fitness challenges, such as easily experiencing fatigue during physical activities. One type of physical exercise that can improve fitness is anaerobic training. This study aims to obtain empirical data on the effect of anaerobic training on students’ physical fitness. The research was conducted over a two-month period, from August to September 2025. The research method used was a quasi-experimental design with a one-group pretest-posttest model. The subjects of this study were 30 participants from the Pencak Silat extracurricular program at Ar Rasyidul Karim Boarding School. The instrument used to measure fitness was the simulasi asesmen kebugaran kemdikbud. The results showed that the application of anaerobic training significantly affected students’ fitness levels. Based on the t-test results, the calculated t-value was 8.5. This value was then compared with the t-table value at a 5% significance level (α = 0.05) and a degree of freedom (df) of 29, which was 1.699. Since the calculated t-value (8.5) > t-table value (1.699), it can be concluded that there is a significant difference between the pretest and posttest scores. These findings indicate that anaerobic training is effective as a strategy to improve students’ physical fitness.
