Abstract

Background of study: This study, conducted in 2021, aimed to develop and evaluate the “Jimax” hook punch training model supported by an Android-based application for boxers aged 16–30 years. Methodology: The research employed the Research and Development (R&D) method adapted from Borg and Gall. The participants were amateur and professional male boxers in Jakarta within the age range of 16–30 years. The small-scale trial involved 20 athletes from two boxing clubs, while the large-scale trial included 40 athletes from four clubs. Furthermore, the effectiveness test was carried out with 20 athletes in the experimental group and 20 athletes in the control group. The instrument used in this study was the basic hook punch technique. Results: The findings revealed 16 variations of the “Jimax” hook punch training model for boxers aged 16–30 years. The mean N-Gain Score of the experimental group was 0.4078, categorized as moderate, whereas the control group scored 0.1194, categorized as low. The mean difference between the experimental group (9.84) and the control group (3.35) was statistically significant, with a t-value of 8.616, df = 38, and a significance level (2-tailed) of 0.000 < 0.05. Conclusion: Therefore, the “Jimax” training model is proven to be more effective in improving hook punch skills compared to conventional training models.
