Sepak takraw involves explosive jumping movements, so leg muscle power plays a very important role. Analyzing leg muscle performance with the jump power meter (JPM) application will make it easier to analyze data, but analysis with JPM has not yet been carried out. This study aimed to analyze the leg muscle power profile of sepak takraw athletes using the Jump Power Meter (JPM) test instrument, as well as to determine the correlation mechanism between body weight, jump height, gender, and power performance variables. This study is a quantitative descriptive cross-sectional study involving 88 sepak takraw athletes (46 males and 42 females). Purposive sampling was used to select participants. The research instrument was a Jump Power Meter (JPM), which can measure jump height, body weight, power (in watts), and power (in kg.m/s). SPSS version 23 was used to aid with data analysis procedures such as category mapping, the Mann-Whitney difference test, and the Spearman-Rho correlation test. The data suggest that the majority of male athletes (39.13) and female athletes (35.71) fall into the fair and poor category. The female group had a lower average power (watts) than the male group, which was 12.74 watts. Jump height and power (watt) have a positive correlation (r=0.821) with a significance level of 0.000 < 0.05. Body weight and power (watts) have a positive correlation (r=0.735), with a significance level of 0.000 < 0.05. There is a strong correlation between power (in watts) and power (in kg.m/sec) (r=0.984) with sig 0.000<0.05. These findings have practical implications for coaches to implement digital-based physical monitoring and improve the foundation of strength training, as well as specifically monitored power training. © 2026 by the authors.
