Abstract

This study aimed to determine the effectiveness of the push-up training method on the speed of the jodan zuki punch among Shorinji Kempo kenshi at the Gorontalo State University Dojo. The research employed a quantitative approach using an experimental method with a one-group pretest-posttest design. The sample consisted of 12 male kenshi selected through purposive sampling based on the criteria of being active practitioners and registered athletes. The research instruments included a handbox as the punching target and a stopwatch to measure the number of jodan zuki punches performed within 10 seconds. The push-up training program was conducted for six weeks with a frequency of three sessions per week, totaling 18 training sessions. Data were analyzed using descriptive statistics, the Shapiro–Wilk normality test, and hypothesis testing through the Paired Samples t-Test at a significance level of 0.05. The results showed that the mean speed of jodan zuki punches increased from 13.08 in the pre-test to 16.25 in the post-test, representing an improvement of 3.17 points or 24.24%. In addition, the standard deviation decreased from 2.81 to 2.52 and the variance decreased from 7.90 to 6.38, indicating greater homogeneity and consistency in athletes’ performance after completing the training program. The hypothesis testing results confirmed that the push-up training method had a significant effect on improving the speed of jodan zuki punches. Therefore, push-up training can be recommended as an effective, simple, and economical physical training method for enhancing punching performance in Shorinji Kempo athletes.

Abstract

This study aimed to analyze the relationship between lower limb muscle power and the frequency of roundhouse kicks among male MMA Pogogul athletes in Buol Regency, Central Sulawesi. The study employed a quantitative method with a correlational approach. The population consisted of all male MMA Pogogul athletes in Buol Regency, totaling 9 athletes, all of whom were selected as the research sample using a total sampling technique. Lower limb muscle power was measured using the Standing Broad Jump test, while roundhouse kick frequency was assessed based on the number of kicks performed within 10 seconds. Data were analyzed using descriptive statistics and the Pearson Product-Moment Correlation test. The results revealed a correlation coefficient (r) of 0.624, indicating a positive relationship between lower limb muscle power and roundhouse kick frequency. These findings suggest that athletes with greater lower limb muscle power tend to perform roundhouse kicks at a higher frequency. However, the observed correlation did not reach statistical significance at the 5% significance level, as the calculated r value was lower than the critical r value. The coefficient of determination was 38.94%, indicating that lower limb muscle power contributed 38.94% to the variation in roundhouse kick frequency, while the remaining 61.06% was influenced by other factors, such as movement coordination, balance, flexibility, technical proficiency, and neuromuscular ability. Based on the findings, it can be concluded that lower limb muscle power has a positive relationship with roundhouse kick frequency, although the relationship is not statistically significant. These findings indicate that roundhouse kick performance is a multifactorial skill influenced by various physical and technical factors that interact simultaneously. Therefore, efforts to improve roundhouse kick performance should not only focus on enhancing lower limb muscle power but should also incorporate technical training, movement coordination, balance, flexibility, and speed endurance training.
