Abstract

This study aims to analyze the relationship between leg muscle power, arm muscle power, and anthropometry with the speed of the ball resulting from an open spike in athletes from the Sumedang Integrated Indonesian Volleyball Generation School. The study used a quantitative approach with a correlational method. The sample consisted of 21 athletes, with leg muscle power measured using the Vertical Jump Test, arm muscle power measured using an 8-second push-up test, and anthropometric data obtained through Karada Scan. The speed of the open spike ball was measured using a Speed Radar Gun. The data were analyzed using descriptive statistics, normality tests, Pearson or Spearman correlations, and multiple regression with a significance level of p < 0.05. The results showed that arm muscle power, height, weight, and body muscle mass were significantly related to ball speed, while several other variables such as leg power (Spearman), leg muscle mass, and BMI showed no significant relationship. Multiple regression analysis shows that the three independent variables simultaneously contribute 45.4% to ball speed. This finding confirms that spike performance is the result of an interaction between muscle strength and anthropometric characteristics. This study recommends a training program that focuses on strengthening the arm muscles, developing core strength, and managing body composition to improve spike speed in volleyball athletes.

Abstract

This study aims to explore the relationship between coach-athlete relationships and achievement motivation in football players. This research is based on the significance of quality interaction between coaches and athletes as a psychological element that influences motivation, satisfaction in training, and athletic performance. This study applied a quantitative method with a descriptive correlational design, involving 40 football athletes from the Indonesian University of Education's Student Activity Unit Football. The measurement tools used include the Coach-Athlete Relationship Questionnaire (CART-Q) to assess commitment, closeness, and complementarity, as well as the Sport Motivation Scale II (SMS-II) to measure six aspects of motivation. Findings from descriptive analysis indicate that the level of coach-athlete relationships is high and consistent across all dimensions of CART-Q. Motivation evaluation shows the dominance of autonomous motivation, reflected in high scores on intrinsic motivation, integrated regulation, and identified regulation, with low levels of amotivation. Pearson's correlation test revealed a positive and significant relationship between coach-athlete relationships and achievement motivation (r = 0.438; p < 0.01). These findings imply that the better the quality of the relationship formed between coaches and athletes, the greater the athletes' motivation to achieve. This study confirms that a high-quality coach-athlete relationship serves as a crucial factor in building achievement motivation, so coaches are expected to improve communication, trust, and emotional support during the coaching process.

Abstract

Self-control is a fundamental psychological aspect relevant to the context of martial arts. Research on the factors that simultaneously influence it in pencak silat remains limited. This study aims to examine differences in self-control based on belt level, gender, and training duration among practitioners of pencak silat from the Persaudaraan Setia Hati Terate (PSHT). A quantitative approach with a comparative design and cross-sectional method was used in this study. The sample consisted of 62 active members of PSHT Sukasari in Bandung City, selected through purposive sampling. Self-control was measured using the 10-item Brief Self-Control Scale (BSCS), which covers the dimensions of inhibition and initiation. Data analysis was performed using one-way ANOVA and the independent samples t-test with the aid of SPSS 26.0. The results of the study showed significant differences based on belt level in the inhibition dimension (F = 2.790; p = .048; η² = 0.126), with the mori belt group achieving the highest mean score. Training duration showed significant differences in the inhibition dimension (F = 5.656; p = .002) and the initiation dimension (F = 3.179; p = .031), with a trend toward increased self-control as training duration increased. Gender did not show significant differences in either dimension (p > .05). It was concluded that the duration of training plays a more significant role in shaping the self-control of pencak silat practitioners than gender.
