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.
