Abstract

This study aims to determine the effect of core stability exercises (Elbow Plank, High Plank, and Elbow Plank With Legs Open) on abdominal muscle strength and balance.  Quasi-experimental research and research design using nonequivalent control group design. The purposive sampling technique was used in this study to determine the research subjects where the total research subjects obtained 32 people. The research instruments used were the sit up test (30 seconds) to measure abdominal muscle strength and the standing stork test to measure balance. The results of the manova test showed that there was a significant difference, while the post hoc test showed that the results did not have a significant difference in influencing abdominal muscle strength and balance. The results of plank training showed a significant difference, both in abdominal muscle strength and balance. The conclusion of this study is that the plank core stability variation training method has a more significant effect on increasing abdominal muscle strength and balance.

Abstract

This research problem in volleyball requires quick decision-making and solid teamwork, but many training programs still focus on physical and technical aspects, neglecting the development of structured psychological skills integrated with character building. This study aims to test the effectiveness of structured psychological skills training (PKP) in improving mental readiness, performance-related abilities, and character building in volleyball athletes. A total of 38 volleyball athletes participated in an eight-week PS program (three times/week) that included visualization, stress management, and goal setting. A quantitative experimental design was used with pre-test and post-test measurements using a modified Psychological Skills Inventory for Sports (PSIS). Data analysis used the Wilcoxon test and Spearman's correlation. The results of the study showed a significant increase in motivation, self-confidence, mental preparation, and emphasis on teamwork (p < 0.05). In addition, a significant positive correlation was found between intelligence and mental preparation (p=0.021), as well as cooperation and self-confidence (p=0.029). These improvements indicate that psychological interventions are effective in strengthening the cognitive-motivational aspects of athletes. The relationship between intelligence and cooperation with psychological skills confirms that cognitive abilities and social character contribute to athletes' mental toughness. In conclusion, structured PKP has been proven effective in improving the mental readiness and collaborative character of volleyball athletes. The systematic integration of psychological training into athlete development programs is highly recommended.
