Abstract

This study was aimed to determine how gamma waves and motor educability correlate to gymnastics movement performance of West Java gymnastic athletes. The study used quantitative descriptive method with a correlational design. The population and sample of this study were 13 West Java gymnastic youth athletes selected using saturated sampling technique. The instruments used were gymnastic performance tests, motor educability test (IOWA Brace test), and brain wave test using the Emotiv EPOC Wireless helmet. Based on data processing and analysis, the correlation value between gamma brain waves and movement performance was r= -0.620 with a p -value 0.024 0.05, while the coefficient of determination was 0.384, meaning that there was a contribution of  38.4%. It concludes that, there was a negative functional correlation between gamma brain waves and movement performance. The obtained correlational value between motor educability and gymnastic performance was r = 0.646 with a p-value 0.017 0.05 and a coefficient of determination of 0.418, showing that there was a contribution of 41.8%. It implies that that there was a positive functional correlation between motor educability and gymnastic performance. The correlation value of gymnastic performance, gamma brain waves, and motor educability was r = 0.749 with a p-value 0.016 0.05 and coefficient of determination of 0.560, indicating that gymnastic performance was determined by gamma brain waves and motor educability of 56.0%. The results showed that there was a strong correlation and a significant contribution of gamma waves and motor educability to movement performance in gymnastics.

Abstract

The goals of this study is to determine is there a contribution between self-confidence and anxiety on the performance of gymnastic athletes. The population in this study were 105 West Java gymnast athletes. The sample in this study used a random sampling technique, the sample was taken 20% of the population. The instruments used are self-confidence tests (Andrianto, 2016), anxiety (Competitive State Axienty Inventory-2) and gymnastic performance tests (code of points). Analysis of the research data used descriptive statistical analysis techniques and tested the hypothesis by processing data using the statistical product for social science (SPSS) 26 program. The results obtained were: (1) A correlation of r = 0.592 was found with a p-value of 0.005, and a contribution of 35 %. That way there is a significant positive contribution between self-confidence and gymnastic performance. (2) The correlation value is r = -0.597 with a p-value of 0.004 and contributes 35.7%. Thus there is a significant negative contribution between anxiety and exercise performance. (3) The correlation value is 0.663 with a p-value of 0.005 and contributes 44%. That way there is a significant positive contribution between self-confidence and anxiety on gymnastic performance.
