Relationship between Arm Length, Power Arm Muscles and Power Lemb Muscles on Butterfly Style Swimming Achievement
摘要整理
This study aims to determine the relationship between arm length, arm muscle power and leg muscle power on butterfly swimming performance. This research uses a survey method. Data collection techniques use tests and measurements. The population in this study were swimming athletes aged 12 to 13 years in the Special Region of Yogyakarta Province. The research used was population research with a total of 27 athletes. The main instruments used are the arm length test, arm muscle power test, leg muscle power test and 25 meter butterfly swimming test. The data analysis used is the normality test, linearity test, correlation test and multiple regression analysis test with a significance level of 5%. The results showed that the relationship between arm length and butterfly swimming performance was 0.617, the relationship between arm muscle power and butterfly swimming performance was 0.460, the relationship between leg muscle power and butterfly swimming performance was 0.838 and the relationship between arm length, arm muscle power and leg muscle power on butterfly swimming performance is 0.897. The correlation between arm length is greater than arm muscle power because each athlete's butterfly swimming technique is not the same (how much the elbow bends when the arm is pulled).
