Abstract: This study aimed to analyze the contribution of leg length, leg muscle strength, arm span, and maximum oxygen volume of athletes to the performance of 100-meter crawl style swmming, and how significant the contributions were. This study employs a descriptive and correlational research method. Specifically, this research focused on 40 Pandhowo Swimming Club female athletes with an age range of 12-13 years old. In this study, there are four independent variables: leg length, leg muscle strength, arm span, and maximum oxygen volume. While the performance of the 100-meter crawl style swimming is used as the dependent variable. This study collected data through tests and measurements of each variables, and the analysis is done using correlation technique, which tests normality, linearity, and hypotheses Results indicated that leg length, leg muscle strength, arm span, and maximal oxygen volume contributed significantly to the performance of the 100-meter crawl style swimming. The effective and relative contribution of each variable is as follows: leg length has an effective contribution of 15% and a relative contribution of 20%, leg muscle strength has an effective contribution of 20% and a relative contribution of 30%, arm span has an effective contribution of 6% and a relative contribution of 9%, and maximal oxygen volume has an effective contribution of 25% and a relative contribution of 38%.

Keywords: Crawl, contribution, intermediate.
