The purpose of this study was to determine the relationship between leg muscle strength and self-confidence, arm muscle strength and self-confidence, and leg muscle strength, arm muscle strength and self-confidence with 50-meter freestyle swimming speed. The sample of this study was 30 male students. In accordance with the formulation of the problem and the objectives to be achieved, the research method used in this study is a quantitative method with correlation and descriptive techniques, namely the researcher will see the relationship between one variable and another. Based on the results of the analysis of research data and discussion, it can be concluded that the following research results (a) there is a relationship between leg muscle strength and 50-meter freestyle swimming speed of 3.61 (b) there is a relationship between arm muscle strength and 50-meter freestyle swimming speed of 3.47. (c) there is a relationship between self-confidence and 50-meter freestyle swimming speed of 4.95 which then the relationship between leg muscle strength and arm muscle strength and self-confidence with 50-meter freestyle swimming speed of 14.99. Thus, the stronger the leg and arm muscles, as well as good self-confidence, the better the 50-meter freestyle swimming speed of male students of the Health and Sports Study Program, FKIP Unpatti Ambon.
