The purpose of this study is to determine the effect of windmill arm exercises on 50-meter freestyle swimming speed. Methods. This research used an experimental method with a one-group pre-test-post-test research design. Sampling used a total sampling technique with 45 junior swimmers as participants. The data collection method used the 50-meter freestyle swimming test in both the pre-test and post-test. This research used the t-test for analysis. Results. Based on the results of this research, the calculated t-value is 20.364. This t-value (20.364) is compared to the critical value of t (2.000) at a significance level of α = 0.05 with a degree of freedom df = n − 1 = 44. Thus, tht_hth (20.364) > ttt_ttt (2.000), and based on the table for α = 0.05, a significance level of 0.05 is obtained. This indicates a significant effect on improving the 50-meter freestyle swimming speed of the sample group. Conclusions. Thus, the null hypothesis (H0) is rejected, and the alternative hypothesis (Ha) is accepted. Findings. The alternative hypothesis (Ha) states that windmill arm exercises affect 50-meter freestyle swimming speed in junior swimmers. © 2024, DJ Studio. All rights reserved.
