Rafting is a branch of water sports that requires arm muscle strength, coordination, and physical endurance to face strong river currents. Arm muscle strength is a major factor in producing effective rowing power, boat stability, and overall team speed and rhythm. This study aims to analyze the level of arm muscle strength of rafting athletes in Semarang Regency. This study uses a qualitative descriptive method with a cross-sectional approach. The sample of this study is 18 Semarang Regency raft athletes with a total sampling technique. This research instrument uses a hand grip dynamometer to measure the strength of the right and left arms. Data were analyzed descriptively using SPSS. The results showed that the average right arm strength of all athletes was 37.2 kg, while the left arm was 32.8 kg, with an average difference of 4.4 kg (11.8%). Based on the strength category, 11.1% of athletes were in the very strong category, 38.9% in the strong category, 33.3% in the medium category, and 16.7% in the weak category. The conclusion in this study is that most rafting athletes have excellent arm muscle strength.
