    This study analyzed the relationship between elbow flexion-extension and ball impact velocity during the serve in male tennis players. A quantitative approach was employed using a non-experimental, correlational, and cross-sectional design. The sample consisted of 15 amateur and competitive tennis players, generating a total of 45 records from three serve attempts per participant. Through biomechanical analysis, elbow flexion and extension angles, as well as ball impact velocity, were assessed. After confirming data normality, Pearson’s correlation coefficient was applied. The results revealed a strong negative correlation between elbow flexion and ball impact velocity (r = -0.894; p < 0.05), and a strong positive correlation between elbow extension and velocity (r = 0.850; p < 0.05). It is concluded that elbow biomechanics significantly influence serve performance, and that proper technical execution is a relevant factor for optimizing athletic performance and contributing to injury prevention.
