Introduction: The importance of physical training in badminton is reflected in the quality of technical and tactical movements in the field, improving the athlete the physical strength enough as support and the level of physical fitness necessary for their sports performance, reducing sports injuries and, mainly, increasing their hitting rates. Objective: Study the effect of functional training on the hit rate in badminton players. Methods: Bibliographic and experimental research methods were used through the ITN badminton technical level test and the functional movement screening system (FMS). The effect of functional training was compared and analyzed considering baseline return quality and functional movement quality of 12 young badminton players. Results: Compared to the pre-test, the mean baseline reaching depth and accuracy statistical score increased significantly after the 8 weeks of functional training (P<0.05); the control group baseline depth and accuracy test score improved slightly but not significantly (P>0.05). Conclusion: Young badminton players who add functional training to physical training demonstrate more relevant impacts on their hitting rates. These exercises have also demonstrated that they can strengthen muscles and increase shoulder, hip, and knee flexibility. Level of evidence II; Therapeutic studies - investigating treatment outcomes.
