Introduction: Currently, compound rapid stretching training has been explored by sports researchers. However, most research focuses on soccer, basketball, volleyball, and other sports that require vertical jump fitness, but little attention is paid to badminton. Objective: Study the influence of compound rapid stretching training on fitness in professional badminton athletes. Methods: By experimental and statistical methods, 16 outstanding college badminton players were randomly divided into composite training and control groups. The sports performance test (T-shaped run) and short-distance mobility test (5-10-5), were evaluated and compared before and after the intervention, adding a specific rapid stretching training protocol to the composite group. Results: Comparatively, the T-run and hexagonal jump tests were significantly improved in the composite group (P<0.01). The time required to complete the 5-10-5 moving test progressed from 3.980s to 3.763s, significantly longer than the control group (P<0.05). Conclusion: 6-week training with rapid stretching was shown to significantly improve the fitness of college badminton athletes.
