| Abstract text | INTRODUCTION: Hamstring-to-Quadriceps (H:Q) ratio is a key indicator of knee injury risk in athletes [1]. While badminton lunges create substantial knee loads [2], the relationship between the H:Q ratio and knee joint mechanics during these movements remains unclear [3]. METHODS: Sixteen male collegiate badminton players (20.3±1.2 years) performed isokinetic strength testing (HUMAC-NORM) at 60°/s and 180°/s. Three-dimensional motion analysis of 60-degree sidestep lunges was captured (Motion Analysis Corp., 200 Hz). Knee joint reaction forces were calculated using ANYMOCAP across three axes. Pearson correlations examined relationships between H:Q ratios and joint forces. RESULTS: H:Q ratio significantly correlated with Y-axis (medial-lateral) joint reaction forces (r=0.674, p<0.05), but not with X-axis (r=0.183, p>0.05) or Z-axis forces (r=0.025, p>0.05). Mean H:Q ratios at 60°/s were 0.62±0.08. CONCLUSION: The significant correlation between the H:Q ratio and medial-lateral knee forces suggests its importance in maintaining knee stability during badminton-specific movements. These findings have implications for training program design and injury prevention strategies. [1] Aagaard P, et al. (2018). Am J Sports Med, 26(2), 231-237 [2] Kuntze G, et al. (2010).
