Is knee extension strength a key factor in badminton-specific agility among elite players?
Significant inverse correlations were found between knee extension torque normalized to body mass for the leg opposite the racket-holding hand and badminton-specific agility at both 60 °/s and 180 °/s (males at 60 °/s: <i>r<sub>s</sub></i> = -.619; 180 °/s: <i>r<sub>s</sub></i> = -.579; females at 60 °/s: <i>r<sub>s</sub></i> = -.445; 180 °/s: <i>r<sub>s</sub></i> = -.446). In contrast, only the same-side leg at 60 °/s showed a significant inverse correlation (males: <i>r<sub>s</sub></i> = -.413; females: <i>r<sub>s</sub></i> = -.490). Overall, these results show that knee extension strength is crucial for badminton-specific agility among world-class and elite/international-level male and female badminton players. Furthermore, our findings suggest differing demands for force production between the legs on the same and opposite sides of the racket-holding hand.
