A Comparison of Foot Plantar Pressure in Badminton Players with Normal and High-Arched Feet during the Two-Way Lunge

Background: Compared to the individuals with a normal arch structure, those with high or low arch can be at an increased risk of overuse injuries. The risk of overuse injury among athletes is high due, in part, to the repeated loading of the lower extremities. The current study aimed to determine if foot type (high-arched or normal) results in differences in plantar pressure during two badminton-specific movements (right-reverse lunge and right-lateral lunge). Methods: Twenty badminton players (10 with normal feet and 10 with higharched feet) completed five trials in both right-reverse and right-lateral lunge, while in-shoe pressure data were collected at 100 Hz. The peak pressure and mean pressure were analyzed among the subjects for five major anatomical regions of the foot, using the independent t test in SPSS version 20. The foot type was determined by the foot posture index (FPI) (α
