In this research, we aim to investigate the influence of the difference of the foot direction at the time of cutting maneuver on the knee joint motion and to help prevent sports injuries in badminton.

Calculation items are knee flexion, valgus, internal rotation angle, maximum vertical ground reaction force. The analysis section is the stop period from the foot contact to the maximum knee flexion position and the movement period from the maximum knee flexion position to the toe-off. Foot contact is defined as the point when the vertical ground reaction force exceeds 10 N, and the toe-off is defined as the point when the vertical ground reaction force falls below 10 N. The analysis section is normalized to 100%.
All evaluations are performed three times, and an average value of three times is used as a representative value of the object for analysis.

Behavior,custom |
The task operation holds the racket, steps backward, and turns back to the original direction. Cut the foot with both legs, after overhead stroke, landing on the ground reaction force plate set at the distance of 80% of the height behind the body with a non-dominant hand lower leg and instructing it to switch back to the start position as soon as possible. Control condition that does not regulate the orientation of the foot part when touching the ground.
Take the neutral condition to direct the foot to the front when touching the ground.
Take the toe-out condition to turn the foot 45 degree outward when touching the ground.
