The efficacy of arch support sports insoles in increasing the cycling performance and injury prevention

摘要

Genu varum will result in tibia over external rotation and foot supination, which produces a wide oval shape knee sway; in contrast, overpronated foot with genu valgum would produce medial knee excursion during the power phase and lateral sway in the recovery phase which might cause knee and ankle musculoskeletal injury. The arch support insoles could effectively provide knee and ankle dynamic stability during the power phase of cycling which resulting in increasing the muscle power and muscle fatigue.
