Abstract

This study investigates the effectiveness of functional insoles on plantar pressure distribution during race walking in order to reduce the high plantar pressure and force on race walkers, who tend to suffer from overuse injury. A total of 20 male race walkers were recruited as subjects. Each participant completed a race walk with and without functional insoles. Plantar pressure insoles were used to collect plantar pressure data. A two-way analysis of variance with a mixed design was used to determine the difference between the two conditions. Results show that the use of functional insoles reduced the peak pressure and the impulse in the metatarsal heads and heels and thus suggest that functional insoles reduce the overuse injury risks of these parts. The first ground reaction force peak also decreased. This result suggests that functional insoles reduce the risks of foot and leg injuries.
