Research on the Effect of Functional Insoles on the Plantar Pressure and Foot Posture of Runners
This study compares differences in plantar pressure distribution,foot posture indexes(FPI)and the rating of perceived exertion(RPE)after healthy runners run 10 km run with and without functional insoles,and explores the practical significance of using functional insoles to improve runners'sports performance and prevent their running-related injuries.Fifteen qualified runners were recruited to complete two 10 km runs and tests on plantar pressure distribution,FPIs and the RPE after running,respectively.The results showed that maximum pressure in the 2nd~5th phalanx area after running 10km with functional insoles was lower than plantar pressure without functional insoles,with a significant difference(P<0.05),that the score of runners'FPIs after running 10km with functional insoles was lower than that without functional insoles,with a significant difference(P<0.05),and that after running 10km,functional insoles had no significant effect on reducing the RPE(P>0.05).The experimental results indicate that functional insoles can effectively maintain the foot posture of runners and reduce the impact force on feet during running.
