Abstract
Strike type is one of the most important factors affecting running mechanics and dynamics. Overally, strike type could alter running mechanics. Several studies show that strike type is associated with differences in running biomechanical parameters like kinematics, kinetics and loading rate. However, plantar pressure distribution has not been evaluated in different strike types. The purpose of the current study was to compare plantar pressure distribution in runners with different foot strike patterns.
twenty novice runners with different foot strike types (10 runners with rear foot strike type (RFS) and 10 runners with fore foot strike type (FFS)) participated in this study. After subjects entrances to the laboratory, they were asked to run at 3/3 m.s-1 on the 14m runway. A footscan (rsscan international) pressure mat was mounted in the middle of the runway. Peak plantar pressure and peak plantar force were calculated and analyzed.
The results of this study showed that peak plantar pressure and peak plantar force in runners with FFS and RFS groups is different. In the FFS group, forefoot regions undergo more loading in comparison with RFS group. In the RFS group, rear fore regions undergo more loading.
According to the result of this study, plantar pressure distribution patterns was different between groups with different strike types. It could be the source of different running related injuries among runners with different strike types. Also, it could be useful for shoe and orthotic professionals to consider these differences in manufacturing their products in prevention of injuries in runners.
