Peak lower-limb acceleration in collegiate distance runners over varying surfaces

Peak lower-limb acceleration (PLA) is a possible factor influencing tibial stress fractures in runners . The majority of training runs are performed over varying surfaces and at lower intensity . This study evaluated differences in PLA across road and woodchip trail surfaces during a typical training run in collegiate distance runners. Inertial measurement units were used to quantify PLA over road and woodchip trail surfaces. The results indicate that males and females may adjust their running patterns differently for different surfaces.
