Abstract

This study used new insole pressure technology to examine how movement strategies during approach and exit phases affect change of direction (COD) times. Participants (n=26) wore NURVV smart insoles and performed 90˚ cuts off each leg (dominant [Dom] and non-dominant [ND]). Ground contact time (GCT), cadence, centre of pressure, and return to linear sprinting metrics were analysed for four steps about the cut-step. Faster cadence and a more forefoot strike pattern predicted 58% of the variance in Dom side COD ability. ND COD ability was predicted by a faster cadence immediately post-cut and a quicker GCT two steps before the cut-step (66% of variance explained). These findings emphasize the approach phase’s crucial role in COD ability and stress the need to examine multiple steps around the cut-step for a complete understanding of COD mechanisms.
