The effect of fatigue caused by consecutive jump- landing on plantar pressure characteristics during stance phase of walking in adolescent volleyball players with and without sprain ankle injury

The purpose of this study was to determine the effect of fatigue caused by jump- landing on plantar pressure characteristics during stance phase of gait. 24 adolescent volleyball players with and without a history of ankle sprain injury participated. Maximum Sole Foot Pressure characteristics during stance phase of gait were collected and analyzed by a Pedo Scan device correlating to Formetric before and after the fatigue protocol. No significant difference seen between plantar pressure characteristics of players without a history of unilateral ankle injury, while there was a significant difference in between players with a history of unilateral ankle injury between average pressure on injured ankle and maximum pressure, step duration and the plantar contact area on non-injured ankle. Due to results, it seems fatigue from consecutive jumping and landing protocol in the group with a history of unilateral ankle injuries can increase risk of lower limb injurie in gait.
