Differences In Strike Index Between Treadmill And Aquatic Treadmill Running In Experienced Distance Runners, James Paul Hoover Jr.

Strike index (SI) quantifies how one’s foot contacts the ground at the beginning of the stance phase of gait. SI is reported as a percentage of the total foot length, with lower percentages indicating a more posterior point of contact, while greater percentages indicate a more anterior point of contact along the foot. Differences in SI may be related to running-related injuries, such that experienced distance runners who are rearfoot (posterior) strikers may have approximately twice the rate of repetitive stress injuries than forefoot (anterior) strikers. Previous research has shown that forefoot strikers, as opposed to rearfoot strikers, produce lower …
