Abstract

Running research has focues ont he effects of acute strike pattern modifications, specifically to lower extremity joint kinetics and stiffness. Joint stiffness may be related to injury risk in runners. As 75% of runners use a RFS pattern, it is worthwhile to study these runners. The purpose of this tudy was to xamine th eeffects of imposed FFSon ankle and knee joint stiffness before and after a long run in habitual RFSrunners. Ankl eand knee joinst stiffness as well as running economy were measured pre and post fatiguing long run. Ankle joint stiffness was lower during imposed FFS. Knee joint stiffness was higher during imposed FFS. Joint stiffness between strike patterns was independent of fatigue. The RFSpattern yielded better REthan imposed FFSindependent of fatigue. Our findings suggest aht it would not be mechanically or metabolically beneficial for habitual RFSrunners to acutely adopt a FFS.
