Step Frequency and Lower Extremity Loading During Running

International Journal of Sports Medicine, 04/13/2012

The authors found that there were significant differences in lower extremity loading variables among 5 step frequency conditions. Furthermore, quadratic regression analyses revealed that the minimum loading variable frequencies were 17.25, 17.55, and 18.07% of preferred step frequency for vertical impact peak (VIP), vertical instantaneous loading rate and VIAR, respectively. Thus, adopting a step frequency greater than one's preferred may be practical in reducing the risk of developing a tibial stress fracture by decreasing lower extremity loading variables.
