Is your stride wide or do you toe a narrow line? The Role of Stride Width in Running Injury and Economy #runchat

A quick search of the literature came up with some recent, quality studies examining stride width and various leg stresses. Coincidentally, a trio of studies conducted at my alma mater, the University of Wisconsin-La Crosse, by Stacey Meardon and colleagues, have demonstrated a relationship between step width and tibial stress and iliotibial band strain, when comparing runners with varying stride widths. Namely, those who exhibited a “crossover” gait style – where one foot lands to the inside of the opposite leg’s previous position – had over 20% greater IT band strain than those with wider (zero to three centimeter) stride widths. While no study has yet to directly associate stride width with injury, they have demonstrated that the narrow stride width puts increased angular stresses on tissue. Here is a comically-simplified diagram explaining those stresses:
