Sex Differences in Running Are More Complicated Than We Thought

A new study in the Journal of Applied Physiology, from Emily McClelland and Peter Weyand of Southern Methodist University, digs into the nuances on this topic, and finds evidence that different rules apply in short sprints compared to long endurance events. (Ultramarathons, as usual, are yet another story.) This is a particularly interesting finding given the seemingly odd regulations that currently apply to DSD runners such as Caster Semenya, which affect only events between 400 and one mile—the distances at the intersection between sprint and endurance regimes.
