A new study suggests that women pull back on high-impact exercises, such as running, a week before their period is due in order to lessen their risk of knee injuries. While previous research has focused on the biomechanical differences between men and women, this study looked at how the menstrual cycle can affect nerves that control muscle activity.

A team of researchers from the University of Texas at Austin and University of North Carolina at Chapel Hill measured the activity of nerve fibers and the muscles they control around the knees of seven female volunteers, aged between 19 and 35, at various points of their menstrual cycles.

The researchers found that the bundles of nerves in the knee had firing rates that were significantly higher in the late luteal phase, about a week before a woman’s next period, compared to earlier in the menstrual cycle.

The researchers noted that this difference in firing rate could affect the stability of the joint, potentially affecting its susceptibility to injury.
