Does your period protect your muscles from soreness?

The study tested if hormone levels during a woman's cycle affect muscle soreness and recovery after hard exercise. Some thought high estrogen might help, but it didn’t.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

In young active women, doing repeated rounds of intense arm exercises doesn’t change how muscles handle calcium, so that’s probably not why they get more resistant to soreness over time.
Your muscles get used to tough workouts over time, so they hurt less and recover faster the more you do them.
In young, active women, having higher natural estrogen levels doesn’t seem to protect against muscle soreness or weakness after intense arm exercises — it hits just as hard as when estrogen is low, like in women taking birth control.
Doing a tough arm workout twice, four weeks apart, helps women's muscles bounce back faster the second time—even if they're on birth control or where they are in their cycle.
In young, active women, hormone levels don’t seem to change how well their muscles recover after a tough workout — whether they’re on birth control or not, their soreness and strength come back at about the same rate.
