Does your period protect your muscles from soreness?
Variations of sex-hormones in reproductive aged females do not impact the repeated bout effect following maximal unaccustomed eccentric exercise of the elbow flexors

Surprising Findings
High estradiol levels during the late follicular phase did not reduce muscle damage or speed recovery compared to low estradiol states.
Previous research suggested estrogen reduces inflammation and protects muscles — so many expected women in high-estrogen phases to recover faster. This study contradicts that idea in the context of eccentric exercise.
Practical Takeaways
Don’t worry about timing your first hard workout to a specific phase of your cycle — you’ll likely get equally sore regardless.

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.
