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.

Variations of sex-hormones in reproductive aged females do not impact the repeated bout effect following maximal unaccustomed eccentric exercise of the elbow flexors

Cohort Study

Human

The study looked at women with high and low estrogen levels and found they had similar muscle weakness and soreness after intense arm exercises, just like the claim says.

Similar Assertions

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.

When women work out during the part of their cycle when estrogen is high, they might build more muscle because estrogen helps protect muscles and speed up recovery.
