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 found that women’s muscles recovered just as well after a second round of intense exercise, no matter where they were in their cycle or if they took birth control, 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.

Your muscles learn to handle hard eccentric moves quickly—after just 10 weekly sessions, they stop getting damaged even if you do them at max effort.

Your muscles get used to tough workouts over time, so they hurt less and recover faster the more you do them.

Even if you only train one way—like pushing weights up—your body still learns to handle hard eccentric movements without damage, suggesting the adaptation is whole-body, not just local.
