The Claim
The repeated bout effect provides robust protection against eccentric exercise-induced muscle weakness in recreationally active females aged 18–30, demonstrated by complete recovery of maximal voluntary contraction torque within 48 hours following a second bout of 150 maximal eccentric contractions of the elbow flexors performed four weeks after the initial bout, with no influence from menstrual cycle phase or oral contraceptive use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
See the scientific wording
The repeated bout effect (RBE) provides robust protection against eccentric exercise-induced muscle weakness in recreationally active females aged 18–30, as evidenced by complete recovery of maximal voluntary contraction (MVC) torque within 48 hours after a second bout of 150 maximal eccentric contractions of the elbow flexors performed four weeks after the initial bout, regardless of menstrual cycle phase or oral contraceptive use.
What the research says
1 studyThe 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.
