The Claim
In recreationally active females aged 18–30, estradiol levels do not influence the magnitude of the repeated bout effect following 150 maximal eccentric contractions of the elbow flexors, as both normally menstruating females in the late follicular phase and oral contraceptive users exhibit similar reductions in maximal voluntary contraction torque loss and muscle soreness between bouts, with no significant differences in recovery trajectories (p > 0.05).
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.
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.
See the scientific wording
In recreationally active females aged 18–30, the magnitude of the repeated bout effect (RBE) following 150 maximal eccentric contractions of the elbow flexors is not influenced by estradiol levels, as both normally menstruating females in the late follicular phase and oral contraceptive users showed similar reductions in MVC torque loss and soreness between bouts, with no significant group differences (p > 0.05) in recovery trajectories.
What the research says
1 studyThe study found that women with high and low estrogen levels had similar muscle recovery after tough exercise, so estrogen didn’t seem to affect how well their muscles adapted.
