The Claim
Resistance training to concentric failure is associated with a significant reduction in positive affective response in trained women, as measured by the feeling scale, while trained men show no significant change in positive affective response following the same intervention.
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.
After performing resistance training to muscle failure, trained women report a measurable decrease in positive feelings, while trained men do not show a change in their reported feelings.
See the scientific wording
Resistance training to concentric failure is associated with a significant reduction in positive affective response in trained women, as measured by the feeling scale (p=0.001), while trained men show no significant change (p>0.680), suggesting sex-specific differences in perceptual responses to high-intensity resistance exercise.
When women lift to failure, their muscles produce more metabolic byproducts that trigger stronger signals to the brain, which reduces feelings of pleasure. Men’s muscles produce similar byproducts, but their brains do not respond the same way to those signals.
What the research says
1 studyWhen trained women lift weights until they can't do another rep, they tend to feel worse afterward, but trained men don’t. The study found this difference clearly and reliably.
