The Claim
In trained men, resistance training to muscular failure does not result in greater subjective fatigue or elevations in creatine kinase and lactate dehydrogenase biomarkers compared to submaximal resistance training, regardless of training proximity to failure.
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 trained men, lifting weights until muscle failure produces the same levels of perceived tiredness and muscle damage markers as lifting weights without reaching failure.
See the scientific wording
Subjective fatigue and biomarkers of muscle damage (CK and LDH) show no meaningful differences between resistance training groups with varying proximity to failure in trained men, suggesting that training to failure does not significantly increase acute or longitudinal fatigue beyond submaximal training.
In trained muscles, repeated stress from heavy lifting triggers internal systems that prevent excessive damage and fatigue, no matter how close to failure the workout goes. These systems keep muscle cell breakdown and fatigue signals under control, so the body doesn't react more strongly to pushing harder.
What the research says
1 studyIn trained men, lifting weights until muscle failure didn’t make them feel more tired or cause more muscle damage than stopping a few reps short. The study found no meaningful difference in fatigue or muscle damage markers between the two approaches.
