The Claim
In healthy young men, higher self-reported dominance is associated with lower mean heart rate during a single sprint interval exercise session (5 × 10-s all-out with 50-s recovery), but dominance is not associated with changes in testosterone or cortisol in response to the exercise.
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 healthy young men, those who say they are more dominant tend to have a lower average heart rate during a specific type of high-intensity interval workout, but being more dominant does not change the levels of two stress-related hormones (testosterone and cortisol) during that workout.
See the scientific wording
In healthy young men, higher self-reported dominance is associated with lower mean heart rate during a single sprint interval exercise session (5 × 10-s all-out with 50-s recovery), but dominance is not associated with changes in testosterone or cortisol in response to the exercise.
When a person feels more dominant, they feel more confident and less threatened during intense exercise. This calms the body's alarm system, so the heart doesn't beat as fast. Meanwhile, the levels of stress hormones like cortisol and testosterone stay the same because the body's hormone-producing glands are not affected by dominance.
What the research says
1 studyMen who think they are more dominant had lower heart rates during the sprints, and their testosterone and cortisol levels didn't change based on dominance, which matches the claim.
