The Claim
Men who regularly engage in endurance or strength training have significantly lower mean heart rates during a single session of sprint interval exercise (5 × 10-second all-out bouts with 50-second recovery) compared to non-trained men.
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.
Men who regularly exercise (like running for endurance or lifting weights for strength) have a lower average heart rate during a very intense short workout (five 10-second all-out sprints with 50-second rests) compared to men who don't exercise. This shows their hearts are better at handling intense exercise.
See the scientific wording
Men who regularly engage in endurance or strength training have significantly lower mean heart rates during a single session of sprint interval exercise (5 × 10-second all-out bouts with 50-second recovery) compared to non-trained men, suggesting better cardiovascular efficiency and physiological tolerance to acute high-intensity exercise in trained individuals.
When you exercise often, your heart gets stronger and bigger. This lets it pump more blood with each beat. So during hard exercise, it doesn't need to beat as fast. Also, your body gets better at controlling your heart rate, keeping it calmer. So trained men have slower heartbeats during sprints.
What the research says
1 studyThe study found that men who exercise regularly have lower heart rates during intense sprints than men who don't exercise, just like the claim says.
