The Claim
In young men, six weeks of sprint training does not significantly alter resting serum growth hormone concentrations, indicating that the training-induced reduction is specific to the exercise-induced growth hormone response.
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.
Sprint training for six weeks does not change the amount of growth hormone in the blood of young men when they are at rest. This means the training only affects the growth hormone that spikes during exercise, not the normal level.
See the scientific wording
Resting serum growth hormone concentrations do not significantly change following six weeks of sprint training in young men, indicating that the training-induced reduction is specific to the exercise-induced hGH response.
After six weeks of sprint training, the body gets better at clearing waste products like ammonia that build up during intense exercise. Because ammonia is one of the chemicals that tells the brain to release growth hormone, less ammonia means a smaller growth hormone spike after sprinting. But when you're resting, there's no extra ammonia, so growth hormone levels stay the same as before training.
What the research says
1 studyStudy: Effect of 6 weeks of sprint training on growth hormone responses to sprinting
After six weeks of sprint training, the growth hormone level in your blood at rest stays the same, but the big spike that happens right after sprinting gets much smaller.
