The Claim
In trained athletes, peak power output and peak blood lactate concentration collectively account for 82% of the variation in peak serum growth hormone response during maximal sprinting, demonstrating a strong association between anaerobic performance markers and growth hormone release.
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.
When athletes do their hardest sprints, how fast they go and how much lactic acid builds up in their blood can explain most of why their growth hormone spikes — it’s closely tied to how intensely their body is working.
See the scientific wording
Peak power output and peak blood lactate concentration together explain 82% of the variation in peak serum growth hormone response during maximal sprinting in trained athletes, indicating a strong association between anaerobic performance markers and GH release.
What the research says
1 studyStudy: Growth hormone responses to treadmill sprinting in sprint- and endurance-trained athletes
The study found that how hard someone sprints and how much lactic acid builds up explains most of the increase in growth hormone, just like the claim says.
