The Claim
Sprint-trained athletes exhibit a significantly higher peak serum growth hormone (GH) response following a maximal 30-second treadmill sprint compared to endurance-trained athletes, with mean peak GH levels of 72.4 mU/L (SEM 12.5) versus 26.3 mU/L (SEM 4.9), indicating that training specialization is associated with differences in acute hormonal responses to high-intensity 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.
Sprint athletes get a much bigger spike in their growth hormone after a hard 30-second sprint than endurance athletes do — their bodies react differently because of their training.
See the scientific wording
Sprint-trained athletes exhibit a significantly higher peak serum growth hormone (GH) response to maximal 30-second treadmill sprinting compared to endurance-trained athletes, with mean peak GH levels of 72.4 mU/L (SEM 12.5) versus 26.3 mU/L (SEM 4.9), respectively. This suggests that training specialization is linked to differences in acute hormonal responses to high-intensity exercise.
What the research says
1 studyStudy: Growth hormone responses to treadmill sprinting in sprint- and endurance-trained athletes
The study tested sprinters and endurance athletes doing a 30-second all-out sprint and found sprinters had much higher growth hormone levels, just like the claim says.
