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.

Growth hormone responses to treadmill sprinting in sprint- and endurance-trained athletes

Cross-Sectional Study

Human

1996

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.

Similar Assertions

Doing really intense sprints gives your body a big, quick boost in growth hormone—up to 17 times more—which helps protect your muscles and burn fat.

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.

Even if your muscles get a big burst of growth hormone right after lifting weights, that doesn’t mean you’ll grow bigger muscles over time—some people who got way more of this hormone didn’t grow more muscle than others.

Even though lifting weights with short breaks makes your body release more growth hormone, that doesn’t mean you’ll grow bigger muscles over time.
