Does excercising produce human growth hormone?
I heard scientists did tests with a group of guys, they took a sample of their blood measured their level of growth hormone, then had them go sprint, then took a sample of their blood and noticed like a 400% or 500% increase in growth hormone occured. But then went back to normal after an hour or an hour and 1/2. What im asking is it true your body makes growth hormone when you excercise? It uses the growth hormone to make your muscles bigger and repair them correct?
Yes, your body does make Human Growth Hormone when you exercise. However, scientists are unsure of why. HGH does not, I believe, aid in muscle repair.
