HGH released naturally during sprinting

In a new study, researchers compared HGH growth hormone levels in several ways — resting (for a baseline measurement), after a 6 second cycle sprint, and after 30 second cycle sprint. Researchers also measured growth hormone for hours afterwards to see how long HGH stayed in participant’s bodies after exercise, (The time course of the human growth hormone response to a 6 second and a 30 second cycle ergometer [an indoor rowing machine that measures the amount of energy or work performed] sprint, 2002, Stokes).

The 6 second sprint method did move HGH some, but didn’t come close to the body’s potential to release this powerful hormone. The 30 second all-out effort sprint experiment increased HGH by 530% over resting baseline and 450% over the lesser intensity sprint.

Like earlier research studies, HGH stayed elevated for 1.5 to 2 hours after the sprinting program. And according to the researchers at the University of VA, the HGH released during exercise targets body fat for up to two hours after training. (Impact of acute exercise intensity on pulsatile growth hormone release in men, 2000, Pritzlaff).

HGH may be the most powerful fitness improving, anti-aging (and anti-middle-aging), body fat reducing, muscle toning, hormone in your body. And the fitness hormone can be increased by 530% with specific types of anaerobic fitness training. Natural is almost always better. And increasing the fitness hormone naturally through exercise is the natural choice!
