Growth Hormone and Exercise

Posted Nov 17 2008 9:11pm

In response to the comments about sprinting, I looked further into the relationship between growth hormone(GH) release and exercise.  In terms of sprinting, I found that that the average peak serum GH concentration from a single 30 second sprint was between 10 and 20 ug/L.

In terms of resistance exercise, I found that the average peak serum GH achieved during acute resistance exercise was between 5 and 25 ug/L.  Similarly, the average peak serum GH achieved during acute aerobic exercise is also between 5 and 25 ug/L.

So it appears that either high-intensity sprinting or high-intensity resistance work can lead to similar increases in growth hormone.  Looking at other papers, I found that the growth hormone response to high-intensity exercise decreases somewhat with training.
