Human growth hormone responses to sprinting

A number of studies have shown exercise to stimulate human growth hormone (hGH) secretion, although most of these have considered prolonged submaximal or resistance exercise. Only a few have studied maximal sprint exercise, and these studies have demonstrated considerably elevated circulating hGH concentrations during recovery. However, there is little agreement in the literature regarding the regulation of hGH secretion during and after exercise. This thesis describes a series of experiments considering the hGH response to sprint exercise, with the intention of gaining a better understanding of some of the mechanisms involved in regulating the exercise-induced hGH release.
