runner's highHesFit.com, our men’s health and fitness partner site, recently reported that runner’s high was largely caused by the presence and production of endorphins in the human body. Interestingly enough, it turns out this issue isn’t as cut and dry as it may seem. Recent research questions the role of endorphins in the onset of runner’s high and turns instead to other factors to explain this state of temporary euphoria.

Endorphins are hormones, recognized for their morphine-like qualities, that are produced in your body during exercise. As Dr. Owen Anderson in Runner’s World magazine was quoted as saying, it is “[s]tress, either emotional or physical [that] triggers the release of endorphins into the bloodstream.” Intense physical activity, an undeniable cause of stress on the body, is widely recognized as the main trigger in this release of hormones.

The only change in sexual function was a decreased volume of semen.

pills-2.jpgSome athletes take estrogen blockers and human chorionic gonadotropin (Journal of Clinical Endocrinology & Metabolism 2006), which have not been banned by sports authorities such as the Olympic committee.

Estrogen blockers such as Tamoxifen, Arimidex, Aromasin, and Femara are used to treat women with, or at high risk, for breast cancer. Evidently lowering the female hormone, estrogen, may act the same way as raising the male hormone, testosterone, to help athletes recover faster from hard workouts.
