ConclusionThe neuroendocrine system plays an integral function in the development and maintenance of muscle tissue. Numerous investigations have confirmed the effects of both aerobic exercise and heavy resistance exercise upon the neuroendocrine system. Although there has been great progress in the area of exercise and neuroendocrinology, many questions regarding hormonal responses to exercise remain unanswered. In particular, there is a need for additional research that will reveal the specific mechanisms by which different exercise protocols induce hormonal responses.
