Neuroendocrine System

Exercise Overload and Regeneration
  • A. C. Hackney


The physiological systems of the human body are placed under a great deal of stress during the process of exercise training. Within elite athletes this stress can be of enormous levels because of the volume and intensity of work they perform in their training regimes . When training stress is of an appropriate level then there is a positive adaptation in the human organism and typically physical performance improves. However, the converse can also be true—inappropriate levels of stress can result in negative, maladaptations and declines in physical performance. In the adaptive process to exercise training, it is well known that there is a need for rest and recovery from the stress of training. If this is not allowed, repetitive exposure to what would normally be an appropriate level of stress can become inappropriate in nature. When an inappropriate level of training stress is imposed upon the athlete there is a great likelihood of the athlete developing the “overtraining syndrome”. Once this occurs, physical performance can decline so severely that the athlete’s competitive season may be over.
