Result from excessive strenuous exercise
Overtraining occurs when a person exceeds their body's ability to recover from strenuous exercise. Overtraining can be described as a point where a person may have a decrease in performance and plateauing as a result of failure to consistently perform at a certain level or training load; a load which exceeds their recovery capacity. People who are overtrained cease making progress, and can even begin to lose strength and fitness. Overtraining is also known as chronic fatigue, burnout and overstress in athletes. It is suggested that there are different variations of overtraining, firstly monotonous program over training suggest that repetition of the same movement such as certain weight lifting and baseball batting can cause performance plateau due to an adaption of the central nervous system which results from a lack of stimulation.

A number of possible mechanisms for overtraining have been proposed. One stipulates that microtrauma to the muscles are created faster than the body can heal them. Another proposes that amino acids are used up faster than they are supplied in the diet, a condition sometimes referred to as "protein deficiency". Finally, systemic inflammation has been considered as a mechanism in which the release of cytokines activates an excessive immune response.

Passive recovery, instead of active recovery, is a form of rest that is recommended to be performed by athletes in between rigorous, intermittent exercise. With active recovery, time to exhaustion is much shorter because the muscles are deoxygenated at a much quicker rate than with passive recovery. Thus, if avoiding overtraining means preventing exhaustion, passive recovery or "static rest" is safest. If active recovery is performed during intense exercise, an athlete may find themselves in a state of being overtrained. The gradual variation of intensity and volume of training is also an effective way to prevent overtraining.
