Fatigued Athlete Myopathic Syndrome

A condition that can be regarded as an irreversible end-stage result of overtraining. Common to these athletes is a history of high volume endurance training and racing, a precipitous decline in performance unrelated to ordinary ageing, and an inability to tolerate and adapt to previously accustomed exercise training loads.
DiffDx Over-training. In contrast to FAMS, over-training is an acute consequence of doing too much too fast for too long at one time which, with rest and a gradual buildup of exercise, allows the athlete to return to the previous level of training a speed. FAMS athletes are worn out and can’t return to previous training loads; extensive rest periods do not alleviate the symptoms, as rest does with over-training.
