"There is no such thing as overtraining. There is only undereating,
undersleeping, and failure of will."
-The Barbarian Brothers
Expecting a list of *all* possible symptoms is unrealistic: there might
be subtle physiological or psychological reactions to overtraining that
haven't even been identified yet or that are more likely indicators of
other problems. That being said, here are lists of symptoms from
several different sources:

* Unexplained underperformance
* Prolonged recovery
* Reduced maximal heart rate
* Reduced maximal blood lactate concentration
* Increased sleeping heart rate
* Excessive fatigue
* "Heavy" muscles
* Upper respiratory tract infections or other frequently recurring
infections, such as colds
* Increased susceptibility to illnesses and allergies
* Sleep disturbances
* Changes in appetite
* Depression
* Loss of competitive drive
* Increased anxiety and irritation
