There is no denying that physical activity is an essential element of overall health and wellbeing. It may even reduce risk for cognitive decline during aging. But just because it is good for you, does it mean more is always better? On social media we see people pursuing spartan races, triathlons and other endurance races. Doctors see more and more people with ailments and injuries resulting from overtraining combined with underfueling.
In it of itself, training hard isn’t a problem. Training with inadequate rest and nutritional replenishment, however, is a recipe for illness and injury. Often patients who combine exercise with overzealous calorie restriction develop decreased production of T3 and increase production of reverse T3-often with normal TSH. This results in slowing metabolism.
Another consequence of overtraining and underfueling is depression of the immune system, as well as GI symptoms. So it seems that more isn’t always better. More can be okay when it’s accompanied by more food, more nutrients and more rest and recovery.
Have you experienced symptoms of overtraining? What were your symptoms?
Did you feel that it caused your metabolic rate to slow down making it hard to lose weight and easy to gain?
