What happens with our body during overtraining

Are you an passionate sports enthusiast? Do you train more and more in order to reach better results? Do you want to be better than the rest? Do you want to be the best? You actively move everyday and when you have a free day you feel culpable? If you have found yourself in this description, pay attention! It is very probable that heading towards “overtraining syndrome”.

If you think that getting into a condition of overtraining is nonsense, when you perceive people around you training harder than you, then you are wrong! On the contrary, it is more common than you might have thought. Recognising it in the starting stage is hard, because the symptoms are subtle and during physical activity even taken as normal. The risks resulting from overtraining are: tiredness, problems with sleep, pain in the muscles or repetitive cold and virosis. In addition you can also suffer from cardiac arrhythmia, joint pain, chronic inflammations or injury. When these problems appear it is usually a big mistake to continue with any sort of training or increasing the tempo. Passionate athlete may have a feeling that his/her performance is dropping (which in result is truth) and takes on even more burden.


The muscle works in two different ways, aerobic and anaerobic way. That means the muscle uses energy for contraction which is synthesized by splitting the sugars, if oxygen is present (aerobic glycolysis) or without oxygen (anaerobic glycolysis), which results in formation of lactic acid. After exhaustion of sugar sources, the energy is acquired from proteins. Fatty acids have indispensable role in the whole process of acquiring energy. Muscle tiredness caused by long-term work of muscles and how strong the repeated contraction is. It leads to decreased supplies of glycogen (composed sugar), lowered pH of the muscles, accumulation of lactic acid and consequent change in the blood supply of the tissue. All that is a signal of the muscles, that you need to rest, so the muscle wouldn’t be damaged and exhausted.

The situation only gets worse with further burdening, glycogen is substituted with proteins and insufficient oxidation (oxygen supply) leads to formation of more lactic acid. It is toxic for our muscle fibres, and with increased physical overload it can damage the fibres which may rupture. This exactly causes uncomfortable stabbing pain. Muscles needs for regeneration 24-48 hours for removing the toxic lactic acid and prevent damage.
