Overtraining is mainly because the training intensity is too high or the training time is too long ... For example, strength training leads to strain or tear of muscles, ligaments and joints, such as dizziness, nausea or fainting during cardiopulmonary training; The damage caused by the former may be insufficient warm-up, overweight, excessive arc of action or insufficient protection; The latter may be due to poor cardiopulmonary function, insufficient blood supply and other reasons; The harm of the former is obvious, and the latter may lead to circulatory diseases! Therefore, training must be gradual, especially for junior trainers. Training should be slow in the initial stage, advanced appropriately in the middle stage and excessive in the later stage. ...
Physical fatigue that is difficult to recover after training is also an excessive performance ... such as muscle aches, listlessness and general weakness! Fitness people must have experienced muscle soreness after training. Generally, they can recover in three or four days, but some trainers still have obvious soreness after a week, which is overtraining. If the training time is particularly long and you feel weak after training,
Being in a trance and feeling weak all over is also an excessive performance, such as common aerobic exercise and comprehensive exercise, such as running, playing ball games, climbing mountains and so on! Trainers must pay attention, because individual physical fitness and physique are different, training intensity should have its own standards, and don't blindly follow others' intensity training! And sleep and diet after training are the key to recovery, so you must eat well and sleep well! ! !
We must pay attention to overtraining. Complications and diseases caused by overtraining are not uncommon ... For example, some people catch a cold and have a fever after training, which may be due to inflammation and decreased immunity caused by training! Why does fitness cause inflammation? In fact, the body has always had inflammatory reaction, and the process of body metabolism itself is the process of oxidation reaction, but this oxidation process is reasonable and controllable, but excessive oxidation will lead to excessive inflammation, which will cause immune response, such as a series of symptoms such as colds and fever ... Of course, inflammation itself will also lead to decreased immunity!
I don't know if you have heard of rhabdomyolysis ... this is a typical injury caused by overtraining! Although the cause may also be malnutrition and lack of rest, the direct cause is inflammation caused by muscle injury caused by training, which is generally easy to happen to beginners and retrainees. The consequences of rhabdomyolysis are very serious, so we must pay attention to it and don't blindly worship and retrain!
