Why do you feel weak after a period of fitness? Protect yourself while exercising. Exercise is good for enhancing immunity. Aerobic exercise is very beneficial to our health. This exercise is something we often do. Let's see why we feel tired after a period of fitness.

Why do you feel weak after a period of fitness 1 The first reason: normal phenomenon.

The first reason is simple and comes from our normal phenomenon. Normal people generally feel weak after exercise.

On the contrary, it is strange that we still feel energetic after a fitness. If we still feel that we have a lot of strength after fitness, it may be that you haven't exercised enough. Try to add some weight and strength next time. Therefore, it is normal to feel general weakness after exercise, and it may be that one's strength is exhausted during exercise.

The second reason: excessive overdraft.

The second reason may be that we exercise too much during the exercise and our physical strength is overdrawn. In the process of exercise, choosing the wrong sports or choosing the strength beyond your ability will lead to excessive exercise. After exercise, our bodies will feel exhausted and have no strength at all.

If you have no strength after exercise, feel uncomfortable and don't want to exercise all your life, then you may have exercised too much, and you have overdrawn your physical strength and health. This has no fundamental impact on fitness, but it will affect our health. So please know yourself first, and then choose fitness programs and make plans for your fitness efforts.

The third reason: I didn't relax well.

The third reason is that we didn't relax after exercise. If you exercise for a long time, you are still tired and sore, probably because your body is not well relaxed. When we finish exercise, our bodies will definitely feel tight, and our muscles will feel uncomfortable because of the accumulation of lactic acid.

At this time, relax and stretch some muscles, such as stretching. Use stretching to help your body relax. When stretching, try to stretch every movement in place and let your body relax slowly.

The fourth reason: not enough rest

The fourth reason is that our bodies don't get enough rest after exercise. After the exercise, the first thing to do is to have a full rest, so that the body can be healed and restored, so that physical strength can be restored, so that the body can rest and return to its previous healthy state.

After exercise, we can relax ourselves by taking a hot bath and sleeping with high quality, so that our bodies can be repaired and rested. And pay attention to the frequency of fitness. When we are in fitness, if we do all-round training every time, it is best to train three times a week. If you do local training every time, practice your back today and your legs tomorrow, you can do it five times a week. This is the choice of experts, and novices still have to practice three times a week.

Why do you feel weak after a period of fitness? Why do you feel sore after exercise?

Soreness, that is, muscle soreness, does not only appear after exercise. Working at a desk for a long time, or sometimes doing housework will appear. If it is sports, especially in these cases.

With the increase of metabolism, the toxicity of metabolic waste to tissues increases.

Because one or two hours after stopping exercise, lactic acid will be completely removed from the body; However, after lactic acid accumulation, the local osmotic pressure increases, which will cause muscle edema and muscle soreness for a long time. Another important reason is muscle fiber and soft tissue injury.

Relax after exercise

Relaxation exercise is very important, especially stretching the corresponding muscle parts, which can promote circulation and help to slow down or even avoid muscle soreness.

Keep a posture for a long time. For example, if you stay in a posture for a long time while sleeping, your muscles will not be relieved. Not only will your muscles be paralyzed, but your neck will be sore, and the whole person will feel sore. Therefore, it is necessary to exercise and exercise your bones and muscles when appropriate, so as not to be sore all over.

Slight damage to muscle fibers and connective tissue will be manifested in the form of soreness. I didn't feel anything at the time. I began to feel sore in a day or so, which is medically called delayed muscle soreness. Generally, the pain will reach its maximum within 48 hours, and then it will gradually disappear. However, when you do these exercises again, you will find that muscle soreness is obviously improved, or it is completely gone. This is because muscles and connective tissues are exercised and stimulated.

It is generally believed that muscle soreness is related to energy metabolism inside muscles. If you take part in a football match, your muscles, especially those in your legs, will contract violently during the fast running. Muscle contraction requires energy, which is provided by the decomposition of muscle glycogen in muscle tissue. In the case of adequate oxygen supply, such as muscle rest, muscle glycogen can be directly decomposed into carbon dioxide and water through pyruvate, releasing energy.

However, there is no unified view on the causes of delayed muscle soreness. Some people think that muscle fibers tear a little after long-term exercise; Some people think that there is some damage to the connective tissue of muscle. The above two theories have not been confirmed by many experimental materials. Because of the muscle ache caused by this reason, we can do some stretching exercises to lengthen the muscles, or do some massage or acupuncture to relieve this muscle ache.
