Why do we get sore after a workout, and why do we get soreness after a workout?

After a large amount of activity, or after a long interval of not exercising, muscle soreness often occurs after the first exercise starts. This type of muscle soreness is not an immediate muscle soreness that occurs a few hours to about 24 hours after exercise, but usually lasts for about one to three days. Late-onset muscle soreness can be caused by muscle injury, muscle spasms, or connective tissue abnormalities, but connective tissue abnormalities are generally considered to be the biggest cause of late-onset muscle soreness.

The general public's belief that muscle soreness is caused by lactic acid buildup is incorrect. Muscles that are rarely used or trained, sudden, intense or excessively repetitive activities tend to cause delayed onset of muscle soreness, and the best way to prevent it is to do it in a gradual manner so that the muscles can load the heavy or repeated movements that will be performed. If there is muscle soreness, it should be treated with rest and hyperthermia, and it is not advisable to overdo it, otherwise it is easy to cause more serious injuries.

This is normal, everyone will have this situation when they are active, and then you insist on running every morning, don't do any big exercise after such a big exercise, too much exercise will damage the muscles. Just like we have a limit for running, when you reach a person's limit, your stomach will hurt a little, and then you have to run slowly, otherwise you will still hurt when you run to the limit in the future.

Simple. Excessive lactate secretion.

When you're done, don't stop right away, take your time and do a little more relaxation activity, which should be a little better, you can try it.

People who have just started exercising will encounter a problem, that is, they are sore the next day after exercising, what is going on? Many people who don't understand will be very scared and think that there is something wrong.

First of all, we need to rule out whether we have muscle soreness after exercise or tingling in our joints or muscles. Because people who have just started exercising can't really tell the difference between this situation, that is, they all feel that it is a pain all over their body, and if it is just muscle soreness, it doesn't matter. But people who have just started exercising may have a misunderstanding, that is, exercising is to practice if you want to practice, which is a very simple thing, although you don't want to discourage your enthusiasm, but you must know that exercising is a sport with a low threshold but a high ceiling.

Even if you say I don't need to go to that level, at least we still need to learn a little bit about the way of exercising, so that we don't get hurt, after all, we exercise to get healthy and in good shape, and it will be worth the loss to get hurt.

So let's get down to business, the substance that makes us sore after training our muscles is lactic acid. In addition, it is the muscle damage caused by your training (don't be afraid, the muscles will only get stronger and stronger when the injury is recovered).

So why do we produce lactic acid? When we do strength training, which is ironing, our bodies use the glycolytic system, which allows our bodies to cope with medium-to-high intensity exercise, but it lasts about two minutes. So why does it only last two minutes?

Because there is something that prevents muscle contractions during exercise, and that is lactic acid. During our strength training, the body uses the glycolysis system, which is mainly used for energy by sugar, and lactic acid is constantly being produced in this process, making you feel that it is becoming more and more difficult for your muscles to contract, and your muscles are very sore and pumpy. Knowing that the accumulation is to a certain extent that you can't complete a contraction, the whole process is about 2 minutes.

Our system needs to rest for 30-90s to recover in such a process, which is why we should control the rest between groups at 30-90s, because if the rest time is too short, it will not recover, we can not better complete the next group, and if the rest time is too long, the effect of exercise will not be very good.

The first point is that if you exert too much force, you will feel sore, on the second day, you will exercise for too long, so it will also be sore, and the third point is that you exercise in the wrong way, and there is soreness at this time.

The main reason is that after aerobic or anaerobic exercise, our muscles will produce lactic acid, so there will be soreness.

Because a large number of lactic acid bacteria are produced after strenuous exercise, these lactic acid bacteria will accumulate around the muscles and are difficult to dissipate, and they need to be relieved by stretching.

The production of lactic acid is a product of anaerobic metabolism and is determined by the intensity of exercise, and not all exercise produces lactic acid.
