There are two kinds of muscle soreness, one is muscle soreness that occurs immediately during or after exercise, which is caused by lactic acid accumulation, because the lactic acid content reaches its peak at this time; The other is muscle soreness on the second or third day of exercise, mostly caused by muscle injury; It is not surprising that occasional muscle fiber injury leads to muscle soreness, because the process of muscle growth is the process of excessive recovery after muscle fibers are destroyed, but long-term or severe muscle soreness is the embodiment of overtraining, which will cause great harm to the body.

Solution to muscle soreness:

1. You can use a hot towel to hot compress these sore parts, which will be relieved in two or three days.

In addition, in order to avoid getting hurt again next time, you can usually take time (for example, before going to bed at night or getting up in the morning) to practice sit-ups and squats, so that it won't hurt to stand up in the next long jump.

Methods to prevent muscle soreness are:

1. Do muscle stretching before and after fitness, mainly static stretching.

2. We must follow the principle of gradual progress. No matter whether it is weight-bearing or training intensity, muscle soreness will still occur for beginners who don't have weight-bearing fitness, let alone weight-bearing. No matter how much weight you can lift, you should start from zero strength and add it slowly.

3. Supplement protein and carbohydrates for muscle repair after exercise.

4. Remember to massage and relax your thighs after exercise, and pat more.
