Soreness is a normal phenomenon, and the main reasons are as follows:

1. During strenuous exercise, muscle glycogen decomposition is accelerated, and oxygen consumption is increased, so that muscle is temporarily in a relatively anoxic state. At this time, muscle glycogen can be converted into lactic acid through pyruvate and accumulated in muscle.

2. During anaerobic exercise, grape glycolysis produces a large number of intermediate metabolites such as lactic acid, which cannot be excreted through respiration, forming lactic acid accumulation. Too much lactic acid can make muscles feel sore, but it can be completely removed from the body within one or two hours after stopping exercise.

3. Delayed muscle soreness is caused by muscle fiber injury, which generally reaches its peak 24~72 hours after exercise.

4. A strong ache may mean that some actions are wrong, or that you exercise too much. It may also be that the training level of a certain aspect has dropped, or there are more centrifugal contractions of muscles.

Therefore, maintaining exercise can slow down the degree and frequency of muscle soreness. After strenuous exercise, muscles also need time to recover, so muscle soreness should be sporadic, not normal. Occasionally, muscle soreness can help us realize which part of the body lacks exercise, so as to strengthen the exercise in the corresponding part and reduce muscle soreness.

However, after muscle aches, you can appropriately reduce the amount of exercise to prevent the muscles from being really overworked.

Ways to recover from muscle soreness:

1, stretching and relaxing after fitness

Stretching after exercise can not only avoid the muscle mass that girls are most afraid of, but also relieve the sore parts through static stretching. Keep stretching for 2 minutes, then rest 1 minute, and repeat.

Step 2 supplement nutrition

Muscle soreness is often caused by muscle injury, so the most important thing is that nutrition must keep up. Adequate nutrition can make the body recover faster, produce excessive recovery and make muscles fuller and fuller.

Step 3 get enough sleep

During sleep, the body is mainly assimilated, and muscle repair is largely completed during sleep, so it is very important to get enough sleep every day. You must ensure at least 7 hours of high-quality sleep, and it is best not to stay up late after exercise.

4. supplement vitamin C.

Vitamin C participates in the biological oxidation process of muscle tissue, can promote substance metabolism, and plays an important role in improving the body's sports ability.
