Symptoms of muscle pain often appear in the process of fitness, which is very common in normal fitness activities. So is muscle soreness a sign of muscle growth? Next, let me introduce you. Let's have a look!

Generally speaking, there are two main reasons for muscle soreness.

The accumulation of metabolites such as lactic acid in the first training site.

This kind of pain is more common in moderate intensity, multiple times and multiple groups of strength training. This kind of pain can be felt immediately after fitness. Generally speaking, it will disappear after 2-3 hours of training, because it takes about 2.5 hours for our body to metabolize lactic acid.

The second kind of soreness does not appear until 24-48 hours after fitness.

What's your name? Delayed muscle soreness? , also called what? DOMS？ . I mentioned in my last article that the principle of fitness, especially strength/resistance training, is to break some muscles by resisting resistance, and then the body can achieve the goal of muscle growth by repairing and strengthening this broken muscle. So this kind of ache is because after that part of the muscle is torn, it decomposes a lot of protein, which makes the body mistakenly think that foreign substances are invading and produces inflammation to fight against this part of the substance. In short, it is the inflammation of the muscles in this area that causes the pain.

Generally speaking, the pain felt by friends after fitness is the first kind. Therefore, many people regard the soreness caused by metabolic wastes such as lactic acid as an effective sign of fitness, and the swelling feeling caused by temporary congestion of this part of muscles after training will give people a kind of? Practice today? Hallucinations.

But can we say that if the number of times is less, it will have no effect? In fact, many times, the training method with large weight and few times has an unparalleled effect on the growth of muscle strength, and the stimulation to the overall growth of muscle can not be underestimated.

For the second kind of soreness, this kind of soreness has a high correlation with the size of muscle stimulation, but it can not be completely considered as an effective sign of fitness. Because this kind of pain is more because your body was not used to such high-intensity training before, and now it is adapting.

So can you still exercise when your muscles are sore?

Muscle soreness can also be exercised, but the sore part must rest. For example, the chest muscles are already sore, so you can practice your back, legs, waist and abdomen, but it is not recommended to practice your shoulders the next day, because you need to use the triceps brachii to practice your shoulders, and chest muscle exercise also stimulates the triceps brachii to a great extent.

Whether it is sour or not, you must give your muscles enough recovery time after exercise (usually at least 48 hours rest), so as to have a better muscle gain effect. If you continue to exercise the sore part when you are sore, the risk of injury will increase greatly.
