Why does stretching hurt more after exercise?

There is a high chance that you will overstretch, which can lead to pain or even muscle tearing. However, it's not so much that stretching itself hurts you, it's just that you're overstretched. Our muscles contain a special type of receptor cell called myospindle.

When you stretch, these cells send signals to neurons in your muscles, telling the central nervous system that you're overstretching. Eventually, the muscles contract and tighten to resist the pull. Such a reaction can cause pain, which is why people feel pain when they try to stretch at first.

It is also the reason why people have pain when they try to touch their toes. This pain, which is caused by the cascade of nerves, is rapid and intense.

Because the muscles are more tense after exercise, so there will be a tearing feeling when stretching, we must exercise properly to avoid overwork, after exercise, you can apply local hot compresses, local massage, and when necessary, you can take some drugs that promote blood circulation and eliminate blood stasis, such as blood capsules. Yunnan Baiyao capsules and so on**, this symptom can be relieved immediately.

When you are exercising, especially when exercising for a long time or strenuous exercise, the body's oxygen consumption increases dramatically, and due to the insufficient supply of muscle cells, the cells undergo anaerobic respiration to produce lactic acid, and you will feel sore! At this time, there is often a tearing sensation when stretching.

Lactic acid is produced during strenuous exercise, which can cause muscles to feel sour and weak, and can also cause damage to cells, but this damage is often short-lived and relieved by faster blood flow and a little rest. If, as is commonly referred to as lactic acid, there is no scientific explanation for the pain caused by the last exercise and no longer the pain caused by the next exercise, because both exercises produce the same amount of lactic acid.

Increasing the amount of exercise too quickly will cause the calf muscles to be in a state of tension for a long time, and the muscles will continue to pull, causing the tibiotic and fibular periosteal tear and injury of the calf, and the periosteum and periosteal blood vessels will dilate, congestion, edema or hemorrhage, and periosteal hyperplasia, this calf pain is called tibiofibular fatigue periosteitis. In severe cases, there is localized swelling on the inner calf or above the ankle joint, a burning sensation, weak back pedal movement, and severe pain, making it difficult to walk.

The main reasons for this phenomenon are: the ankle joint is too weak; The physiological load is too large; The pavement is too hard; The number of exercise intervals is too dense; The years of exercise are not long. It is recommended that you prepare for the activity from slow to fast and from light to heavy, and warm up more fully.

It is believed that this is caused by damage to muscle cells caused by the large amount of lactic acid produced during exercise. The point I give is: connective tissue strain.

We know that the endpoints of muscles are generally connected to bones through connective tissue, which in turn is connected to other tissues.

There are many causes of calf pain, in addition to stretching, the field is too hard, the landing action is incorrect and the lack of cushioning, etc., can cause the calf to be subjected to greater reaction force, resulting in calf pain. If none of the above reasons are true, it is probably because the amount of running is increasing too quickly.

It is absolutely not wrong to pay attention to stretching after the workout, which is conducive to the recovery of tired muscles as soon as possible, and is also conducive to maintaining good muscle flexibility and avoiding sports injuries. You provide less information to tell if the stretching is wrong or overstretched, if you can't be sure, it's best to stretch with the help and guidance of a coach.

Because stretching resets the joints and muscles of the body, reducing the risk of injury. Stretching before exercise to avoid injury, stretching after exercise is conducive to preventing muscle stiffness and relieving muscle soreness caused by exercise intensity; In other words, if you miss this 10-minute stretching phase after your workout, your risk of muscle soreness and injury during your next workout is greatly increased.

Exercise is not only a way to keep your body healthy, but also a way to make your body more perfect. We often see all kinds of perfect men and women in the gym stretching after exercise, what is the point of stretching? Why do I need to stretch after exercise?

01 Promotes blood circulation.

After strength training, the muscles become engorged, and stretching after the workout will get the blood circulating.

02 Drain lactic acid.

After strenuous exercise, the muscles produce a large amount of lactic acid, which accumulates on the muscles. Causes muscle soreness, which is extremely common in some people who are new to fitness or who have not been working out for a long time. Stretching at this time can effectively speed up the body's excretion of lactic acid and prevent muscle pain later.

03 Reduces muscle adhesions.

Muscles are adhesive, and timely stretching after exercise can prevent this situation, so that your own muscles will not become large muscles, so that the muscle lines look better.

04 Stretching after exercise is very necessary, and all fitness people must pay attention to it.
