In fact, the warm-up exercise refers to the preparatory activities performed before a certain exercise. For example, a warm-up before a basketball game; you need to warm up before you take a physical class. If you don't warm up enough before doing some aerobic exercise or strength training, you may be prone to sprains, discomfort or muscle strain during exercise.
Adequate warm-up exercises can have some effect on our exercise system. Make our heart beat faster, the temperature rises, the muscles reach a certain elasticity, and the speed of muscle reflexes and contractions reaches a certain level. This can effectively prevent our muscle strain and make the exercise process smoother.
First of all, we can personally feel the changes: increased body temperature, smoother joint movements, etc. Because warm-up exercises can increase the temperature of our telangiectasias, so that we can still supply enough oxygen to the body even during strenuous exercise.
Secondly, a proper amount of warm-up exercise can also make our joints secrete more lubricating fluid, which can effectively avoid injury. For example, the purpose of warm-up exercises such as shoulder or knee joints that we used to do before ironing is so that we can do various push-pulls next, the squat movement is smoother and smoother, and it is not easy for joints to pop.
Finally, warming up can also improve the flexibility of our tendons and prevent ligament strain.
The warm-up exercise meets the human body's need for oxygen by increasing body temperature, accelerating blood flow, and increasing the blood supply of the heart, which is conducive to obtaining sufficient oxygen supply during the activity. At the same time, warm-up exercises are also very important for our nervous system. With the right amount of exercise, the brain's response can be better improved. When the cerebral cortex is always in an excited state, it can improve the body's attention during exercise and can effectively prevent emergencies during exercise. In addition, through a moderate amount of warm-up exercises, you can also effectively alleviate the psychological tension and other issues before the game.
Conversely, if you don't warm up before you exercise, and you suddenly enter the state of exercise, your body will also show obvious resistance.
Because when the body is suddenly overburdened, it is easy for the nervous system to malfunction in the regulation of body organs. Such as the more common emergencies: sudden emergence of dizziness, dizziness, shock, abdominal pain, muscle strain and other conditions during exercise, sports shock may occur in severe cases.
In fact, this principle is similar to the situation where after a violent marathon race, you suddenly stop to rest, or sit down and rest, resulting in shock. Because after a long period of exercise, the human body suddenly stops the exercise, which will make it difficult for all parts of the body to accept it suddenly, and it is easy to produce dangerous phenomena.
Therefore, warming up before exercise is very useful and necessary. If you warm up well before exercise, you can avoid sudden problems during most sports.
