When doing aerobic exercise or anaerobic exercise, in order to improve the adaptability of various sports tissues and joints, friends often use warm-up and stretching. In the park, we often see some runners doing warm-up exercises before running, and after running, we will see runners doing muscle stretching activities. It can be seen that these two movements play an important role in the training process, so where are their differences?

1, the benefits of heart rate are different.

As we all know, when we are exercising, our heart rate will increase. If you don't exercise for a long time, your heart rate can't adapt to the intensity of exercise. If we lose exercise, it will put a burden on our heart, which will seriously cause shock. Our warm-up before exercise is to make our heart rate better adapt to the following amount of exercise. In the warm-up exercise, we will improve its adaptability and make its heart rate gradually accelerate. However, stretching after running is just the opposite of warming up. After a long period of training, our exercise intensity is very high and our heart rate is at the highest speed. If you do strenuous exercise again, you will be in a state of collapse and bring harm to your body. At this time, stretching is mainly to reduce the speed of heart rate, make it gentle, and let the muscles of the whole body rest.

2. Check whether your body is suitable for exercise and relieve fatigue after exercise.

We warm up before exercise to check our physical condition. If you have abdominal pain, cramps, heart discomfort and other symptoms, you can't do high-intensity training to protect your body. Stretching after exercise is to massage the tired body. People who stretch often feel this way. After stretching, muscle tension disappears, which is why it is playing a role.

3. Increase the range of muscle activity

Warm-up before exercise can better activate the physical strength of target muscles, enlarge the range of motion of joints and connective tissues, become more flexible, play their role in subsequent exercises, and reduce the risk of injury. The purpose of stretching after exercise is to relax the contracted muscles, strengthen their exercise, reduce muscle fatigue and stiffness, and facilitate the next activity.

Here are some warm-up and stretching exercises.

1. Taking 5 seconds to do in-situ jogging training can speed up your blood flow, make your breathing frequency and heart rate make better use of the following activities, and reduce the stickiness between joints.

2. Use 12 seconds to exercise the whole body joints, stimulate the excitement of muscles and enhance the flexibility of joints. Upper body exercise can't be missed.

There are many warm-up exercises. People who like sports can read some professional books and warm up in a targeted way. To sum up, stretching is also very important. We can affect the whole body by pulling one hair at a time, but we should be targeted. If you do leg exercises today, stretch your legs several times after the end.

In short, give a brief introduction and everyone will know the importance of these two actions. Just don't forget these two movements when exercising.
