Handstand is one of the ways for young people to keep fit. Why did you blush when you first started practicing handstand? The following content will answer this question for you, and you can refer to it.

When I first started to practice handstand, I felt my head was heavy and my face was swollen. I looked up in the mirror with anger and my face was red. But look at the trained gymnasts. They made such a long head and circled, but they were still "faceless" after landing. Why? Is your blood pressure high?

Don't! This has nothing to do with blood pressure. Blood is a kind of liquid in human body. In gymnastics, the human body turns and the distribution of blood often changes because of the gravity of the earth. When doing handstand, due to gravity, blood flows to the head and blushes. After long-term training, the regulating function of blood vessels has been improved. Before the handstand, the cerebral cortex began to adjust the slight contraction of the arterioles in the head in advance to prevent excessive blood from flowing into the blood vessels in the head. The establishment of this new conditioned reflex is the reason why those who have been trained many times "don't change their faces" when making posture changes.

Someone has done an experiment to make gymnasts, swimmers and track and field athletes do handstands and then measure the temperature near their ears. The results show that gymnasts are lower than swimmers and track and field athletes, indicating that gymnasts have less hyperemia of auricle blood vessels.

Some gymnasts who train intermittently may feel this way when they resume training. Just a few waves, or a few wheels, I feel my feet swollen and numb. At this time, if they make a jump, they will feel their feet hurt. This is also because after interval training, the conditioned reflex of vasodilation established in training disappears again, and centrifugal force throws blood to the far end of the body, which makes the blood vessels of the foot expand. It doesn't matter. After persistent training, the conditioned reflex of vasodilation recovered, and the blood of cardiovascular system was redistributed reasonably, which disappeared.
