Sit-ups are the most basic sport, and like push-ups, almost everyone has done it. There are still a lot of fitness people, and it is the best choice for exercising abdominal muscles. However, a health survey report recently released by the United States has been rumored on the Internet. The results show that it has always been regarded as the most effective sit-up exercise for exercising abdominal muscles. It is actually a dangerous exercise; it can also cause lumbar intervertebral discs. protruding A health checkup in the United States showed that 56% of soldiers suffered from back injury due to long-term sit-ups. In an editorial of the US Navy, the campaign was completely banned. The Canadian military has removed the sit-up project from the soldier training catalogue and used a sandbag that weighs 44 pounds (about 40 pounds) to exercise. A Canadian university professor said that many studies have shown that sit-ups can cause compression on the spine, and long-term exercise can compress nerves, causing pain, which can cause lumbar disc herniation. Sit-ups really endanger health? The answer to the expert is not the sit-up exercise itself, but the traditional sit-up action. Straight legs and hands clasping the head to lower the upper limbs are the traditional movements of sit-ups. Nowadays, many people do this when they do sit-ups. Experts pointed out that this action is wrong. If you do such an action for a long time, it will cause damage to the three parts of the human body. The first is cervical spine damage. Due to excessive force on the head, the neck is excessively flexed, which can easily cause neck muscle strain, especially for junior high school students and elementary school students whose body has not yet developed. Followed by spinal injuries. Sit-ups that are in place can involve the gluteal muscles and the abdominal muscles, which requires a bow back and can easily lead to damage to the spine. This risk is not only for people with poor abdominal muscle strength, but also for those who exercise regularly. They need to do enough sit-ups in their training tasks to make the abdominal muscles extremely tired, which may also cause spinal damage. The third is the pressure of the gluteal muscles. The main role of sit-ups is to increase the strength of the abdominal muscles, but many are eager to seek too much force, so that the contraction of the abdominal muscles into the contraction of the gluteal muscles, will form the pain of the gluteal muscles. What is the standard action for sit-ups? : Hands naturally stretched flat on the side of the body or hands crossed on the chest; if both hands are placed on the back of the neck or behind the head, be careful not to hold the back of the neck with both hands. She pointed out that such sit-ups are more difficult, but practitioners should not be greedy. At first, they can make achievements, not hard, and gradual. China's Hong Kong, Macao and Taiwan regions have changed the traditional posture of sit-ups in various schools, and understand the unscientific reason that "hands hold their heads". However, the major, middle and primary schools in China have not yet made adjustments. In this regard, the education authorities urgently need to introduce standards for sit-ups to protect the health of children.
