Do you know why doing sit-ups hurts your stomach? Sit-ups are a very simple exercise that can effectively exercise the abdomen. Many people will do sit-ups, but some people will feel stomachache when doing this exercise. I collected and sorted out the information about why doing sit-ups hurts my stomach. Let's have a look.
Why do sit-ups have a stomachache? 1 Too many push-ups too fast. Muscle fatigue is in the waist muscles. Lactic acid bacteria are positive and intermediate substances produced in the whole process of glucose metabolism in the body during the whole process of fitness exercise. Because the relativity of fitness exercise is too much, which exceeds the compressive strength of strength training, lactic acid bacteria in the body cannot be further decomposed into water and carbon dioxide in a short time, and the lack of carbon dioxide supply produces anaerobic exercise metabolism, which in turn causes a large number of excessive substances of lactic acid bacteria to deposit in the body.
Therefore, pressing the abdomen after push-ups will make you feel sore, and it will be better after the lactic acid bacteria subside. Then do warm-up exercises before exercise, and stretching exercises after exercise can avoid or quickly repair muscle pain.
How to prevent stomach pain after push-ups?
/kloc-excessive exercise for more than 0/0 minutes can keep the endocrine system and respiratory tract in high quality, which is conducive to repaying the' oxygen debt' that cannot be repaid in fitness exercise. In addition, stress-releasing activities can relax muscles and prevent the whole metabolic process from being affected by partial circulatory system obstruction. Highly recommended stress release activities are: running, inspiratory gymnastics and flexion and extension training of various muscle groups. Flexion and extension training after exercise can eliminate muscle spasm, improve muscle blood circulation system, relieve muscle pain and stiffness, eliminate part of fatigue, and also have excellent effect on preventing knee joint injury.
Therefore, doing push-ups is inevitable and common. The most important thing is to keep a good attitude and take appropriate solutions. In addition, it is very important to warm up moderately before fitness exercise. Then try to do some relaxation exercises after exercise. Exercise in fun.
Why do sit-ups have a stomachache? The role of leg sit-ups
First of all, sit-ups can exercise abdominal muscles, tighten abdominal muscles and better protect organs in abdominal cavity.
It should be noted that when doing sit-ups, the knee joint can be divided into two postures: straight and bent, and their main functional muscles are different.
Straightening the knee joint to do sit-ups is mainly to exercise the iliopsoas muscle, but the iliopsoas muscle, including the rectus femoris muscle, contracts when it is far fixed, making the trunk bend at the hip joint.
Kneeling also produces hip flexion and sit-ups, mainly because rectus abdominis, including internal and external oblique muscles of the abdomen, contracts in a fixed state, forming trunk flexion and pelvis forward.
Obviously, the flexion and extension of hip joint makes iliopsoas muscle contract before rectus abdominis muscle when preparing for supine posture, which leads to "insufficient strength initiative" of iliopsoas muscle in the process of doing sit-ups, which is conducive to the full contraction of rectus abdominis muscle under fixed conditions and "independent" completion of actions, thus improving the exercise effect of abdominal muscles. Therefore, in order to get better abdominal muscle exercise effect, it is recommended to do knee-bending sit-ups.
The above is the introduction of the function of bent leg sit-ups. After understanding, we know that if we want to get better physical exercise, we should also choose methods according to the purpose of exercise. It is also worth noting that physical exercise also needs our long-term persistence to get better results.
