It is an exercise method for developing trunk muscle strength and extensibility. It is a cyclical movement. Exercising the abdominal muscles is a feasible auxiliary method for treating gynecological diseases. First of all, sit-ups can exercise the abdominal muscles, tighten the abdominal muscles, and better protect the internal organs in the abdominal cavity. It should be noted that when doing sit-ups, the knee joint can be divided into two postures: extension and flexion, and the main functional muscles used to complete the movements are different. Doing sit-ups with the knees straight mainly exercises the iliopsoas muscle, which contracts the iliopsoas muscle including the rectus femoris under remote fixed conditions, causing the trunk to bend at the hip joint. Bend the knees and also produce hip flexion when doing sit-ups, which mainly involves the contraction of the rectus abdominis, including the internal and external oblique muscles, under fixed conditions, to form forward flexion of the trunk and anterior tilt of the pelvis. Obviously, the flexion of the hip joint causes the iliopsoas muscle to contract before the rectus abdominis muscle when lying on your back in the preparatory position, resulting in "active power deficiency" of the iliopsoas muscle during the sit-up movement. This is conducive to the rectus abdominis muscle to contract with all its strength under the condition of lower fixation, and to complete the movement "independently", thereby improving the training effect of the abdominal muscles. Therefore, if you want to get better abdominal muscle training results, it is recommended to do sit-ups with bent knees. At the same time, you should do sit-ups with reasonable breathing. When doing sit-ups, you should exhale when bending forward and inhale when lying on your back. However, if you mechanically complete the entire inhalation process while lying on your back, it will be detrimental to the completion of the movement. Therefore, in order to improve the quality of the movement, you must also pay attention to the technique, that is, start inhaling in the process of lying on your back, hold your breath and tighten your abdomen at the moment your shoulders and back touch the pad, and gradually lift your upper body. When the upper body is lifted to the point where you feel a bloating in the abdomen, exhale quickly, pull your body forward and lower your head to complete the movement. Sit-ups can also work your groin. There are many capillaries and acupoints in the groin. Doing sit-ups can stimulate the blood vessels in the groin through exercise, promote blood circulation in the abdomen, and thus treat and relieve gynecological diseases. At the same time, sit-ups can stretch the back muscles, ligaments and spine, and can regulate the central nervous system by stretching the spine. Moderate exercise can also improve the body's immune function, thereby enhancing the body's disease resistance. |
