Wang Yanwen Sports and fitness are all aimed at increasing or maintaining muscle mass, because exercising muscles not only makes the body beautiful, but the two hormones secreted by the muscles when exercising are also helpful in increasing resistance, It has great effect in anti-aging. Professor Naokata Ishii of the University of Tokyo, who has been engaged in fitness training since high school, attributes his ability to survive cancer to his continuous muscle training since his youth. The "Dr. Muscle" in the eyes of the Japanese people uses muscles to overcome cancer. Professor Naokata Ishii, who teaches at the University of Tokyo, was exposed to fitness exercises when he was a student at the University of Tokyo. He is the "Dr. Muscle" in the eyes of the Japanese people. Professor Ishii, 64, suffered from malignant lymphoma three years ago. He relied on sufficient muscle mass to sustain his strength and survived the cancer. (Editor's recommendation: Be careful of cancer cells that can "run away"! Seemingly ordinary symptoms are actually alarm bells for lymphoma) According to Professor Ishii: Muscles are actually important tissues for the human body to maintain body temperature and support the trunk, not just during exercise. Will be used. Glutamic acid produced by muscles can increase lymphocytes, which are the source of human immunity. Professor Ishii believes that he was able to defeat malignant lymphoma because he has exercised muscles for many years and kept his immunity at a high level. In addition, because the body already has sufficient muscle preparation resources, it is only during cancer treatment that it has the physical strength to withstand harsh treatments such as radiotherapy and chemotherapy. Dr. Yu Horiguchi, director of Japan's Horiguchi Hospital and specializing in the diagnosis of human body self-defense, also said: The staple food of lymphocytes and monocytes in immune cells is glutamine. After monocytes enter organ tissues, they will develop into giant cells. Phagocytosis engulfs bacteria and viruses; in addition to glutamine being absorbed from the diet, exercise can also prompt muscles to produce glutamine to provide nutrients for the development of mononuclear spheres and improve immunity. (Editor's recommendation: Avoiding carcinogens is not enough! The key to helping cancer cells metastasize is actually...) Exercise to store sugar into muscles and prevent diabetes and dementia. After studying abroad at Oxford University, Professor Ishii has been studying medicine and From a biological perspective, we study the impact of muscle training on human health. Professor Ishii said: Continuous exercise to increase muscle can consume sugar through muscle activity, so exercising muscles can prevent diabetes. In Professor Ishii's research, there are elderly people in their seventies in Japan who are still successfully exercising their muscles. The muscle hormones secreted when exercising muscles are considered to be an anti-aging hormone, which can increase the number of nerve cells in the brain and improve the function of muscles. Effective in preventing dementia. How can middle-aged and elderly people increase muscle mass under reasonable burden? How should middle-aged and elderly people whose physical strength cannot compare with young people exercise to increase muscle mass while avoiding excessive burden on the body? Professor Ishii said: Middle-aged and elderly people do not need to stick to the number of times when doing squats, but they should pay attention to the correct posture when squatting. As long as the posture is correct, a deep squat that takes four seconds to squat down and another four seconds to stand up is more suitable for middle-aged and elderly people. This slow and relatively gentle squat can exercise muscles as long as it is done five times a day. In addition, according to research from Shinshu University in Japan, walking fast for three minutes and then walking slowly for three minutes is a relatively easy exercise method for middle-aged and elderly people. Walking for only 30 minutes a day can strengthen the muscles of the legs and avoid the risk of falls for the elderly. .
