Wang Yanwen's exercise and fitness are aimed at increasing or maintaining muscle mass, because muscle exercise can not only make the body beautiful, but also the two hormones secreted by muscles during exercise have great effects on increasing resistance and anti-aging. Naoko Ishii, a professor at the University of Tokyo, has been engaged in fitness since high school. He believes that he can survive from cancer and benefit from continuous muscle exercise since his youth. Dr. Muscle in the Japanese population, Professor Naoko Ishii, who teaches muscle to overcome cancer at the University of Tokyo, came into contact with fitness while studying at the University of Tokyo and was regarded as "Dr. Muscle" by the Japanese people. Professor Ishii, 64, suffered from malignant lymphedema three years ago and survived from cancer by relying on enough muscle mass to support his physical strength. (Editor's recommendation: Beware of cancer cells that will "run"! According to Professor Ishii, muscle is actually an important tissue of the human body to maintain body temperature and support the trunk, and it is not only used during exercise. Glutamate produced by muscle can increase lymphocytes, which are the source of human immunity; Professor Ishii thinks that he can overcome malignant lymphedema because he has been exercising muscles for many years, keeping his immunity at a high level. In addition, because the body has enough muscle combat resources, it has the physical strength to survive the harsh treatment courses such as radiotherapy and chemotherapy when treating cancer. Dr. Yuji Saikou, president of Saikou Hospital in Japan, who specializes in the diagnosis of human self-defense, also said: the staple food of lymphocytes and monocytes in immune cells is glutamate, and monocytes will develop into macrophages to devour bacteria and viruses after entering organs and tissues; In addition to dietary intake, exercise can also promote the production of glutamine in muscles, provide nutrition for the development of monocytes and improve immunity. (Editor's recommendation: Avoiding carcinogens is not enough! The key to help cancer cells metastasize is …) Exercise makes sugar stored in the form of muscle, preventing diabetes and dementia. After studying at Oxford University, Professor Ishii has been studying the effects of muscle exercise on human health from the medical and biological perspectives at the University of Tokyo. Professor Ishii said: Continuous physical exercise can increase muscles and exercise muscles can consume sugar, so muscle exercise can prevent diabetes. In Professor Ishii's research, 70-year-old people in Japan can still exercise their muscles smoothly. Muscle hormone secreted during muscle exercise is considered as an anti-aging hormone, which can increase nerve cells in the brain and is effective in preventing dementia. How can middle-aged and elderly people increase muscle strength under reasonable burden? How should middle-aged and elderly people exercise to increase their muscles and avoid being overtaxed? Professor Ishii said: Middle-aged and elderly people don't need to be opinionated about the number of squats, but should pay attention to the correct posture when squatting. As long as the posture is correct, squatting for four seconds and then standing for four seconds 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 the research of Shinshu University in Japan, it is relatively easy for middle-aged and elderly people to walk slowly for three minutes after a quick walk. For silver-haired people, as long as they walk for 30 minutes every day, they can strengthen their leg muscles and avoid the risk of falling.
