Zhang Weiting often goes to parks and primary schools to exercise after dinner every day, but he feels that his figure has not changed and he has no real feeling of exercise at all? Japanese health science professor said, in fact, as long as you change the speed of walking, you can greatly increase calorie consumption! Don't want to go to the gym, don't like ball games. When many people want to lose weight and improve their health, they will start with the easiest walk, but it is easy to give up because they can't see obvious results. Professor Kenichi Genji of the Health Science Research Department of the Institute of Matsumoto University in Japan pointed out that it would be a great pity if you just keep a monotonous pace in order to lose weight. The research of Ohio State University shows that switching between fast and slow pace can increase the calorie consumption by up to 20% compared with walking at the same speed, because changing the speed will bring load to the leg muscles and increase the calorie consumption. I used to hear the intermittent walking method of walking fast for 3 minutes, walking slowly for 3 minutes and alternating several times. Professor Yuan said that in fact, as long as the pace is changed to "4.4 walk" with four steps fast and four steps slow, it can be practiced easily in daily life. No matter when walking to the station or walking, you can practice easily. According to the experiment, one group of subjects walked for five minutes in a normal way, while the other group did "4.4 walking". It turns out that "4.4 walking" can increase the heat consumption by 20% compared with ordinary walking! In addition to losing weight, a simple walk on weekdays also helps to keep fit and prevent cancer. The National Cancer Center of Japan pointed out that people who actively participate in leisure sports are unlikely to get breast cancer. Obesity-prone women and postmenopausal middle-aged and elderly women can help prevent breast cancer even if they only do leisure exercise once a week. A study at the University of California, San Diego also pointed out that walking every day can prevent aging.
