Can a person exercise effectively lose weight? This study will tell you the importance of joining the diet management. Dr. Hans-Peter Kubis, who led the research, and his research team published their research results in the journal Applied Physiology, Nutrition and Metabolism in 20 17. They found that women who don't control their eating habits and train three times a week will not lose weight because of exercise. The study of "Single Blind Exercise Test for Women with Different Body Mass Index" adopts two experimental methods. In the first experiment, 34 overweight, obese and normal women, aged 65,438+08-32, were trained in circular exercise three times a week for four weeks. Each exercise lasts for 45-90 minutes, and the intensity is controlled at 50-90% of the maximum oxygen uptake. The second experiment also found 60 women.
At the beginning and end of these two experiments, the weight, muscle and fat of all subjects will be measured, and blood samples of the subjects will be collected so that the experimental team can measure the level of appetite hormones. Here, bread contains insulin, leptin, islet amyloid polypeptide and auxin, so as to understand its potential contribution to the individual's weight response to exercise training, because these hormones will affect the body's hunger and food intake.
The purpose of this study is to determine whether exercise alone can make women lose weight, but the researchers did not tell the subjects the main purpose of this study. They were told to study the influence between exercise and cardiopulmonary health. Dr. Hans-Peter Kubis pointed out that this intention is to avoid the potential bias of the subjects and the deviation of the research data; In addition, he explained that when people know the relationship between exercise and diet, they will consciously control the quantity and calories they eat, which will obscure the focus of this study.
Finally, at the end of the four-week and eight-week exercise training programs, the researchers found that the exercise training in the two studies did not lead to a significant decline in the weight/body mass index (BMI) of the subjects; However, lean subjects increased their muscle mass and their appetite hormone levels were significant (P
When people know the relationship between exercise and diet, they will consciously control the amount and calories they eat, which hides the focus of this study. The researchers also found that overweight or obese women experience changes in appetite hormones, which partly explains why exercise alone can't make them lose weight. Dr Hans-Peter Kubis said that our body's regulation system is so precise that we can always find ways to make up for the energy loss after exercise. Whether you realize it or not, people who do a lot of exercise or training usually have a big appetite and consume more calories after exercise, which makes it impossible for you to achieve your goals smoothly.
Exercise is not only a weight loss research team, but also a special emphasis. This study is not to say that exercise is not good for your health, but that it is not enough to lose weight only by exercise training. So if you want to lose weight through effective exercise, you must integrate diet and lifestyle into the plan. Dr Hans-Peter Kubis said that when we only care about the numbers on the weighing machine and don't observe the ratio of muscle mass to fat mass, the progress of sports training will be forgotten. Therefore, we should know that through exercise training, we can increase our muscle mass and improve the changes between our bodies. If you only care about the numbers on the weighing machine, it will make you exercise.
