According to the report, a research paper on the weight and exercise of female athletes appeared in Science magazine. The author of this paper is James, a cardiovascular doctor from Massachusetts General Hospital. Gu Sai, He and his team found through research that the lighter the weight does not mean the higher the improvement of sports ability, especially for long-distance runners, which may change the cognition of athletes.
The lighter the better? How did the concept of "new concept" come into being?
Body mass index, as an important index, has been cited for a long time in previous human health research. The so-called body mass index, that is, body mass index, is an internationally accepted standard to measure the degree of obesity and health. You can calculate an individual's body mass index through a certain formula. Gusset found that many researches related to body mass index like to take athletes' cases as arguments, which led to the emergence of sports circles and the public. The lighter the better? The point of view.
At the same time, the pinch plate found? The lighter the better? This view is generally suitable for male athletes, especially endurance sports such as long-distance running. People who get the best results usually have a relatively low body mass index. However, there are few cases of female athletes as research arguments, which aroused Gu Sai's curiosity, so he and his colleagues planned to conduct a number of professional tests on athletes to study whether there is an exact relationship between weight and athletic ability.
What tests did Gusset pass to get the latest discovery?
Gusai and his colleagues invited 2,200 professional athletes and active exercisers to take the test, with 50% male and 50% female. In the test, volunteers were asked to run on a treadmill, and then the researchers dynamically tracked their oxygen intake. A number of follow-up results show that volunteers, whether professional athletes or active ordinary people, consume more oxygen with the acceleration of pace.
But when their pace is accelerated to a certain extent, the oxygen consumption has reached the upper limit and will not continue to rise. This is a person's maximum oxygen intake. Like the body mass index, the maximum oxygen uptake is also an index to measure personal health, which refers to the maximum amount of oxygen a person needs for aerobic exercise under the condition of sufficient oxygen supply. In previous studies, the greater the maximum oxygen uptake, the stronger the athletic ability.
What was the test result? What does this mean?
The test results obtained by Gusai and his colleagues are that men and women over 30 do better in aerobic exercise with low body mass index, but this situation is not obvious for athletes under 30. What surprised the researchers even more was that the data of 235 female athletes showed that the maximum oxygen uptake decreased regardless of whether their body mass index was the highest or the lowest.
This shows that there is no negative correlation between the body mass index value of male and female athletes and their athletic ability, that is, the lower the body mass index value, the better the athletic ability. In addition, athletes of different ages have different sports performances, so coaches can't take body mass index as the only goal when making training plans. Among the female athletes who took part in the smash test, there was one athlete, Mary? Kane broke five bones after taking the coach's advice to lose weight, which shortened his career by three years.
For many professional athletes, their career usually does not exceed 15 years, and losing three years means losing many opportunities for exercise and achievement. Therefore, before considering whether to lose weight, it is best to do it according to the actual situation of the individual. The author thinks that it is more important for athletes to maintain healthy eating habits and sleeping habits, and never lose weight at will.
