Can thin people run
Outdoor - it's most beautiful outside!
Fat people and sport: being overweight does not rule out fitness.
What does a trained runner look like? Slim, lanky, wiry - most would say. But is that really true? In the forest I meet many runners who do not correspond to this cliché at all. There are also people sprinting through the area who carry a lot of weight with them. It has happened quite a few times that such a person has easily overtaken me. For me this is an indication that being overweight apparently has little influence on physical fitness.
So what does «fit» look like? Some doctors say that people with a body mass index over 25 will experience health problems sooner or later because of their excess weight, no matter how often they do endurance sports. Others say that even heavy people who exercise regularly can have a healthy cardiovascular system and may even live longer than unsporting, lean people. I recently came across a report in the American edition of Runner’s World magazine. They wanted to know from two experts:
Can you be overweight and still be physically fit?
"Yes", says Glenn Gaesser, Ph.D., director of the Healthy Lifestyles Research Center at Arizona State University.
"No", says Amy Weinstein, M.D., M.P.H., Assistant Professor. She runs a health clinic and studies the influence of obesity and exercise on diseases at Harvard Medical School.
Here is an excerpt from the interview:
Overweight and healthy - is both possible?
YES: Almost all health problems caused by being overweight can be alleviated or completely eliminated with moderate training. Those who exercise regularly improve their fitness automatically. About 30 minutes of brisk walking five days a week. Or 20 to 30 minutes of running three days a week.
NO: My research shows that exercise does not completely eliminate diseases caused by obesity, such as diabetes or cardiovascular ailments. We don't yet know why this is so. Certain hormones and proteins may be responsible.
Can an obese person outrun a slim person?
YES: This is possible if the heavier runner has the better qualifications: a larger lung volume, a higher lactate threshold and a better running style. Genes play a crucial role, as does running experience.
No: An overweight person would be faster if they weighed less. Theoretically, every kilo of body weight saved corresponds to one meter more per minute of walking. If a runner manages 5 kilometers in 20 minutes, he would be five seconds faster if he were a kilo lighter.
Is it better to exercise or lose weight?
YES: Exercise can reduce the risk of cardiovascular disease. The weight does not matter. Regular exercise has a positive effect on cholesterol levels, blood pressure, etc., even if you are not losing weight.
No: Losing weight is more advisable. There are over 50 medical diseases caused by being overweight - from diabetes and arthritis to reflux and certain cancers. Anyone who has already lost three or five kilograms improves their health more than through exercise. Both are best: lose weight and exercise.
