Scientists told how fitness and excess weight affect the heart.

Termination of fitness or fat accumulation with age - each of these factors can have a rather bad effect on the heart, but avoiding any of them, studies have shown, can protect your motor.

U.S. researchers found that of the more than 3,100 healthy adults they studied, those who improved or simply maintained their fitness levels were less likely to develop high blood pressure, high cholesterol, or other established risk factors for heart disease.

In addition, people who maintained their normal weight were outside the risk factor than people who became heavier over time. This may seem logical, but part of the new that appeared in the conclusions of the researchers is a change in the very concepts of "slimness" and "fat" as such. In general, people who maintained their physical shape over time seemed to counteract the negative effects of weight. And failures in fitness classes were not so bad if a person lost some excess fat in the body by itself.

"The findings suggest that protecting heart health is not as complex as some people think," said lead researcher Duck Chul Lee of the University of South Carolina at Columbia. That is, simply maintaining your weight and shape at your age may be enough for the benefit of the body. "If you are overweight, then weight loss and improving your fitness may be the best combination," Lee told Reuters Health. "But it is very difficult… ". "For many people," keeping fit "may be more achievable," Lee said.

The study, published in the journal of the American College of Cardiology, included 3,148 men and women from Dallas who were 40 years old on average. For six years, they have increased blood pressure at a rate of four percent each year, also high cholesterol at a rate of three percent per year, and the so-called metabolic syndrome at a rate of two percent per year. (Metabolic syndrome refers to a collection of risk factors for heart disease, including high blood pressure, unhealthy cholesterol, abdominal obesity, and high blood sugar).

But people who constantly engaged or improved their physical fitness — along the treadmill during trials — had fewer chances of developing these risk factors for heart disease. Their risk of high blood pressure or high cholesterol was 26 to 30 percent lower compared to people whose fitness levels decreased. And their risk of developing metabolic syndrome is 42-52 percent lower.

Similarly, when people increased their body fat percentage over time, they were more likely to develop heart disease. For each of them, a percentage increase in body fat "gave chances" to get at risk — from three to eight percent. But, in general, people who have gained weight remain healthy if they constantly maintain their level of fitness. And if overweight people “shed some fat,” they are confronted with some of the many negative consequences of refusing fitness. In the end, according to Lee, “the fact is that people who are active must remain active.” "Even if you do not see the benefits on the scales, you must stay in shape." "If you already do this, keep it up, and maybe increase the intensity if you can," Lee said.

“If you have a sedentary but healthy lifestyle,” he said, “then you can safely take on moderate exercises, such as brisk walking.” Lee also added, "however, people who are obese or have a chronic illness should consult their doctors first." "These people with a sedentary lifestyle will benefit most from such exercise in a short time," Lee said. He, however, referred in favor of full-fledged fitness classes. "Overweight people often do not notice a decrease in their weight when they first start classes - perhaps because they become more hungry and begin to eat more ..." "Do not be upset about this!" “said Lee.

“You can strengthen your cardiovascular system, even without extracting excess fat from your body. One way to say your shape is improving,” Lee said, “is simply to notice that you feel better when you do your usual exercises; if it’s easier for you, then you’ll become slimmer! " And to really lose weight, diets are also essential. “Most people lose weight through exercise,” Lee said, “if they also pay attention to calories, then they win twice!”
