Physical fitness and no excess weight can reduce the risk of death, according to a study.
In a study of 14,345 adult men, mostly white and come from upper middle class, the researchers found that maintain or improve fitness was linked with lower risk of death.
Each unit of increase in fitness (as measured by the MET/metabolic equivalent of task) for six years, it has nothing to do with the reduced risk of death by 19 percent of heart disease and stroke-related deaths and 15 percent lower risk of death by other causes.
Being fit is less risk associated with high mortality, regardless of its condition BMI.
"This is good news for people who are physically active but can not seem to lose weight," said Duck-Chul Lee, leader of the study was quoted as saying by Medindia.
"You do not have to worry about your weight as long as you continue to treat or improve your fitness level."
According to the researchers, the results of the study highlight that physical inactivity is a risk factor for death from heart disease to stroke.
The researchers also found no association between change in percentage body fat or weight gain and risk of death.
The participants, average age 44 years, took part in the long run, and do aerobics in the large-scale longitudinal studies. they undergo at least two comprehensive medical testing.
The researchers used a maximal treadmill test to assess physical fitness (maximal MET), and height measurements seta weight to calculate BMI.
They note the change in BMI and physical fitness for six years. After more than 11 years to cultivate, the researchers determined the relative risk of death among men who had died, that maintain or increase fitness over a period of six years.
The study has been published in the circulation of the Journal of the American Heart Association.
