Obese people involving in rigorous workout sessions may not have a prolonged lifespan, revealed a new study.
A recent study published in the International Journal of Epidemiology
was conducted by the researchers at Umeå University in Sweden. They analyzed data from 1.3 million Swedish men who were followed for 29 years from 1969 to 1996, and their aerobic fitness was measured by an electrically braked cycle test.
‘Fitter fatter individuals have lesser lifespan compared to that of unfit normal-weight individuals.’
They revealed that men in the highest fifth of aerobic fitness had a 48 percent lower risk of death from any cause, as compared to the lowest fifth of men.
Researchers reported that aerobic fitness was associated with reduced risk for death in normal and overweight men. However, the benefits of fitness were lower in obese men. Unfit normal-weight men had a 30 percent lower risk of death from any cause than obese men.
Peter Nordström, a researcher at Umea University, "Unfit normal-weight individuals had a 30-per-cent lower risk of death from any cause than did fit obese individuals. These results suggest low BMI (body mass index) early in life is more important than high physical fitness, with regard to reducing the risk of early death."
