Stair test may predict your risk of dying of heart disease, cancer, study finds
If you can climb 4 flights of stairs in 55 seconds or less without stopping you have less risk of heart attack than those who can't. Seems easy enough.
For a glimpse into the state of your health and longevity, just head for some stairs.How people perform on an exercise test that requires them to move very briskly can predict their risk of premature death from heart disease, cancer and other causes, a study presented Thursday at a meeting of the European Society of Cardiology found.
Those with good exercise capacity — capable of high levels of physical exertion, say, on a treadmill — had less chance of dying early of any cause.
The participants in the study underwent an exercise echocardiogram, but there’s a much easier method to check your exercise capacity in a similar way: See if you can climb four flights of stairs at a fast pace — in under a minute — without having to stop, said Dr. Jesús Peteiro, the study author and a cardiologist at University Hospital A Coruña in A Coruña, Spain.
If you can do it, you have good functional capacity. If not, it’s a sign you need more exercise, he noted. Peteiro wasn’t surprised by his study’s findings.
“Physical activity has positive effect on blood pressure and lipids, reduces inflammation and improves the body`s immune response to tumors,” Peteiro told TODAY.
WHAT IS A METABOLIC EQUIVALENT?Their effort levels were measured in metabolic equivalents, or METs. One MET is equal to the energy it takes to sit quietly. Walking briskly requires about 3 METs, while jogging takes more than 6. This study defined good functional capacity as achieving a maximum workload of 10 METs.
Being able to climb four flights of stairs in about 45-55 seconds would be equivalent to 10 METs, Peteiro, estimated.
When the study participants were followed up over the next five years or so, each MET they achieved during the exercise test was associated with a 9 percent lower risk of cardiovascular death, a 9 percent lower risk of cancer death and 4 percent lower risk of other causes of death, the European Society of Cardiology noted.
In people with poor functional capacity, the death rate from heart disease was almost three times higher and cancer deaths were almost double compared to participants who had good exercise capacity.
