Another very good reason to exercise - live longer
"Exercise capacity is as good — if not better — a predictor of cardiac
mortality as the exercise stress test in asymptomatic women, researchers announced here at the American College of Cardiology (ACC) 53rd annual scientific session. " "Each unit increase on the DTS was associated with a 9% decrease in all-cause mortality and a 13% decrease in cardiac mortality. For each unit increase in exercise capacity, there was a 17% reduction in all-cause mortality and a 22% reduction in cardiac mortality." Note - DTS is the Duke Treadmill Score. What is exercise capacity? " Exercise capacity was determined by asking subjects what types of activities they engaged in, such as golfing, walking, gardening, running, squash, and jumping rope. Scores were assigned depending on the level of exertion required — golfing with a cart and walking at 2 mph received low scores compared with jumping rope or running at 5 mph, which received high scores. " So what to do? "Both Dr. Limacher and Dr. Gulati drew attention to how the findings strongly support the federal agency and society recommendations of moderately intense physical activity for at least 30 minutes every day. "We conclude that it is reasonable to achieve the highest level of physical fitness possible," Dr. Gulati said." http://www.medscape.com/viewarticle/471289 |
