Exercise decreases death from all causes
Exercise Decreases Death From All Causes
New study findings should give "couch potatoes" one more reason to get moving -- being in good physical shape appears to reduce middle-aged men's risk of dying not only from cardiovascular disease, but from cancer and other causes as well.
In fact, Finnish researchers report that poor cardio-respiratory fitness increases the risk of premature death as much as well-known risk factors such as smoking, high blood pressure, obesity and diabetes.
Physically unfit men, who had the lowest oxygen uptake, were almost three times more likely to die from any cause, even after the researchers accounted for factors that could have influenced the results, such as age, smoking and alcohol use. The risk of death was similar in men who could only complete a short exercise test.
Even though being physically fit is usually thought to help the heart most of all, the benefits of staying in shape appeared to be wide-ranging. Men with high oxygen uptake and long exercise tests were less likely to die not only from cardiovascular disease, but from all causes, including cancer, according to the study.
While the effects of exercise on cardiovascular health are well known, the link between good physical fitness and a reduced risk of death from other causes is not well understood, the report indicates.
