According to a new report, exercise can be as effective as many frequently prescribed drugs in treating some of the leading causes of death. This is a major finding! From the Dec.11, 2013 NY Times:
Exercise as Potent Medicine
For the study, which was published in October in BMJ, researchers compared how well various drugs and exercise succeed in reducing deaths among people who have been diagnosed with several common and serious conditions, including heart disease and diabetes.
They ended up with data covering 305 past experiments that, collectively, involved almost 340,000 participants, which is an impressive total. But most of the volunteers had received drugs. Only 57 of the experiments, involving 14,716 volunteers, had examined the impact of exercise as a treatment.The researchers compared mortality risks for people following any of the treatment options.
The results consistently showed that drugs and exercise produced almost exactly the same results. People with heart disease, for instance, who exercised but did not use commonly prescribed medications, including statins, angiotensin-converting-enzyme inhibitors or antiplatelet drugs, had the same risk of dying from — or surviving — heart disease as patients taking those drugs. Similarly, people with diabetes who exercised had the same relative risk of dying from the condition as those taking the most commonly prescribed drugs.
On the other hand, people who once had suffered a stroke had significantly less risk of dying from that condition if they exercised than if they used medications — although the study authors note that stroke patients who can exercise may have been unusually healthy to start with.
Only in chronic heart failure were drugs noticeably more effective than exercise. Diuretics staved off mortality better than did exercise.
Over all, Dr. Ioannidis said, “our results suggest that exercise can be quite potent” in treating heart disease and the other conditions, equaling the lifesaving benefits available from most of the commonly prescribed drugs, including statins.
