Even moderate and regular exercise is good for older people because it decreases the risk of death among them, according to a new study. At least 15 minutes of physical five days a week would be a first target activity suitable for the elderly. “Exercise may include brisk walking, bicycling, swimming or gymnastics,” said David Hupin the department of clinical physiology and exercise at the Hospital of the University of St-Etienne-Lyon, France. “This message should be transmitted by general practitioners, who play a key and vital role in promoting exercise behavior in older people,” said Hupin. For the general population, an exercise program recommended 30 minutes at least five days a week (or 150 minutes per week) has been shown to reduce the average risk of death by 30 percent.
