The importance of exercise becomes greater the older we are, say researchers from Orebro University in Sweden, who assessed the health and lifestyles of 120 women who were at least 65 years of age.
While everyone knows that a sedentary life can lead to diabetes and heart disease, nobody was really sure just how much exercise is needed to reduce the risk, especially among older people.
In fact, surprisingly little exercise is needed, just as long as it’s every day and involves some exertion, the researchers discovered. “We are not talking about a slow pace, but at least one brisk walk or some physical activity requiring some exertion,” said Andreas Nilsson, one of the researchers.
The bottom line is not how long we sit around, but how much time we spend exercising. And, although they looked only at older women, the researchers reckon their findings would apply to men, and other age groups, as well.
