Four more studies prove that exercise leads to healthier aging
All four studies were published in the January 25 issue of Archives of Internal Medicine. The first study was based on data from the Nurses’ Health Study and found that women who were more physically active during middle age were more likely to be “successful survivors” by the time they reached 70. Walking and other moderate-intensity exercises lowered the risk for chronic disease, heart trouble, and cognitive impairment. The second study, which also focused on women, found that those who participated in a higher intensity exercise program four days a week had stronger bones and less chance of falling than women who were in a program that included relaxation, flexibility, endurance, and balance.
Another study done in Germany, found that moderate or high intensity exercise reduced the risk of cognitive impairment in men and women over the age of 55. A study done in British Columbia reported that women who performed resistance training 1-2 times a week had improved cognitive skills in the areas of attention and conflict resolution.
An additional commentary in the journal explained that almost all physical ailments later in life result partly from a lack of physical activity. James O. Hill, professor of pediatrics and director of the Center for Human Nutrition at the University of Colorado at Denver, commented, “I like to see this laid out, but every bit of information suggests that being active is the healthier way and being inactive is the abnormal, unhealthy way. Exercise is better than any drug or anything else we have for aging. There’s no downside. If this were a drug, it would be the safest, most effective drug in the universe.”
