PERSONAL HEALTHEven More Reasons to Get a Move Ony JANE E. BRODYPublished: March 1, 2010http://www.nytimes.com/2010/03/02/health/02brod.html?em“I’m 86 and have walked every day of my life. The public needs to wake up and move.”

These are two of many comments from readers of my Jan. 12 column on the secrets of successful aging. At the risk of sounding like a broken record, a new series of studies prompts me to again review the myriad benefits to body, mind and longevity of regularphysical activity for people of all ages.
Regular exercise is the only well-established fountain of youth, and it’s free. What, I’d like to know, will persuade the majority of Americans who remain sedentary to get off their duffs and give their bodies the workout they deserve? My hope is that every new testimonial to the value of exercise will win a few more converts until everyone is doing it.
In a commentary on the new studies, published Jan. 25 in The Archives of Internal Medicine, two geriatricians, Dr. Marco Pahor of the University of Florida and Dr. Jeff Williamson of Winston-Salem, N.C., pointed to “the power of higher levels of physical activity to aid in the prevention of late-life disability owing to either cognitive impairment or physical impairment, separately or together.”
“Physical inactivity,” they wrote, “is one of the strongest predictors of unsuccessful aging for older adults and is perhaps the root cause of many unnecessary and premature admissions to long-term care.”
They noted that it had long been “well established that higher quantities of physical activity have beneficial effects on numerous age-related conditions such as osteoarthritis, falls and hip fracture, cardiovascular disease, respiratory diseases, cancer, diabetesmellitus, osteoporosis, low -

In a review last year of 52 studies of exercise and colon cancer, researchers at Washington University School of Medicine in St. Louis concluded that people who were most active were 21 percent less likely to develop the disease than those who were least active, possibly because activity helps to move waste more quickly through the bowel.

Though early studies were conducted only among men, in a 2002 study published in The New England Journal of Medicine, Dr. JoAnn E. Manson and colleagues found that among 73,743 initially healthy women ages 50 to 79, walking briskly for 30 minutes a day five days a week, as well as more vigorous exercise, substantially reduced the risk of heart attacks and other cardiovascular events.

In another study, women who walked at least one hour a day were 40 percent less likely to suffer a stroke than women who walked less than an hour a week.

A 16-year study of 68,907 initially healthy female nurses found that those who were sedentary had twice the risk of developing diabetes, and those who were both sedentary and obese had 16 times the risk when compared with normal-weight women who were active.
