Researchers found that of the “least-fit” versus the “slightly more fit” in a recent study of nearly 4,400 healthy U.S. adults, roughly 20 percent with the lowest physical fitness levels doubled the risk of dying over the next nine years as the 20 percent with the next-lowest fitness levels. (In other words, those 20 percent who were nearly at the lowest fitness levels.) This is the familiar “bad news/good news” type of result. It is obviously bad news if you are a confirmed couch potato. However, it is genuinely good news for those who haven’t quite hit rock bottom in the sedentary lifestyle department but are not, by any stretch of the imagination, “exertive.” Apparently, those individuals who stay just moderately fit as they age may have greater longevity than those who are entirely out-of-shape, the study suggests.

Between 1986 and 2006, researchers assessed the fitness levels of 4,384 middle-aged and senior men and women during exercise treatmill tests. For approximately nine years thereafter, the researchers observed the study groups progress. The study considered such factors like obesity, high blood pressure and diabetes. This, in and of itself, highlights the importance of being physically fit. In an email to Reuters Health, lead researcher, Dr. Sandra Mandic of the University of Otago in Dunedin, New Zealand, stated: “Our findings suggest that a sedentary lifestyle, rather than differences in cardiovascular risk factors or age, may explain the two-fold higher mortality rates in the least-fit versus slightly more fit individuals.”

Nearly two-thirds of the least-fit study participants were not getting the minimum recommended amount of exercise, which is at least 30 minutes of moderate activity (like brisk walking) five or more days a week. “These results emphasize the importance of improving and maintaining high fitness levels by engaging in regular physical activity,” Mandic said, “particularly in poorly-fit individuals.”

After dividing the participants into five groups based on fitness levels, the researchers discovered that 13 percent of those who were in slightly better shape had died during the study period. However, 25 percent of the least-fit participants had died during the same period. Only 6 percent of the most-fit group (i.e., the ones who “hit the nail on the head,” so to speak) had died during the follow-up period.

The compelling finding was that overall, the five fitness-level groups showed little dissimilarity in their reported exercise routines over their adult lives, but where they contrasted was their activity levels in recent years. “Since it is recent physical activity that offers protection,” Mandic said, “it is important to maintain regular physical activity throughout life.”

And, naturally, imagine the health benefits we could all obtain if we sought to achieve the higher levels of fitness.

Any movement is a step towards better health and physical fitness. Walk a lap (or two) around your house or apartment. Put that TV remote away and get up to change the channels. As your body becomes accustomed to moving again, you will probably discover that you actually want to move more. Then you can slowly add additional movement to your daily routine. Increase the walk around your house to a walk around the block, a walk in the park, or even a walk through the shopping mall. Walking with a friend can often help to keep you on track(especially on those days when you’d rather sit and veg, then get your body moving). If you are physically able, take the stairs instead of using the elevator as often as you can. Park farther away from the entrance to the supermarket and make it a goal to put more and more parking spots between you and the entrance.

After a few weeks of regular physical activity, you will begin to feel the healthful benefits of movement. Then you’ll be ready for new ways to build flexibility, fitness, and muscle strength. Your chiropractor can advise you on how to become more physically active and help you to development an individualized program.
