When you grew up, your parents or teachers probably told you to sit and stand straight, instead of slouching your back and shoulders. They themselves may not have exactly known why that was important, it just seemed that way. But more recent science has found that they were actually right in many more ways than they imagined. As it turns out, good posture enhances physical fitness, helps reduce stress, and contributes to healthy aging.
That good posture plays a role in health and fitness should come as no surprise. Only when the body is properly aligned, the supporting ligaments, tendons and muscles can function at their best. Sitting or standing hunched over for hours – as many of us do at work and other activities – can lead to chronic pain and permanently debilitating damage. By contrast, good posture can help prevent such wear and tear and maintain greater flexibility and strength.
Research suggests that good posture can also foster people’s psychological well-being. One study from the University of Auckland, New Zealand, found that the way people conducted themselves physically did indeed influence their self-esteem and how they were able to cope with stress and problem solving. As tests showed, sitting or standing upright helped participants feel more powerful and competent when facing a number of challenging tasks they were assigned to. In other words, bodily experiences can significantly affect cognitive and emotional states as well, the researchers concluded.
The issue becomes ever more pressing with age. A study from Japan discovered connections between good posture and the risk of future disability. Participants who sat, stood and walked even only slightly bent forward in their mid-life years developed greater physical limitations than their counterparts who generally maintained an upright posture. The differences became ever more pronounced as they got older, and were eventually quite significant in terms of their overall health status.
There is also a social dimension to the way we present ourselves physically, especially in our later years. As surveys have shown, old age is commonly associated with physical deterioration and visa versa. Many seniors feel left behind and isolated from society, in part because of actual physical (and perhaps mental) shortcomings, but also based on false assumptions that they no longer can keep up. However, while some slowing down may be an inevitable part of nature, there is no need to accept premature degeneration and decline.
And there is much that can be done to counteract those processes. For example, stretching, yoga and other exercises that promote flexibility can do wonders for an aging body. So can brisk walking, keeping a good stride, moving with ease and confidence – all of which are signs of good health and vitality. A positive attitude and outlook on life can also do some good, particularly when it shows on the outside.

That regular exercise is important for good health is old news. From controlling weight and staying in shape, to fending off disease, to aging well, being physically active is a central component of wellbeing. As much as this message is considered to be self-evident, surprisingly, there has never been actual scientific proof that it is true.
For instance, while countless studies have suggested that exercise can be beneficial in many ways, including for slowing the aging process in older adults, it can only be said with certainty that most people who are healthy do in fact exercise – but not that their exercising makes them healthier. Now, a new study tried to show just that.
Unlike other research projects of its kind, this one specifically sought out participants who were not especially fit but adhered to a mostly sedentary lifestyle and even showed signs of age-related physical decline.
“For the first time, we have directly shown that exercise can effectively lessen or prevent the development of physical disability in a population of extremely vulnerable elderly people,” said Dr. Marco Pahor, the director of the Institute on Aging at the University of Florida in Gainesville and lead author of the study report, to the New York Times.
For the study, the researchers recruited 1,635 men and women between the ages of 70 and 89, who were mostly sedentary but still able to walk independently a distance of at least 400 meters (a quarter-mile). Then they split the participants up in two groups, assigning one to a regular exercise regimen, the other to a health education program that did not include exercising.
Over a period of about two and a half years, the exercising group showed 18 percent fewer incidences of temporary physical disability and 28 percent reduced likelihood of long-term to permanent disability compared to their non-exercising counterparts. But still, both groups had about the same number of periodical impairments. Also, more of the exercisers had to be hospitalized at one or more times, perhaps due to underlying medical conditions that were discovered over the course of the study. And some of the participants who underwent health education started exercising on their own account as well, which makes the distinction between the groups less clear.
Still, the findings of the study are valuable. For starters, they show that it is never too late to become physically more active and reap the benefits. Second, they demonstrate that even low-impact exercise like walking can be effective if done regularly. For seniors, in particular, it is important to focus, besides weight control and muscle and bone health, on flexibility and gait – not only to maintain physical fitness but to counteract mental decline as well.
As a number of studies have found, exercise can play a crucial role in the prevention of age-related dementia such as Alzheimer’s disease. That in itself should motivate everyone to take a few extra steps…
