Exercise! Sedentary Lifestyle More to Blame for Decline With Age Than Aging
Just spotted this one:
Running Into Old Age
Ian McMahan, Apr 22, 2015
While some loss of strength is inevitable, the researchers found that older athletes who participated in exercise programs showed significantly more muscle strength that people of similar age who didn’t exercise. Maintaining muscle strength can be a key component of successful aging, as past research has shown that its loss in seniors is correlated to an increased risk of falling, a significant cause of age-related trauma.
In fact, contrary to popular belief, older adults are not at an overall increased risk of injury when participating in exercise activity; rather, regular exercise puts them at diminished risk compared to their sedentary peers. The 2014 study noted that regular movement can strengthen bone density, which protects against osteoporosis, while a separate study, published in 1985 in the Journal of Applied Physiology, found that it can also help reduce the risk of arthritis and injuries to tendons and ligaments.
Even for the adults who haven’t exercised in years or even decades, research suggests that late is still better than never. A 2014 study in the British Journal of Sports Medicine found that among a group of people aged 55 to 73, those who had exercised at least once a week subsequently had lower rates of chronic disease, depression, and “physical or cognitive impairment” than their more sedentary peers. However, the subjects that began the study as sedentary but began exercising regularly sometime over its eight-year follow-up period had outcomes that were almost as good.
So keep on busting in.
