Latest Senior Health News
Moderate-intensity physical activity has been shown to be good for your health. But, this study suggests that seniors should also be encouraged to engage in lower-intensity activity whenever they can, study lead author Paul Loprinzi, an assistant professor of exercise science and health promotion at the University of Mississippi, suggested in a news release from Oregon State University. Loprinzi was at Oregon State University at the time of the study.
"For example, instead of talking on the phone in a seated position, walking while talking will help increase our overall physical activity level," he added.
For the study, researchers reviewed information from a U.S. national survey done between 2003 and 2006. They found that high amounts of low-intensity workouts provided significant benefits for people older than 65.
Light activity includes things such as walking, slow dancing, household chores and leisurely sports such as table tennis. Seniors who did 300 minutes or more per week of light activity were 18 percent healthier than seniors who didn't. They also had less body fat and smaller waists than their less active peers.
The researchers also found that the people getting 300 or more minutes of light activity also had better insulin levels, and a lower risk for chronic disease.
The study was published in the American Journal of Health Promotion.
There are 168 hours in a week, the study's co-author Brad Cardinal, a professor at Oregon State University, pointed out in the university news release. That means 300 minutes is about 3 percent of that time, he noted.
"You get a nice array of health benefits by doing five hours of light physical activity per week," Cardinal said.
Light exercise tends to be more appealing to seniors and typically does not require a doctor's approval, Cardinal added.
