Keep Moving to Prevent Major Mobility Disability

Journal of the American Geriatrics Society Research Summary

Having trouble getting around on your own—such as difficulty walking, climbing steps, or being able to get in and out of a chair—can lead to physical disability and losing your independence.

According to research, being physically inactive is the strongest risk factor for disability as we age.

We know that physical activity has proven health benefits, especially moderate-to-vigorous physical activity such as walking to the store or many types of gardening. But perhaps surprisingly, we don’t know much about the benefits of lighter forms of physical activity or the effects of spreading our physical activity throughout the day. Understanding the benefits of moving more often and engaging in even lighter forms of physical activity is important for older adults’ health. These types of physical activity may be easier for older adults to practice regularly, especially those who are frail.

That’s why a team of researchers created a study to examine the effects of performing light physical activity and moderate-to-vigorous physical activity on older adults. The researchers were interested in studying how participating in these different intensities of activity, and whether a person spreads their physical activity throughout the day, affects the chances for developing a major mobility disability. The participants in the study were older adults who had challenges with physical function and who participated in the Lifestyle Interventions and Independence for Elders (LIFE) study. The researchers published their study in the Journal of the American Geriatrics Society. Continue reading

Slower Walking Speed May Predict Future Mobility Problems

Journal of the American Geriatrics Society Research Summary

Being able to walk outside for several blocks at a leisurely pace plays an important role in living a vibrant, healthy life. Walking short distances allows you to get the physical activity you need, live independently, go shopping, access health care, and engage in a social life.

Being able to walk at even a slow speed is essential to all these benefits—but walking too slowly may foreshadow future problems that could prevent you from being fully mobile.

Until now, there has been no ideal way for healthcare providers to measure walking ability, since it involves more than just walking speed. It also is about how you deal with your environment (such as uneven pavement) and demands on your attention (such as traffic, other pedestrians, and street crossings).

In a new study, researchers assessed ways to measure complex walking tasks to learn more about early, subtle changes in walking. Their study was published in the Journal of the American Geriatrics Society.

In their study, the researchers examined whether performance on complex walking tasks involving both physical and mental challenges predicted a higher risk for an inability to walk one-quarter mile (roughly four blocks). The researchers suspected that these complex walking tasks would be more strongly tied to the risk for mobility problems than simple walking.

The researchers studied information from the Health Aging and Body Composition (Health ABC) study, which enrolled black and white adults in Pittsburgh and Memphis from 1997 to 1998. The participants were 70 to 79 years old when they entered the study, and they had no difficulty walking a quarter mile or climbing 10 steps without resting. Continue reading

Pedometers Allow Healthcare Practitioners to Track Physical Activity for Older Adults

Loss of mobility is one of the leading causes of a decreased quality of life, loss of independence, and even death for us all as we age. Since physical activity is the key to helping prevent mobility loss, it’s important to maintain a decent level of physical activity for as long as possible.

Researchers for a new study published in the Journal of the American Geriatrics Society now suggest that we don’t know much about how the duration and intensity of physical activity affects the development of major mobility problems.

In their study, the researchers tracked the activity of 1,590 adults between the ages of 70 and 89. To measure the participants’ activity levels, they were asked to wear a pedometer, which is a research instrument that measures how many steps you take. Participants wore the devices for at least three days for 10 hours a day while going about their daily routines. None of the participants had major mobility problems at the start of the study.
