Aerobic Exercise May Mildly Delay or Slightly Improve Alzheimer’s Disease Symptoms

Journal of the American Geriatrics Society Research Summary

Alzheimer’s disease (AD) is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults.  There is presently no cure for the condition, though treatment options are available. Today, some 5.3 million Americans live with AD, and it is now the sixth leading cause of death in the United States. The number of older adults who will develop AD is expected to more than triple by 2050.

Geriatrics experts have suggested that exercising can improve brain health in older adults. The World Health Organization (WHO) has recommendations for how much older adults should exercise. They suggest that older adults perform 150 minutes a week of moderate exercise (such as brisk walking), 75 minutes a week of vigorous aerobic training, or a combination of the two types. The WHO also recommends older adults perform muscle-strengthening exercises on at least two or more days a week.

However, not all studies of exercise and older adults have proven the benefits of exercise. We don’t know for sure whether exercise slows mental decline or improves older adults’ ability to think and make decisions. Continue reading →

Measured with Fitness Trackers, Light Intensity Physical Activity Linked to Lower Mortality in Women 63 to 99

Experts say that a lack of physical activity leads to age-related weakness and poor health in older adults. Official guidelines suggest that healthy older adults spend at least 2.5 hours every week doing moderate activity (such as brisk walking), or at least 1.25 hours per week doing vigorous exercise (such as jogging or running).

Unfortunately, many older adults are not physically able to perform either moderate or vigorous intensity exercise. Researchers created a study to learn more about how much exercise older adults are able to perform, and how that exercise affects their health.

The research team studied 6,489 female participants aged 63 to 99 years old. The researchers published their findings in the Journal of the American Geriatrics Society.

The participants agreed to take in-home exams, answer health questionnaires, and wear accelerometers (devices similar to fitness trackers). The participants also kept sleep logs.

The study was conducted between 2012 and 2013. The researchers reviewed death certificates as of September 2016 to learn how many participants had died. Continue reading →

For Older Adults with Diabetes, Losing Weight through Diet and Exercise Can Improve Blood Circulation in the Brain

Type 2 diabetes affects blood circulation. The disease stiffens blood vessels and reduces the amount of oxygen that circulates throughout your body. This includes your brain. When blood flow in the brain is impaired, it can affect the way we think and make decisions.

People who have type 2 diabetes are often overweight or obese. These are conditions that may also be linked to cognitive problems (problems with thinking abilities). Lowering calorie intake and increasing physical activity are known to reduce the negative effects of type 2 diabetes on the body. However, the effects of these interventions on cognition and the brain are not clear.

Recently, researchers examined information from a 10-year-long study called Action for Health in Diabetes (Look AHEAD). In this study, participants learned how to adopt healthy, long-term behavior changes. In their new study, the researchers focused on whether participants with type 2 diabetes who lowered calories in their diet and increased physical activity had better blood flow to the brain. The researchers published their findings in the Journal of the American Geriatrics Society. 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.
