Interactive Exercises Improve both Physical and Cognitive Functions

There is a new way to combine physical and mental exercise—two important factors to prevent accidents and increase mobility in older adults. The key to better mobility is in digital gaming that integrates physical exercise—also called “exergames.” These are interactive video games that allow older adults to maximize their body functions in digital environments, to their physical and cognitive benefit.

The study, conducted over two years, aims to identify the relationship between exergames and their improvement on the health of adults 50 years or older. And the result? According to Dr. Anderson-Haley of the Health Aging and Neuropsychology Lab at the Union College in Schenectady, NY, the research shows that virtual gaming exercises, such as cybercycling, not only enhances physical wellness but also protects the cognitive function.

Exergames allow older adults to divert their attention in the 3D sceneries presented. Without aversive environmental factors present, older adults get to focus on the game and, ultimately, improve their well-being.

Unfortunatley, only 14% of adults between 65 to 74 years old ever get to do exergames. For those over 75 years old, only 7% engage in regular exergames.

The study was conducted among 101 older adults from 58 to 99 years old. They were made to ride stationary bikes with a virtual reality display in the backdrop, a 3-d tour, and a virtual race against a “ghost rider”. The participants then rode on the bike thrice a week.  Another group was made to ride a stationary bike without the virtual environment.

The researchers found that regular exercises in the cybercycle produced positive results in executive functions, such as planning, memory work, and problem solving—all after just a month in the cybercycles. Despite the fact that there was no difference in the two groups, the group which had a virtual gaming experience showed substantial cognitive benefit.

The inevitable conclusion, according to the study, is that older adults who choose interactive exergames will have the benefit of traditional exercise, plus better cognitive performance.

Older Adults and Salt Intake

While it’s important for people of all ages to watch what they eat, older adults have special dietary concerns that should be paid special attention to. A new study, recently published in Neurobiology of Aging, has determined that high-sodium diets combined with low physical activity can raise serious health issues for adults aged 65 and older.

A decline in cognitive function and an increased risk of developing heart disease are among the risks.

“Our results show it’s a combination of high salt intake and low physical activity which declined cognitive function,” Study lead Dr. Alexandra Flocco from Toronto’s Baycrest Hospitals’ Kunin-Lunenfeld Applied and Evaluative Research Unit told the Toronto Sun. “The message is if you’re not active, make sure you cut back on your salt intake.”

The study analyzed 1,262 healthy older adults between the ages of 67 and 84, tracking their nutritional intake (and sodium consumption) as well as their physical activity for a period of three years. The daily average intake among participants varied greatly, from 2,263 to a staggering 8,098 milligrams. Health Canada recommends people aged 14 years and older consume no more than 2,300 milligrams of salt each day. The American Heart Association recommends that people living with high blood pressure limit their intake to 1,500 miligrams per day, which is less than ¾ of a tablespoon of salt.

Nearing the completion of the study, the participants were given an exam that measured their cognitive decline. Scored showed that participants with the lowest average daily salt intake suffered less cognitive decline and instances of heart disease than their counterparts who ingested a higher daily salt intake.
Sodium is an essential nutrient but it should not be over-consumed. Canned and pickled foods are incredibly high in sodium, as are certain salad dressings, cheeses and sauces. It’s important to check the nutritional information on food packaging before buying.
