Virtual reality-equipped bikers exercise their brains, too

Riding an exercise bike equipped with gaming features was better for the brain than riding a normal cycle, a study from Union and Skidmore Colleges found.

The study, which was published in the February issue of the American Journal of Preventive Medicine, involved 79 people ages 58 to 99 from retirement communities who had access to an exercise bike. Forty-one of the 63 who completed the study rode a regular recumbent exercise bike an average of three times a week for three months while 38 rode a special exercise bike with a virtual reality display. The "cybercycles" were equipped with screens that enabled riders to feel as if they were on a 3-D tour and racing a ghost rider based on their last best ride.

Story continues below.

The exergamers had better executive function when the study ended, and fewer progressed to mild cognitive impairment, often a precursor to dementia. They also had higher levels of a brain growth factor in their blood, possibly a sign that the exercise was stimulating changes in the brain.

Cay Anderson-Hanley, a Union College neuropsychologist who led the study, said cybercyclists did not exercise harder than the others, so the cognitive improvements likely were related to the experience of making decisions in a virtual environment while exercising.

Free pamphlet on drug-abuse treatment choices is available

The National Institute on Drug Abuse has a new, free pamphlet for families struggling to choose a drug-treatment program.

The eight-page booklet, "Seeking Drug Abuse Treatment: Know What to Ask," describes the principles of care and how to evaluate a program.

The brochure recommends asking about the scientific basis for the program, how it is tailored to individual patients' needs, the usual duration of treatment, and how 12-step programs fit in.

The booklet also describes available medications and behavioral therapies, the reality of relapse, and the role of community-level support.

A copy can be ordered by calling 1-877-643-2644 or downloaded from www.drugabuse.gov/publications/seeking-drug-abuse-treatment. - Marie McCullough
