Infants of mothers who engaged in aerobic exercise during pregnancy tend to show better motor development at 1 month compared with infants of nonexercising mothers, according to authors of a new study. The researchers believe that aerobic exercise during pregnancy could be a hedge against childhood overweight and obesity.
Researchers analyzed data from 60 healthy mothers (ages 18 to 35, with an average age of 30) and their infants. During their pregnancies, 33 women participated in 45-50 minutes of supervised aerobic exercise, 3 days a week. The remaining 27 women in the control group were asked to engage in a 50-minute supervised stretching and breathing program 3 days a week, but were otherwise advised to continue with “normal” activities. The infants of both groups were then evaluated for motor skills development at 1 month using the Peabody Developmental Motor Scales, second edition (PDMS-2), a tool that tests reflexes, locomotion, and a child’s ability to remain stationary. The measure also provides a composite score, known as the Gross Motor Quotient (GMQ).
Exercise is just as good for the brain as it is for the body, a growing body of research is showing. And one kind in particular—aerobic exercise—appears to be king.
“Back in the day, the majority of exercise studies focused on the parts of the body from the neck down, like the heart and lungs,” says Ozioma Okonkwo, assistant professor of medicine at the University of Wisconsin School of Medicine and Public Health. “But now we are finding that we need to go north, to the brain, to show the true benefits of a physically active lifestyle on an individual.”
Exercise might be a simple way for people to cut down their risk for memory loss and Alzheimer’s disease, even for those who are genetically at risk for the disease. In a June study published in the Journal of Alzheimer’s Disease, Okonkwo followed 93 adults who had at least one parent with Alzheimer’s disease, at least one gene linked to Alzheimer’s, or both. People in the study who spent at least 68 minutes a day doing moderate physical activity had better glucose metabolism—which signals a healthy brain—compared to people who did less.
Aerobic walking programs for the management of knee osteoarthritis (OA) and recommendations for falls assessment and prevention are among the clinical practice guidelines recently approved by the federal Agency for Healthcare Research and Quality’s National Guideline Clearinghouse (NGC).
The NGC’s update of the Ottawa Panel evidence-based clinical practice guidelines for aerobic walking programs in the management of osteoarthritis focuses on the efficacy of various programs for adults over 40 with knee OA, and analyzed outcomes for walking programs that feature any combination of strength training, health education, behavioral components, and multicomponent exercises. The review evaluated outcomes based on pain level, quality of life, and functional status.
