Two new studies examined whether kids that have serious behavioral disorders or who may be at a higher risk for depression might benefit from exercise. The results showed positive outcomes for both sets of children participating in the studies.
For one study, researchers focused on children and teenagers with conditions that included autism spectrum disorders, attention deficit hyperactivity disorder (ADHD), anxiety and depression.
They looked at whether structured exercise during the school day -- in the form of stationary "cybercycles" -- could help ease students' behavioral issues in the classroom. Cybercycles are stationary bikes equipped with virtual reality exercising games.
Over a period of seven weeks, the study found it did. Kids were about one-third to 50 percent less likely to act out in class, compared to a seven-week period when they took standard gym classes.
Lead researcher, April Bowling, said the results were meaningful.
"On days that the students biked, they were less likely to be taken out of the classroom for unacceptable behavior," said Bowling, who is now an assistant professor of health sciences at Merrimack College in North Andover, Mass.
"That's important for their learning, and for their relationships with their teachers and other kids in class," she said.
The study was done at a school that enrolls kids with behavioral health disorders, many of whom also have learning disabilities. Their usual gym classes focused mainly on skill building, with only short bursts of aerobic activity at most, according to the researchers.
For seven weeks, 103 students used the stationary bikes during their usual gym class -- twice a week, for 30 to 40 minutes. Their classroom behavior was tracked and compared with a seven-week period without the bikes, when they had gym class as usual.
Overall, the study found, the students were better able to control their behavior in the classroom during the stationary-bike trial.
Another recent study from Norway, adds more evidence to the benefits of exercise in children. Researchers from Norwegian University of Science and Technology measured activity levels in 800 six year olds who were asked about their exercise habits and any depressive symptoms. Follow ups were recorded at 8 and 10 years of age. Overall, children who exercised more, at a moderate to vigorous intensity, showed fewer depressive symptoms years later.
While the researchers noted that exercise alone isn’t a cure for depression, it has been shown to alleviate some depression symptoms.
“I think that physicians, parents and policy makers should facilitate physical activity among children,” says Tonje Zahl, the study’s lead author. “The focus should be on physical activity not just for the here and now benefits, such as improving blood pressure, heart rate and other physical benefits, but for the mental health benefits over the long term,” she says. All children should be targeted for this, she adds.
Experts say there are several theories as to why exercise may help kids control their behaviors. Bowling suggests that exercise may redirect the brain away from worrying.
Another theory is that exercise affects neurotransmitters -- chemical messengers in the brain that help regulate mood and behavior.
Bowling notes that it’s unfortunate that many schools are focusing so much on academics that they are cutting out gym and recess.
"If we really want our kids to do well, they need more movement during the school day, not less", she said
If children are unable to get the exercise they need at school, there’s always active playtime, walking and sports after school that can help provide some of the same benefits.
Both studies were published in the online journal, Pediatrics.
