“The goal is to get kids moving throughout the school day,” Hillman said. While he grants that academic class time is also important, “clearly the academic at this point is at the cost of being physically active, and I think there has to be some level of accommodation.”
Hillman also cautions that physical activity alone has not been shown to increase cognitive performance. A slow walk for example, does little to make anyone smarter. What is definitely tied to brain health, Hillman said, is physical fitness.
“Effects are actually found in the brain,” Hillman said. “We find higher fit kids have differential brain function than lower fit kids.”
The prefrontal cortex and the hippocampus of physically fit children are better developed than those of less fit children, Hillman said. These two brain structures control many of the abilities that lead to high academic achievement: long-term memory, self-regulation and goal making, among other key functions.
Hillman, who is advising the U.S. Department of Health and Human Services on the latest exercise research for the 2018 revision of the department’s recommendations for physical fitness, said that evidence of a connection between fitness and brain function has mounted steadily over the years.
A 2009 Stanford University study found that fifth, seventh and ninth grade students in California who passed the state physical fitness test and those whose fitness improved between fifth and seventh grade scored better than their less fit peers on the state’s standardized tests. A 2013 study of nearly 12,000 Nebraska students also found that aerobically fit students were more likely to pass the state’s standardized math and reading tests, regardless of their weight or socioeconomic status. Another 2013 study that randomly assigned 8- and 9-year-old Illinois children to a nine-month after-school fitness program found that the kids whose fitness improved also got better at paying attention and ignoring distractions. They also improved to young-adult levels in their ability to regulate their behavior.
School districts that have added more physical activity to their daily schedules in the hope of improving academic performance have also seen measurable changes. When a Ft. Worth, Texas school made a much-publicized switch for its kindergarten and first-grade students from one 20-minute recess a day to four 15-minute recesses — or an hour, total —it found that students were more focused in class and that teachers were able to move through curricular material faster. Off-task behaviors in class decreased by 25 to 35 percent and students’ body mass indexes (weight divided by height) stabilized or decreased, said Deborah Rhea, a professor at Texas Christian University and the lead researcher on the longer-recess initiative.
“We’re at least getting closer to a healthy environment that’s conducive to learning for teachers and for kids,” Rhea said of the multiple 15-minute breaks.
All of this research comes after nearly three decades of school policies that decreased recess time amidst fears that the unstructured time led to student fights or took time away from students’ focus on passing standardized tests. One 2007 survey by George Washington University found that 20 percent of a representative sample of districts had decreased recess time by an average of 50 minutes a week and 9 percent had reduced physical education time by an average of 40 minutes.
Today, middle and high schools are still the least likely to have daily physical education or recess. Forty-one states require physical education at the middle school level, according to the 2016 annual report by SHAPE, and 46 require it in high school. But only 15 states include a specific amount of time middle school kids must spend in physical education per week; only six states have a similar time requirement at the high school level. Most states don’t require middle or high schools to offer recess at all.
The idea that young children need to move a lot is fairly intuitive to anyone who has ever spent time in the company of a child under age eight. But older children need movement too — at least an hour a day according to federal guidelines — and they are getting a lot less of it. Fewer than one in three high school students — 27 percent in 2015 — are getting the recommended number of minutes of daily exercise, according to data from Child Trends, a nonprofit research organization focused on youth issues. Girls, black students and Hispanic students get less exercise than white boys.
Moreover, budgets for physical education equipment and supplies are tiny; the median is just $764 per year per school, according to SHAPE’s 2016 report.
Many blame the federal education law known as No Child Left Behind (NCLB), which was enacted under former President George W. Bush, for the dearth of physical education funds and focus. “There was no phys ed in NCLB,” Wright said. “Teachers were cut, budgets were cut, some states repealed state polices on phys ed. There were definitely some pretty serious unintended consequences.”
Several factors seem to be leading educators and policymakers to begin addressing those consequences: the current backlash against standardized testing, the ever-improving understanding of brain science and the influence of national campaigns like former First Lady Michelle Obama’s Let’s Move! and SHAPE’s efforts to influence national legislation, such as ESSA.
In Wisconsin, for example, the state education department oversees a program called Core 4+, which features inexpensive interventions to increase movement throughout the school day. The program is now in place at 450 schools serving over 300,000 students. Appleton, which has seen several of its schools receive national recognition for their efforts in this area, is one of the cities participating in Core 4+, better known by school leaders here as “active kids, active classrooms.”
The idea of adding so many minutes of movement to the day, especially during class, was initially met with some resistance, said Mikki Duran, who oversees Appleton’s physical education department. Teachers told her they didn’t have time. Duran’s answer was that taking time to move would actually result in more focused time to learn. Once they tried it, she said, most teachers became quick converts.
Today, every school in Appleton has its own program, each aimed at increasing physical activity and fitness. At Horizons Elementary, at least 40 of the school’s 350 kids start every day in the school gym playing a game like “Castle” — a kind of dodge ball, capture-the-flag mash-up. The gym stays open all day for teachers or aides wanting to bring kids down to run a lap and burn off some excess energy. There’s also a running club, and the teachers themselves often start staff meetings with a few laps around the school track.
The physical education teacher here, Carrie Michiels, has also introduced “Fit in 15” breaks for classroom teachers for the days their students aren’t scheduled to take a full physical education class.
“Kids are more alert, more involved” after the breaks, said fifth grade teacher Gina Dresang, a 23-year veteran. “It can be tricky. Once they get up, they can get silly and it takes time to get them back on task, but the benefits outweigh the downsides.”
For several educators in Appleton, the pursuit of better fitness has also become personal. After learning more about the effects of physical fitness on the brain a few years ago, Kaleidoscope principal Al Brant decided he needed to make a change. Heavy-set all his life, he opted for gastric bypass surgery, improved his diet and started exercising. He lost 120 pounds and spent part of last summer on a trip with his daughter to climb 19,300 feet to the top of Mt. Kilimanjaro. The photos of his trek decorate his office walls along with pictures of his bow-hunting expeditions.
“It changed my attitude about promoting phy-ed,” Brant said of his experience.
Now, he wants his students to know about personal fitness long before they become overweight adults. He has prioritized movement at his school, offering strong support to the physical education teachers here. Staff meetings are now regularly interrupted as teachers get up and move for a few seconds or minutes, just like the “brain breaks” offered in most classrooms. Brant has also fully bought-in to the idea of movement during class. Last spring, he authorized the $9,072 purchase of 144 wobbly chairs — the ones the kids appear to love even as they insist they don’t.
The change in students’ ability to focus, especially in the kids who struggle with attention deficit disorder, has been noticeable, he said. He advises other principals thinking of making a shift at their schools to find a few adult champions who can help explain the brain science and offer practical advice to other teachers on how to make movement a bigger part of the day. He also says it’s worth having physical education options with clear curricula and learning standards. The more kids understand about what they can do to be fit now, the more likely they’ll be able to stay fit as adults.
Indeed, said Wright, the national advocate from SHAPE, the biggest pay-off of more physical education and recess for America’s schoolchildren would be fitter adults.
“Students who are physically active and healthy have higher test scores, lower rates of discipline referrals and increased focus in the classroom,” she said. And while that’s important, Wright also emphasized the health and wellness value of high quality physical education: It teaches kids “how to be physically active for a lifetime.”
