Exercise Makes the Grade

By Richard Peatman, Pharm D, Meadow Vista Pharmacy
Want your child to do better in school? Make sure exercise doesn't get the short end of the stick. A review of 12 exercise studies recently reported in Archives of Pediatrics & Adolescent Medicine underscored how important exercise is for the brain, not just the body. It found that children who regularly exercised tended to do better in school.  These were a few of the research findings:
• Middle school kids who exercised vigorously for at least 20 minutes, three days a week, achieved higher grades over two semesters than students who did not intensely exercise.
• Elementary school children with good aerobic fitness were more likely to excel in reading and math.
• Overweight children who exercised 40 minutes every day for 15 weeks scored better in tests of executive function – the "conductor" of cognitive skills – than overweight kids who only exercised 20 minutes.
 Researchers point to several possible reasons for these promising findings. For one, physical activity increases the flow of blood and oxygen to your brain. And, as you may already know, exercise boosts endorphins. These are hormones in the brain that improve mood. They may give kids an extra lift for tackling academic challenges. Exercise also promotes development of a protein that acts a little like Miracle-Gro® for your brain. Brain-derived neurotrophic factor (BDNF) is found in areas of the brain that are critical for learning, memory, and higher thinking.
  Unfortunately, many children today aren't getting the physical activity their bodies and brains so desperately need. The Centers for Disease Control and Prevention (CDC) says that children and teens need a minimum of 60 minutes of mostly aerobic, physical activity each day. Aerobic activities are the ones that get your heart beating faster, such as fast walking or running. 
 What if your child isn't into sports or shuns the idea of physical exercise altogether? Then, it's up to you as a parent to help make exercise become a habit. Here are some ideas:
• Do what you can to set a positive example.
• Find fun activities you can enjoy together as a family. Hike, go bike riding or play hide-and-go seek.
• Give gifts that promote physical activity, not just sedentary ones.
• Help your child find physical activities he or she enjoys. Remember: it's not the same for everyone. Some like team sports. Others enjoy individual activities such as swimming or skating.
• Set up an electronics-free time each week.4
 With teens, exercise may be an even tougher sell, but remember that exercise doesn't have to be just for jocks.  There are countless ways to hook a kid into being more active. Think of potentially more popular activities like the video game, DanceDance Revolution. Or maybe hip-hop, martial arts, or mountain biking is the way to go.
