Schools are a great place to provide students with daily physical movement and to teach the essentiality of overall physical action for well-being. Shockingly, most people do little or no general physical activity while at school. Budgetary obligations and pressure to raise test scores have led school authorities to address the value of physical education and other physical activity programs. This has resulted in a significant reduction in the time available for physical education and, in some cases, physical activity projects at school have been completely eliminated. Exercise not only helps individuals' physical health, but also helps their mental attitude, which can help them improve in school. Studies show that high school students who do cardiovascular exercises, such as running and swimming, have larger brains (Henshaw 3). A school study indicated that a 30 minute walk on a treadmill improved students' critical thinking skills by 10% (Henshaw 6). This is a full letter grade, so the effect is clearly not tiny. A recent study shows that on average kids do 29 minutes of physical activity a day; while girls do only 18 minutes of physical activity a day (Henshaw 2). This time is extremely less than the 60 minutes recommended by health officials. When children and adolescents participate in at least 60 minutes of physical activity consistently, numerous health benefits occur (Henshaw 4). Some of these are that it increases self-respect and decreases stress and anxiety. In addition to these known health effects, physical activity also has beneficial effects on academic performance. “Among elementary school students, 40 minutes of daily exercise increased IQ by a neurotrophic factor derived from a paper medium. John J. Ratey, Ph.D. says, “BDNF is like fertilizer for the brain” (Lawrence 4). He also states “Without it, our brain cannot absorb new information or create new cells” (Lawrence 5). In one study, analysts examined the brains of individuals who exercised for an hour a day, three days a week, for a period of six months. They found that the hippocampus, the part that controls memory, was growing. The training actually grew the brains of the study participants, which helped them in the concentration and memory area of Beqiri 5 (Asp 2). Not all exercises affect the brain the same way. There have been studies linking certain exercises to increase brain activity. An example of this is high intensity training linked to immediate excellent mental performance (Asp 3). Slow aerobic exercise is linked to the retention of information over time (Asp 4).
