It is a known fact that physical activity improves overall health.

Not only does it improve circulation, increase blood flow to the brain,

and raise endorphin levels, which both help to reduce stress, improve 【M1】_________

mood and attitude, and calm children, physical activity may also help

students achieve more academically. Physically fit students are more 【M2】_________

likely to miss school, partake in risky behaviors, get pregnant, or

attempt suicide, which all associated with better outcomes in school. 【M3】_________

Many studies have demonstrated the positive effects of physical

education and physical activity on school performance. Several studies

have stated that providing increased time to physical activity can lead to 【M4】_________

better concentration, reduced disruptive behavior and higher test scores

in reading, math and writing.

One specific study that addressed this issue was done by Sallis et al.

when they implemented a program called Project SPARK in which it 【M5】_________

provides physical activity during class by containing health-fitness 【M6】_________

activities like jumping rope and aerobic dance so well as sport-fitness 【M7】_________

activities like soccer and Frisbee games and focuses on training teachers

to implement the curriculum. The program also promotes physical

activity outside of school and rewards children in engaging in physical 【M8】_________

activity with their families. Results of the study show that when teachers

were trained to use Project SPARK there were significant differences

between the experimental and control groups in language, reading, and

other basic skills. This study shows that organize physical activity can 【M9】_________

impact student performance even though in short-term experiments. 【M10】________
