In today's society, having a good education guarantees a stable and prosperous future. A lot of pressure is put on students to get excellent grades, resulting in them having less time for extracurricular activities, such as sports. However, does constant physical activity guarantee improved academic performance among peers in Marianopolis? Research has shown that being involved in fitness improves grades. People who do not participate in extracurricular activities at school tend to get lower grades than those who participate in sports. This topic is particularly interesting for students. He encourages them to play more sports so their grades can go up. In fact, we believe that physical activity actually has a positive consequence on academic performance. In fact, research studies show a lot of correlation between physical activity and good grades in school. In this sense, a very interesting study by Professor Eric DeMeulenaere demonstrates that students who participate in an extracurricular activity such as sport increase their chances of achieving greater academic success. Confidence has also been shown to play a significant role in students' academic standing. According to DeMeulenaere (2010), self-confidence can greatly encourage adolescents to participate in a sports team. Therefore, their academic performance will increase. This is relevant to our study because we are also interested in the happiness and confidence of Marianopolis students. Likewise, a study conducted by several researchers demonstrates the positive effect that physical education lessons could have on grades. Once again, physical activity leads to higher self-esteem during school. (Sollerhed 2005). Another study completed in 2005 demonstrated a strong correlation between fit... middle of the paper...
