Damage of Sedentary Lifestyle in Adult Life Because of The Lack of Practice of Activities in Physical Education Discipline in the Contemporary World

Sedentarism is a serious public health problem, as physical inactivity over the years can lead to several noncommunicable chronic diseases, which in Brazil and in the world have shown a high mortality rate. In this context, the objective of this article was to discuss the impacts of a sedentary lifestyle on the health of the adult population due to the lack of physical activity at school age, especially in Physical Education classes, considering that the regular practice of physical exercises is a of the most effective alternatives against this problem. Studies show that health and quality of life awareness must be initiated within classrooms, which must be cultivated and worked on in a didactic-pedagogical context, with the active participation not only of students, but also of their families, in the construction of the school's pedagogical political projects. However, with technological development, increasing urbanization and the increase in violence, many children and young people have reduced their affinity for sports and physical activities in general, which can have bad consequences for their future. Therefore, Physical Education becomes an increasingly important subject for students to be aware of the benefits of practicing physical activities in childhood/adolescence. But for it to become more significant, is necessary for there to be changes in attitudes, even by teachers, regarding the improvement of classes, to help combat sedentary lifestyles within the school environment, enabling the formation of active, critical citizens who are concerned with your long-term health and well-being.
