Chapter+2

In this chapter, we are going to review a few related articles to afford a clearer understanding of this study. We will explain that a physical activity and exercise are activities that use large muscle groups, such as walking, running, or swimming cardiovascular adaptations that increase exercise capacity, endurance, and skeletal muscle strength. An important interrelationship exists between the total dose of activity and the intensity at which the activity is performed. Now, we have defined the concept of benefit in healthy physical activities and exercise and factor participate in physical activity and exercise.

Usually students always hear that sport helps us to become healthier. ** Male students prefer ** to do physical exercises like sport because they can improve their body shape. The percentage of body weight which is fat, muscle and bone, that is genetic but also influenced through exercise and diet. It is because the tone of muscles becomes more ** tough ** and do these activities can loose our weight. From this, our life can be healthy working of the heart, blood and blood vessels. Helps one to continue to lead an active lifestyle and make our look and feel good about our self. Where, students can more confidently and have a strength to face others people. Beside that, its can provides our life with good health because those who are active generally cope better with illness more to stronger heart and lungs. Steven Redgrave had said “you can be fit but not necessarily healthy.” (Steven Redgrave, 5x Olympic champion gold medallist who suffers from diabetes and ulcerativecolitis.

Schools at all levels must develop and encourage positive attitudes toward physical exercise, providing opportunities to learn physical skills and perform physical activities, especially those that can be enjoyed for many years. (J Am Coll Cardiol, 1993). The school curriculum should not overemphasize sports and activities that selectively eliminate children who are less skilled. Schools must teach the benefits of exercise and the development and maintenance of exercise and exercise conditioning throughout life. Some studies demonstrate that organized school programs are not only feasible but successful.In addition; these programs can be used to promote proper nutrition and cigarette smoking prevention and cessation. Factor of participation in physical exercise among a student is lightly because the sociological factors where they get the supportive from their parents, family and social surrounding. The other factor is facilities, that if the facility is not enough to the students and it can make less participation among the students to do physical activities.  Environment factor also can influent the participation of students. Accessibility, opportunities, and aesthetic attributes had significant associations with physical activity. Weather and safety showed less-strong relationships Physical environment factors have consistent associations with physical activity behavior. Further development of ecologic and environmental models, together with behavior-specific and context-specific measurement strategies, should help in further understanding of these associations. Prospective studies are required to identify possible causal relationships.
