The best factor for determining the activity levels of school children is the extent of participation in organized
sports and physical education classes. Considering that teenagers spend most of their time at school, physical
education and sports classes should significantly contribute to their physical and mental development (Johnston et
al., 2007). The physically excessive fat mass and the mental tiredness of teenagers during their adolescence could be
minimized with the help of physical education activities. Physical health gained during childhood and adolescence
and maintained lifelong, is essential for the body to function at the optimum level (Baltacı, 2008). Physical
education is a training process which realizes the optimum development for the benefit of the individual and of
society through large muscle activities, without damaging the individual’s physical, mental and social integrity
(Koç, 1998).
