Moreover, the intensity and the duration of these activities that use the aerbico metabolism have great importance in the effectiveness of the alterations in the corporal composition (GUEDES, 1997). Siegel (1987) showed the importance of the games with races for the children as an alternative to improve the cardiovascular system.

The obesidade has direct relation with sedentary behaviors as, to pass much time attending television or in the use of the Internet (HAGER, 2006). Then, it is front to this reality that the habit to practise the physical activity can assist in the combat to this illness that reaches millions of people in the whole world.
