A sample of 240 observed pupils was divided into two groups. One group (25 boys, 25 girls) with a high and the second one (25 boys, 25 girls) with low intensity physical activities. The intensity of physical activity was diagnosed by means of questionnaires and quantified in output of energy given as a percentage of their basic metabolism. The results in other methods, such as the physiological tests (oxygen consumption; Ruffier's test), psychological tests (need for achieve ment, EPI) and several motor abilities tests; confirm that children with intensive physical activity attain significantly: - better performances in most of the motor abilities tests, - higher values in oxygen con sumption; nonsignificantly: - favourable indices in the achivement motivation test (net motivation). The final analysis recommends that teachers of physical education encourage positive attitudes towards physical activity in children for improvement of their regular physical activity (health and education be nefits). Furthermore, they should support and de velop the spontaneous physical activity of children together with the parents.
