With this objective, 80 children aged 10 to 12 years (39 boys, 41 girls) filled a diary of their activities in a structured format and simultaneously weard an accelerometer for one to three days. The activities of every subject were expressed in counts per minute (cpm). The levels of physical activity (PA). Were classified as sedentary PA / light PA / moderate PA and vigorous PA. Results: 26 different activities were documented. In most of them the difference between boys and girls was weak and no significant. The only vigorous PA was to run. In category "moderate PA" the cpm of plays outdoor was significantly less than those of sports and school gymnastic (p 0,007)- These results can serve as guiding for establish a scale of values for global evaluation of PA in children schoolers.
