Results: The average age of participants was 17.04 ± 1.5 years. Levels of physical activity with intensity of more than 2 METs was significantly higher (P < 0.05) in boys (13.44 ± 9.7 Met hours a day) than in girls (9.60 ± 9.2 Met hours per day) and daily energy expenditure in infect activities over more than 2 METs were significantly higher (P < 0.05) in boys (891.72 ± 740.8 kcal) than in girls (557.27 ± 567 kcal). Also, significant difference in the amount of daily activity with an of intensity more than 2 METs and the consumable energy caused by that in between the two midrange and final periods of adolescents and with increasing age was not observed.
