The theme of the present study, based on Self Determination Theory (DECI, RYAN, 2000), is the motivation for practice of regular physical activities (RPA) in adolescents aged 12 to 15 years classified in different Body Mass Index (BMI) levels (normal weight, overweight and obesity). Considering the high levels of physical inactivity and excess weight found in adolescents and how dangerous they are to health, is important to know the level of Intrinsic Motivation (IM) for physical activities among these individuals. The goal of this study was to analyze the level of Intrinsic Motivation for the practice of RPA in adolescent students and its relation to their BMI. More specifically, describe BMI, sex, and RPA practices outside the school environment. IM was described according to these variables and the relations between IM and these variables were tested whit SPSS 20.0. To measure IM we used the Inventário de Autodeterminação de Praticantes de Atividades Físicas e Esportivas – (BALBINOTTI, 2008), BMI measures and a questionnaire for the control variables. The study was applied in 267 students (116 boys and 151 girls) aged between 12 and 15 years, studying in middle schools in the cities of Canoas and Sapucaia/RS. Result showed the prevalence of excess weight to be high (19,9% overweight and 11,2% obesity). For both sexes, the distribution of BMI was similar. The prevalence of physical inactivity outside school is of 32,2% in the total sample. There are no differences in this variable when comparing BMI groups, but when comparing sexes, girls where significantly more inactive then boys. The levels of IM where higher in the normal weight group ( χ =94,36), followed by the obese ( χ =92,03) and overweight groups ( χ =87,72), and the statistical difference was found only between normal weight and overweight groups. Boys ( χ =97,41) where more intrinsically motivated than girls. Adolescents who practiced physical activities ( χ =97,06) regularly in leisure time where more intrinsically motivated then those who didn’t ( χ =83,79). The results corroborate recent studies in the field, with the exception of the high Intrinsic Motivation found in the obese group, and the similarity in RPA practice outside school between the BMI groups. These findings are relevant, especially for Physical Educators working among adolescents.
