In this article the relationships between three different types of intrinsic motivation and students' intention to be physically active after school graduation were examined. The participants were 400 school children aged 14-18 years. The modified version of SMS was used to measure the three different types of intrinsic motivation. The intention scale as a measurement of physical education outcome to be physically active was specially designed for this study. The data were analysed by means of structural equation modelling. The goodness of fit indexes of confirmatory factor model for three types of intrinsic motivation provided the evidence of existing different dimensions of intrinsic motivation among students in the physical education setting. The results of this study indicated that the intrinsic motivation to experience stimulation was the strongest predictor of intention to be physical active after school graduation, beyond the intrinsic motivation to accomplish.
