Introduction: Physical activity is one of the most important health behaviors. The aim of this study was to determine the factors related to physical activity based on the “BASENF Model” in Kerman University of Medical Sciences in 2016.

Methods: In this descriptive-correlational study, 480 male and female students were selected through stratified sampling. To collect data, the “International Physical Activity Questionnaire” and a questionnaire based on the “BASNEF Model” were used. Content validity and reliability by Cronbach's alpha was determined by five experts. Data was analyzed by SPSS 20.

Results: In this study, physical activity levels at 0.56%, 28.1% and 15.2% were considered as low, moderate and high, respectively. There was a correlation in age, income and education, with physical activity. The most important predictors of physical activity were enabling factors and behavioral intention.

Conclusions: Enabling factors and behavioral intention were determined as the two most important predictors of the model. Due to low physical activity in students, planning physical activity sessions are suggested.
