A pilot study (N=100 students) was conducted to test the reliability and validity of the measurement. A comprehensive model was developed, based on an extensive literature review, and empirically tested using by using sport management student (N= 395) of National Taiwan University of Physical Education and Sport (NTUPES), Ton Duc Thang University (TDTU) and Hochiminh University of Sport (HUS) as respondent.
　　All the hypotheses of this study were supported. The results indicate that individuals with high level of personality ( emotional stability, extraversion, openness to experience, agreeable ness and conscientiousness) will have positive influence on basic psychological needs and exercise motivation then impact on exercise behavior. It also suggested that extraversion, openness to experience and conscientiousness could be the predictors of basic psychological needs, autonomous motivations (identified regulation and intrinsic motivation) and exercise participation.
