Influential Mechanism of Exercise Time on Sport Commitment for Youngsters-The Mediating Effect of Exercise Satisfaction and Social Support

The study combines the concept of exercise satisfaction and social support to analyze the impact and mechanism made by them on sport commitment by testing youngsters through questionnaires and psychological scale, in which the model of sport commitment is the main clue. The finding shows that 1) exercise time, exercise satisfaction, social support and exercise commitment are all positively related to one another. That is, a longer exercise time means a stronger exercise satisfaction and social support, which makes a higher exercise commitment. 2) Exercise time can affect sport commitment both directly and indirectly through exercise satisfaction and social support. The mediating effect of exercise satisfaction and social support on sport commitment has been verified by the hierarchical regression method and the best nature simulation method.
