College students’ health-hazardous behavior of physical exercise absence is rather common，especially among the girls. The main reasons for this phenomenon lie in busy school schedule，lack of free time，no interests，no professional guide，lack of sports venues and facilities，no organizers or companions，etc. The views of pre-existing analyses are just descriptive analysis on the lateral surface while lack deep analysis of the psychological，physical and social factors from the perspectives of sociology，psychology and kinematics. Aimed at these problems and their reasons，many corresponding measures and suggestions have been proposed by scholars in this field.
