From culturological points of view ,on the one hand, PE is a kind of body-cultural activity with little ideology, while moral education is strongly ideological. One is physical, the other is metaphysical. They form a sharp contrast; on the other hand, unlike arts which shows feelings and ideas a priori, PE mainly demonstrates feeling and ideas I concrete activities.

目前看来，国际上存在着优秀运动员文化知识欠缺和智力水平较高的反差、教练员中具有高水平运动经历者多和掌握精密体育科学者少的矛盾；这种反差和矛盾是体育自身不可克服的哲学矛盾所致，还是体育管理体制和运动机制不合理所致，值得深思。
