The motor action is the most important object of study in the sports sciences, where most of the times is analyzed in terms of positivism. It is found that such an analysis is generally constructive; however on the general-conceptual level is insufficient. The philosophical-anthropological approach, where the motor action is researched as a human act performed on a large scale is much more appropriate. This approach allows studying the basic particularities of the motor action, where in the sports sciences, usually remain out of the way of researcher attention: the spontaneity of the motor activity, the ethical character of the space where the motor action is performed, etc. In the article, the opinion on the necessity and possibility of the modernization of sports sciences is argued from philosophical-anthropological approach point of view.
