Abstract: The category of “physical strength” originated from people’s procedural dynamic description about doing pro-ducing and living practice by holding a production tool called “Lei” (an ancient plough) by hand. In people’s ideology and actual action, “physical strength” has gone through such a negation of negation process of transition as being valued – be-ing not valued – being valued. Currently “physical strength” is at a stage of being valued again. The essence of the cate-gory of “physical strength” is understood as follows: 1) it is a category existing relatively with “intelligence” (sedentary); 2) it has a targeted object – oneself or the outside world, and the targeted object varies in different periods; 3) it describes, explains and predicts the external dynamic performance (i.e. action) of the body as it moves; 4) it is a category of cross re-search of such disciplines as military science, social medicine, architecture and health science; 5) it has two research direc-tions, one of which is outward, the other is inward. Factors that affect the transition of the category of “physical strength” include political, military, cultural and technological factors, especially technological factors.
