Problem Statement: “Creativity, specific to human beings, is of a vital importance in the evolution of culture and society, was considered for a long period of time, a quality or a characteristic which, mysteriously, was given to a person” (Horst H. S., 2000, p. 99). Today, as a result of research undertaken, this capacity is recognized as a “personality factor existing in any one of us” (Horst H. S., 2000, p. 99) in a smaller or bigger proportion, according of one's stimulation or practice upon it. Evaluation of creativity can be done through several tests. These tests can determine: the wealth of the lexical fund, the fluidity of lexical association, divergent thinking, visual creativity, etc.). In the present study, in order to demonstrate the hypothesis, we have chosen to evaluate the richness of the lexical fund and fluidity of lexical association, each addressing other dimension of the creative power of individuals and how this creative dimension is influenced by the participation or lack of it at physical activities within physical education lessons. Purpose of Study: This research has started from the hypothesis according to which people who constantly participate at physical activities have a much developed creative capacity, as compared to those who refuse to make effort and have medical exempts. This research has been realised on a group of students involved in the educational process from the Petroleum-Gas University in Ploiesti. Research Methods: Bibliographic study method; observation method; investigation method (conversation, questionnaire, scale Fl, scale Al, etc.); pedagogical experiment method; statistical-mathematic method; graphical method. Findings and Results: Creativity is the recombination of concepts that existed or still exist in the human mind, hidden in the subconscious and which could be activated as needed. Creativity seems to be more developed in people who regularly participate in physical activities. Conclusions and Recommendations: It is widely known that innovation can not exist outside creativity. On a market that can not be satisfied, creativity and intelligence are very rare qualities, sought in all areas of activity, being very well paid. For this reason we believe that the proposed theme is very new in the research field, that it opens new research perspectives and the statement that physical activities stimulate creativity, values it and represent a manner of lifelong training-learning, thus confirming the hypothesis. As a consequence, we recommend the existence of physical education lessons even since kindergarten.
