摘要：AbstractThe objective of our study is to find the personality factors that determine success in tennis. The study consists in two parts: a) a study on a group of 33 athletes aged 10 to 12 years (average=11.5 and SD=.55); b) a study of 67 athletes aged 13 to 18 years (average=15.39 and SD=1.63). To find personality factors involved in tennis according to the age of athletes, in the first study it was used the HSPQ personality test for children, and in the second study the measurement was conducted using NEO-PIR test, using the procedure for computing all sizes and facets of the questionnaire. All these questionnaire results were compared with the position and the accumulated points in the national ranking. Our findings indicate that the explanatory factor of performance at the level of juniors and children tennis players is the level of conscientiousness.
