Abstract
This study was attempted to seek for an objective method for diagnosing the sport aptitude of individuals in order to guide into any new courses in sports. The materials used here were the data of 761 excellent athletes among senior high schools in Kyushu district. Thirty-eight test items were selected related to morphological, functional and personality measurements. For analyzing the factors, Thurston's complete centroid method was applied to induce the correlation matrix calculated with these thirty-eight test variables, and then five significant factors were extracted. These five factors deserved to explain 51.6 per cent of total variance and were rotated orthogonally according to the principle of simple structure. These rotated factors are as follows; 1. Morphological factor for growth in weight, circumference, and transverse of chest which are related to static muscular strength, 2. Factor of power and agility, 3. Positive-negative factor of personal traits in dominance, 4. Morphological factor for growth of length, 5. Factor of emotional stability and social adaptability. Thirty-seven sports were able to be classified into some common types with these factors so as to prepare the tables of sport types. These classified tables of sport types seemed to be useful for the guidance in sport aptitude of the individuals.
