We applied principal component analysis to the data obtained from twelve kinds of sport-tests (Physicalfitness measurements : side step test, vertical jump, back strength, grip strength, trunk extension, standing trunk flexion, step test. Motor ability measurements : 50-meter run, running broad jump, handball throw, pull-ups, 1500-meter endurance run.) made on students belonging to athletic clubs at Ube Technical College in July, 1980 and obtained four principal components which accounted for 64.6% of the total variance. We investigated the characters of athletic clubs as to each component by means of the analysis above. The results may be summarized as follows : (1) Four principal components may be considered as the following factors. The first principal component・・・Impulse strength (or total kinetic strength). The second principal component・・・Jumping strength. The third principal component・・・Endurance strength. The fourth principal component・・・Muscle power. (2) We transformed individual factor-scores obtained through principal component analysis to new scores ranging from the lowest score 0 to the highest score 10. The new scores explain the characteristics of athletic clubs as regards each component definitely.
