| Abstract: | 10 male, middle-distance runners selected for their potential or actual success in running 1500 metres were subjected to laboratory tests of VO2 max and run time at 85% VO2 max. Using the Eysenck Personality Inventory (Eysenck, 1962), data were collected from the runners from which they were given a score on the Extraversion/Introversion dimension of personality. Pearson product-moment correlations were computed between 1500 m. run times and VO2 max, 85% utilization of VO2 max, and Extraversion scores. The highest correlation was between Extraversion and the 1500-m. run (r = .75). The multiple correlation between times for the 1500-m. run and Extraversion with VO2 max was .77. The results support the value of building comprehensive profiles for the athlete which include not only physiological and anatomical variables but behavioral measures as well. |
