Personality characteristics associated with aerobic exercise in adult males.
Using an index of aerobic conditioning 23 adult male exercisers and 23 nonexercisers were identified. During individual interviews with each subject basic demographic data were obtained and blood pressure, resting pulse rate, and body fat were measured. All subjects completed Form A of the Sixteen Personality Factor Questionnaire (16PF). Statistically significant differences occurred on six primary factors and four Secondary dimensions of the 16PF. In comparison to the inactive subjects the exercisers, all of whom were joggers or runners, were more reserved, expedient, suspicious, forthright, liberal, and self-sufficient on the primary traits, and were more alert and independent, less discreet, and evidenced lower super-ego strength on the broader secondary patterns. The statistically significant training effects were lower pulse rate and less body fat, but did not include blood pressure.
