Effects of jogging and cycling programs on physiological and personality variables in aged men.

Abstract Thirty-six men between the ages of 60–79 participated voluntarily in a 14-wk program of walk-jogging (N = 16) or cycling (N = 20). The 2 groups trained 25–50 min/day, 3 day/wk. The subjects were pre- and posttested on a battery of physiological tests including the Astrand bike test, and the Cattell 16 PF. Results indicated a significant (p < .05) increase in predicted max VO2 for both groups and increased flexibility for the joggers. Significant (p < .05) decreases were found in BP and weight for both groups and decreased percent of body fat for the cyclers. After the 14-wk program the cyclers had not changed in any personality factors and the walk-joggers became less surgent and more self-sufficient (p < .05). Comparisons after the 14-wk program between the 2 groups indicated that the cyclists were more tough-minded and surgent than the joggers. No physiological differences between the 2 groups at the conclusion of the program indicated that comparable training effects could be attained by cycli...
