Psychologic effects of cardiovascular conditioning: a controlled experiment

Abstract

Although there have been numerous studies documenting a relationship between physical fitness and psychologic functioning, few have employed the type of experimental design that would allow conclusions to be drawn regarding cause and effect. In the present study, college students were randomly assigned to a cardiovascular conditioning program or to a control program designed to give the appearance of physical training while minimizing cardiovascular benefits. Both groups were tested for cardiovascular fitness as well as on a number of self-rating scales before and after the 6-week program. The cardiovascular group demonstrated a significantly greater improvement in cardiovascular fitness than the control group and also tended to show a greater reduction in anxiety and greater increase in measures of general psychologic well-being.
