The effects of two stress management programs on the cardiorespiratory efficiency of eight male cross-country runners were investigated. Oxygen consumption and heart rate data were monitored on a maximal oxygen consumption tradmill run. A week later each subject completed a 20-min submaximal run (at a constant workload approximating 50% of each subject's maximal oxygen consumption run). Based on these scores, subjects were divided into three groups: control, stress innoculation training, and stress management training. Subjects in both training groups completed a mental training program including EMG relaxation training, cognitive coping strategies, and one type of imagery training. Results of the 20-min post submaximal run indicated significant differences in cardiorespiratory efficiency between both training groups and the control group. No differences emerged between the training groups.
