ABSTRACT

RICHARD H. COX, TOM R. THOMAS, AND JOSEPH E. DAVIS. Positive And Negative Affect Associated With An Acute Bout Of Aerobic Exercise. JEPonline. 2001;4(4):13-20. The purpose of this investigation was to test the hypotheses that (a) positive and negative affect would fluctuate as a function of exercise intensity and mode of exercise, and that (b) the effects of exercise on positive and negative affect would be retained for up to 60 min following an acute bout of exercise. Male participants (N=24) were randomly assigned and habituated to exercise on either a treadmill, or a stationary stepper. Participants completed 30 min of exercise on their assigned apparatus at an intensity of either 50% or 75% predicted VO2max. Psychological affect was assessed using the Subjective Exercise Experiences Scale (SEES) prior to exercise, and at 5, 30, and 60 min after. An intensity by mode by time (2x2x4) MANOVA resulted in a significant main effect for time (p=0.005), and borderline significant main effect for mode (p=0.056). From a univariate perspective a significant difference was noted between the stepper and the treadmill for perceived fatigue (p ................
