Effects of time of posttest after two durations of exercise on speed and accuracy of addition and subtraction by fit and less-fit women.
18 adult female volunteers, ages 27 to 49 years, were divided into two groups based on their cardiorespiratory fitness to investigate speed and accuracy of addition and subtraction immediately, 5 min., and 15 min. postexercise. A 2 (fitness level) x 3 (exercise duration) x 3 (postexercise performance trials) repeated-measures analysis of variance indicated that, for the fit group, speed of problem solving was significantly faster after both 20-min. and 40-min. exercise sessions across all performance trials; for the less-fit group, speed of addition/subtraction was significantly faster only after the 20-min. exercise session across performance trials. No significant postexercise difference in accuracy was found for either fit or less-fit groups.
