title: Effects of time of posttest after two durations of exercise on speed and accuracy of addition and subtraction by fit and less-fit women.
abstract: 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.
