Time Estimation Performance Before, During, and Following Physical Activity


Vercruyssen, M., Hancock, P.A., & Mihaly, T. (1989). Time estimation performance before, during, and following physical activity. Journal of Human Ergology, 18, 169-179.

An experiment is reported which evaluated performance on a 10-sec unfilled time interval estimation task before, during, and after physical work on a cycle ergometer at relative intensities of 30 and 60% VO2max. Results from eleven healthy male subjects revealed a significant increase in time estimation variability and a decrease in the mean estimated time intervals during exercise compared to non-exercise phases. These findings are part of a growing body of evidence which indicates that exercise and its severity has a substantive impact on perceptual and cognitive performance, particularly the ability to synchronize and anticipate the timing of events.
