Exercise Intensity And Fractionated Response Time, Danielle R. Martineau, Ronald V. Croce, Wayne Smith

Data Catalog

We investigated the role of three intensities of aerobic exercise (Low Intensity [LI], Moderate Intensity [MI], High Intensity [HI]) on information processing and cognition (IPC) by analyzing response time (RPT) and its fractionated components (1) reaction time (RT, interval between stimulus onset and muscle activation, and (2) movement time (MT, time interval between muscle activation and completion of the required motor response). Twenty-seven participants (16, male; 11, female) between the ages of 18-25 (mean age = 21.9 years) took part in 1-choice, 5-choice, and dual-task (DT, counting backwards by 3) conditions prior to and 1-min and 20-min postexercise.
