Data for performance on an associative memory test decreases 8 hours after cardiovascular exercise
Summary: Raw data is presented of participants’ heart rates during 20 minutes of treadmill running or 20 minutes of solving a Sudoku puzzle. Furthermore, data sets are included of participant’s scores on a Paired Associate Learning [PAL] test at baseline “pre” and after a delay of either 2, 5, or 8 hours “post”. Each participants heart rate and their perceived level of exertion using the Borg Scale is also included. General Procedure Participants took part in two experimental sessions, both on the same day. The first session started for all participants between 8:30–9:30 am and lasted approximately 50 minutes. In this session participants first performed a baseline paired associates learning [PAL] test and then, within approximately 1 minute, the exercise group ran on a treadmill for 20 minutes and the control group played Sudoku puzzles for 20 minutes (from www.websudoku.com). Participants then returned for their second session after a self-selected a delay of 2 (exercise group n=17, control group n=18), 5 (exercise group n=19, control group n=18) or 8 (exercise group n=16, control group n=18) hours (see Fig 1). During the second session, participants completed a second PAL test, using entirely different words than the baseline test. Using this experimental design, encoding and retrieval occurred in close proximity to each other (within approximately 2 minutes), and thus both were completed before the exercise or control task for the baseline PAL test, and at variable delays after the exercise or control task for the second PAL test.
