The Role of the Time of Day in the Effects of Exercise on Memory in Heathy Young Adults

Eligible participants will come into the lab on day 1 and 3 at the same time of day (either morning at 7-10am or afternoon at 3-5pm). They will be then randomly assigned for a rest or an exercise session prior to the memory test. For the rest condition, they will be required to sit and relax while watching Planet Earth for 30 minutes on a cycle ergometer. During the exercise session, they will complete a moderate-intensity cardiovascular exercise for 20 minutes following a 5-min warm-up and followed by a 5-min cool-down on a cycle ergometer. They will start the memory test immediately after the rest/exercise session.
