This study has been approved by the Hamilton Integrated Research Ethics Board.

The Department of Kinesiology is recruiting individuals between 18 to 30 years of age with a formal diagnosis of ADHD to take part in an exercise psychology study. Importantly, if you are taking ADHD medications we will ask that you withhold from using your medication at least 24 hours before the start of the remote data collection session.

This study will be conducted remotely through Zoom and tasks will be administered online. The study will begin with the completion of a number of questionnaires and cognitive tasks of executive functions. This will be followed by the 6 minute walk test, which will be administered through the 6WT App which can be downloaded for free in the App Store or Google Play. This is an exercise test that requires the individual to walk as far as possible in 6 minutes without jogging or running. This test should be completed outside on a relatively flat or gently sloping and uninterrupted path. The full duration of the study should take approximately 2.5 hours to complete
