• Trial end date: 2018-08-01
• Target enrollment: 0
• Participant gender: All

Summary

The effects of moderate intensity aerobic exercise and caffeine ingestion on cognition (more specifically working memory) in non-caffeine drinker and caffeine drinkers will be examined. The non-caffeine drinkers will be recruited for two visits, whereas, the caffeine drinkers will be recruited for three visits. The study involves a baseline assessment of cognition and examines the effects of exercise and caffeine. Finally the caffeine group will consist of a baseline and intervention assessment when deprived of caffeine (overnight abstinence). The exercise intervention is to complete 20-minutes of moderate intensity exercise (brisk walk) while the caffeine condition is to consume 1.2 mg/kg of caffeine. Immediately following both intervention the n-back assessment will be conducted.
