Caffeine Intake and Additive Effects on Cognition

Can Caffeine Intake Combined With Aerobic Exercise Leads to Cognitive Improvement and Psychomotor Performance in Trained Individuals?

Caffeine is a methylxanthine commonly consumed by the population for their psychostimulant properties, and their intake when in moderate doses seem to produce positive effects on stress, mood and memory. So, understanding that a positive effect of aerobic exercise can be displayed also on cognition, as caffeine, when in proper proportions, the investigators do not know if the joining of the two strategies into a single activity would be able to promote additional effects enhancing cognitive processes related to memory, attention, and motor reaction time.

Determine if 500 mg of caffeine can generate additional effects to 30 minutes of aerobic exercise enhancing cognitive memory tasks (Rey Auditory Verbal Learning Test - RAVLT), attention (sustained attention span; working speed; Percentual of errors by confusion) and simple reaction time (SRT).
