Summary

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.

Detailed description

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).

Conditions

• Healthy

Interventions

Type	Name	Description
OTHER	Caffeine Intake	The experimental group ingest 500 mg of caffeine before (60 min) aerobic exercise (procedure double blind), and perform a battery of neuropsychological and psychomotor tests. 1 min and 30 min after the exercise the subjects perform a new battery of neuropsychological and psychomotor tests.
OTHER	Placebo Intake	The control group ingest 500 mg of placebo before (60 min) aerobic exercise (procedure double blind), and perform a battery of neuropsychological and psychomotor tests. 1 min and 30 min after the exercise the subjects perform a new battery of neuropsychological and psychomotor tests.
