An interventional study of Caffeine Intake and Placebo Intake in Healthy, sponsored by Universidade Federal do Rio de Janeiro. Completed. Open to male participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2016-01-06.

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).
Universidade Federal do Rio de Janeiro is the lead sponsor of 120 studies on the registry; 11 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
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: Caffeine 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.
Other: Placebo 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.
