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.

Conditions

  • Healthy

Interventions

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.
