Efectos del café cafeinado sobre la memoria inmediata y la planificación visomotora en estudiantes universitarios

Abstract

To evaluate the effects of caffeinated coffee (150mg/130 ml) on immediate memory and visuomotor planning in university students, an experimental design pretest-posttest with a control group was used. The sample was constituted by 109 students -54 belonged to the decaffeinated coffee group (control) and 55 to the caffeinated coffee group-. Immediate memory, successes, sequencing, traversing and total mistakes, as well as speed and accuracy were evaluated by a test of visuomotor planning (TESEN). Then, randomly and using the double-blind method, participants drank 130ml of coffee without caffeine/with caffeine (control and experimental group, respectively). After 30 minutes, the same indexes were evaluated with different tests. Data were analyzed by repeated measures ANOVA with an alpha = 0.05. Caffeinated coffee (150mg / 130ml) increased immediate memory and decreased traversing mistakes, showing its light ergogenic effects on students of both sexes
