Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention
Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the influence of caffeine administered at rest and during fatiguing physical exercise on spatial attention-a cognitive function that is crucial for task-based visually guided behav...
متن کاملantihistamines: psychomotor performance and driving H1 antihistamines: psychomotor performance and driving
As has already been extensively commented in the article on antihistamines and the central nervous system, published in this same issue, all the classical antihistamines and, to a lesser extent, the more recent synthetic compounds are able to exert depressive action upon the central nervous system (CNS), causing drowsiness, lassitude, dizziness, incoordination, and increased reaction time.

متن کاملCaffeine and Exercise Performance
1. Recent, well-controlled studies have established that moderate doses of caffeine ingested 1 h prior to exercise enhance the performance of certain types of endurance exercise in the laboratory. Moderate caffeine doses produce urinary caffeine levels well below the allowable limit, as determined by the International Olympic Committee. The results are specific to well-trained elite or recreati...
متن کاملPolymorphisms of ADORA2A modulate psychomotor vigilance and the effects of caffeine on neurobehavioural performance and sleep EEG after sleep deprivation.
BACKGROUND AND PURPOSE Prolonged wakefulness impairs sustained vigilant attention, measured with the psychomotor vigilance task (PVT), and induces a compensatory increase in sleep intensity in recovery sleep, quantified by slow-wave activity (SWA) in the sleep electroencephalogram (EEG). These effects of sleep deprivation are counteracted by the adenosine receptor antagonist caffeine, implying ...
متن کاملCognitive and psychomotor performance during alcohol hangover.
The consequences of alcohol consumption have risen high on health and social agendas in recent years. Although much work has focused on the physical problems associated with alcohol use, one theme that has emerged in alcohol research has been a focus on the effects of hangovers on functioning. This brief literature review specifically examines recent empirical investigations of the relationship...
