Caffeine d Not just a stimulant

  title={Caffeine d Not just a stimulant},
  author={Michael J. Glade},
Objective: The beneficial effects of human caffeine consumption deserve clarification. Methods: A detailed literature review was conducted and summarized. Results: A large body of scientific evidence describes the beneficial effects of human caffeine consumption on a number of physiologic systems. Conclusion: The consumption of moderate amounts of caffeine 1) increases energy availability, 2) increases daily energy expenditure, 3) decreases fatigue, 4) decreases the sense of effort associated…

Effects of repeated doses of caffeine on mood and performance of alert and fatigued volunteers

The results showed that caffeine led to a more positive mood and improved performance on a number of tasks, evidence against the argument that behavioural changes due to caffeine are merely the reversal of negative effects of a long period of caffeine abstinence.

Cognitive and psychomotor performance, mood, and pressor effects of caffeine after 4, 6 and 8 h caffeine abstinence

The results show that, apart from caffeine consumption soon after waking, the daily pattern of caffeine intake of many typical caffeine consumers is not well explained by the short-term psychostimulant effects of caffeine.

Caffeine effects on recovery sleep following 27 h total sleep deprivation.

Caffeine exerts mild deleterious dose-response effects on recovery sleep following total sleep deprivation, primarily early in the sleep period, with potential recovery from these effects after sufficient sleep as suggested by lack of post-recovery sleep performance deficits.

Caffeine improves physical and cognitive performance during exhaustive exercise.

Caffeine in a performance bar can significantly improve endurance performance and complex cognitive ability during and after exercise and may be salient for sports performance in which concentration plays a major role.

A naturalistic investigation of the effects of day-long consumption of tea, coffee and water on alertness, sleep onset and sleep quality

It is demonstrated that day-long tea consumption produces similar alerting effects to coffee, despite lower caffeine levels, but is less likely to disrupt sleep, and ingestion of caffeinated beverages may maintain aspects of cognitive and psychomotor performance throughout the day and evening.

The effects of low doses of caffeine on human performance and mood

Single doses of caffeine gave to 20 healthy male subjects assessed various aspects of performance and self-reported mood states, as well as plasma caffeine concentration, and found that as little as 32 mg significantly improved auditory vigilance and visual reaction time.

The Effects of Caffeine and Aspirin on Mood and Performance

It is demonstrated that the addition of caffeine to aspirin, in a dose commonly employed in over-the-counter drugs, has significant beneficial consequences with respect to mood and performance.

Effects of caffeine, sleep loss, and stress on cognitive performance and mood during U.S. Navy SEAL training

Even in the most adverse circumstances, moderate doses of caffeine can improve cognitive function, including vigilance, learning, memory, and mood state, and a dose of 200 mg appears to be optimal under such conditions.

Influence of caffeine on perception of effort, metabolism and exercise performance following a high-fat meal

Perception of effort was reduced during exercise after caffeine ingestion and this may be attributed to the direct stimulatory effect of caffeine on the central nervous system, however, this caffeine-induced reduction in effort perception did not improve exercise performance.

Restoration of risk-propensity during sleep deprivation: caffeine, dextroamphetamine, and modafinil.

Stimulant medications, particularly dextroamphetamine, sustained risk-related attitudes and behavior during continuous wakefulness and restored risk-taking propensity and risky behavior to baseline levels, compared with previous reports of the effects of sleep deprivation.
