Effects of Caffeine on Physical and Cognitive Performance: A Brief Review
Journal Title: Scholarly Journal of Psychology and Behavioral Sciences - Year 2018, Vol 1, Issue 3
Abstract
Caffeine is one of the most extensively studied and widely used ergogenic aid capable of improving many aspects of sport performance and cognitive abilities [1-12]. Some of the acute effects of caffeine supplementation are increases anaerobic power output and performance, increased muscular strength, endurance, and power, improvements to aerobic endurance, reduced fatigue, decreased RPE and pain, increased voluntary workload, and increased alertness [1-8]. Chronic caffeine consumption has also been shown to have a positive effect on long term memory, locomotor improvements, and overall mood state [9-11]. Some of the positive effects of athletic performance attributed to caffeine ingestion can be explained by its ability to moderate insulin sensitivity, increase plasma free fatty acids (FFAs), and increase plasma epinephrine [12]. These results demonstrated that caffeine consumption can allow more glucose and FFAs to be available in the blood for immediate energy. Furthermore, caffeine has been shown to increase calcium release from the sarcoplasmic reticulum of muscle fibers, which could result in increased actinmyosin binding and therefore increased force production [12]. Some of the acute physical effects of caffeine supplementation are increases anaerobic power output and performance, increased muscular strength, endurance and power, improvements to aerobic endurance, and reduced fatigue [1,3-6,8]. Additionally, acute caffeine consumption also enhances cognitive function during physical tasks as demonstrated through a reduction in self-reported rate of perceived exertion (RPE) and pain perception, increasing voluntary choice of work load, and increasing alertness [2,7,9].
