title: Caffeine and Performance.
abstract: The role of caffeine in enhancing performance has been studied for years, and there is no doubt that caffeine can be performance enhancing. Also, a wealth of information allows for an interesting distinction between physical and cognitive performance. Most adults in America consume moderate doses of caffeine in various forms on a daily basis as caffeine is typically found in coffee, tea, soft drinks, dietary supplements, energy drinks, energy shots, and chocolate, as well as over-the-counter pills and gums. Although caffeine is readily available and widely consumed, when using it to enhance performance, a few factors should be considered. The authors discuss caffeine use among Servicemembers, its properties and effects on physical and cognitive performance, how to use it to optimize performance, and, finally, some of safety and regulatory considerations. The bottom line is that all individuals do not respond the same way to caffeine and their response depends on how the body uses and breaks down caffeine. Thus, as a user, you should monitor your own responses and performance changes when using caffeine based on the general recommendations provided.
