Sample text

Caffeine use has been associated with increased alertness and enhanced physical performance, and as a countermeasure to the effects of sleep deprivation. Extensive research has been done on each of these effects of caffeine. A brief summary of research findings on the efficacy of caffeine is presented here. PHYSICAL PERFORMANCE Caffeine has been proposed as an ergogenic aid in physical performance. Its use is associated with a reproducible increase in endurance time in activities of moderate intensity and long duration.

NOTE: It is important to emphasize that the responses to the questions and recommendations in this report are specific to military operations and are not necessarily applicable to the needs of the civilian population. In particular, it is recognized that mental alertness and vigilance in situations of sleep deprivation may be necessary during military operations in order to achieve mission objectives. In the civilian environment, taking large doses of caffeine to offset lack of sleep in situations where public safety and health could potentially be compromised, such as in the operation of aircraft, motor vehicles, heavy equipment, delicate life-saving procedures, and the like, is not justified.

Recommendations Definitive research is needed regarding the combined effects of caffeine and carbohydrate on performance since data currently available are inconclusive. If a food bar or some other solid food matrix is used, the rapidity and extent of caffeine absorption and action must be evaluated. Under certain circumstances, such as heat stress or desert operations, chewing gums may offer practical operational advantages over a food/energy bar. Thus, two delivery vehicles should be considered.
