INTRODUCTION: Anaerobic performance refers to high intensity, short duration exercise performance focusing on speed and power. These are short duration exercises with a high intensity, lasting from three seconds to a maximum of two minutes. The predominate systems within the body working during these performances are the adenosine triphosphate and phosphocreatine (ATP-PC) systems which utilizes stores in the muscle and anaerobic glycolysis which generates ATP and leads to the metabolic byproduct, lactic acid. Caffeine is a central nervous system (CNS) stimulant. This drug increases the metabolism of fatty acids, and in turn spares muscle glycogen to enhance performance. Glycogen is the stored carbohydrate located within muscle tissue, and to a lesser degree, the liver. Caffeine can also reduce the perception of fatigue within individuals. The neural stimulus and motor unit firing rates stimulated by caffeine can also enhance strength. For the purposes of this study, both sparing of muscle glycogen and reduced CNS fatigue may contribute to increased anaerobic performance.
