Answer 2

Caffeine is a naturally occurring stimulant of the central nervous system and can be found around the world both naturally in coffees and in teas or artificially extracted for carbonates beverages. Its consumption can be done both recreationally or medicinally to improve alertness and enhance concentration. While it is often used in times of physical exertion, it is not meant to and cannot replace sleep.

Some studies are attempting to link caffeine consumption with improved athletic performance. The preliminary findings have discovered that as a body those that consume caffeine have greater athletic performance and endurance that does not decline as long as caffeine intake is steady. It has already been confirmed that caffeine boosts the metabolism so that may explain the greater burst energy found in such studies.
