چکیده

Caffeine is a sports supplement that has been widely used as an ergogenic aid and many articles have confirmed this supplement in improving endurance performance. Caffeine is a plant product and one of the most important and widely used stimulants worldwide. Due to the introduction of caffeine into all tissues of the body, the nervous system and the brain are also affected by caffeine consumption. Caffeine acts as a stimulant and wakes you up, which means that after consuming caffeine, the athlete is more alert and reacts quickly. Consuming caffeine before sports activities reduces pain perception. In one study, people who consumed caffeine experienced less anger during intense exercise. During exercise, the body uses glycogen - stored sugar in the body - to produce energy. But when this source of energy is depleted at the end of a long workout, you feel tired and fatigued. Caffeine slows down the body's depletion of glycogen. This action is done by encouraging the body to use stored fat in the body as a fuel source, which makes the exercise continue for a longer period of time. Due to the rapid depletion of glycogen resources, especially in endurance sports, athletes gain many benefits from caffeine consumption. Activities such as running, cycling, and skiing that last more than an hour and require maintaining peak athletic performance during training, caffeine allows athletes to increase their endurance, accuracy, and speed. Unlike endurance sports, caffeine has no significant effect on strength and power activities such as weightlifting. Caffeine is a popular work-enhancing supplement that has been actively researched since the ۱۹۷۰s. The majority of research has examined the effects of moderate to high caffeine doses (۵–۱۳ mg/kg body mass) on exercise and sport. These caffeine doses have profound effects on the responses to exercise at the whole-body level and are associated with variable results and some undesirable side effects. Low doses of caffeine (< ۳ mg/kg body mass, ~۲۰۰ mg) are also ergogenic in some exercise and sport situations, although this has been less well studied.
