Ergogenic substances influence the body's ability to produce energy, in particular they impact sports performance, the perception of fatigue and the speed of recovery.
Through a correct supplementary strategy, it is possible to benefit from the intake of these aids.
In the Runner, the first factors impacting on performance are certainly training and balanced nutrition; however some substances can be considered to improve potency and to reduce the perception of fatigue.
Caffeine, for example, is one of the most studied supplements; it is a stimulant that exerts direct effects on the cardiovascular system, increasing the heart rate, and on the central nervous system, stimulating mental and mnemonic abilities.
Numerous scientific studies confirm the effectiveness of this substance in improving performance in endurance sports, at high intensity and in team sports, with discontinuous shots.
In the Runner it can help improving reaction times, wakefulness, stimulating the adrenergic system, positive effects achieving a better psychophysical performance.
Thanks to its rapid ability to cross biological membranes, Caffeine can be taken during the race to overcome moments of "difficulty", and maximum fatigue, through gels, in association with a correct intake of carbohydrates and sugars, such as maltodextrins , for the gradual release of energy.
Another substance that can be considered by the Runner is Carnitine, because it is often lacking (especially in those who train for a marathon), and because it is useful for energy purposes.
This substance is synthesized by the body, is present in skeletal muscles, heart muscle, kidneys and liver, and is found mainly in foods of animal origin. However, it can also be taken as a food supplement, since, carrying out its role in the oxidation process of fatty acids, resulting in the production of energy, it leads to a better use of fat energy, favoring glycogen savings, and reducing the risk of muscle damage.
