• Resumen

  • Creatine supplementation (CrS) have been used as ergogenic aids for many decades. Although it is useful in several sporting modalities, the use in football is controversial. Evidence has been building up on the benefits that CrS can bring to young football players. The potential interest of CrS for young football players is related to an increased ability to perform high-intensity exercise bouts and metabolism’s improvement. Football is a sport that requires high intensity efforts over and over again during the match. Ostojic (2004) showed that CrS augmented repeated sprint performance and vertical jump performance in young (16±2 years old) soccer players. This data was corroborated by Yanes et al (2017), they found increases peak power output after CrS for Under-20 soccer players. Machado et al (2008) showed a decrease in protein breakdown after extenuate test in football players submitted to CrS.

    Actually, between pre-season, athletes need maintain positive protein net balance and CrS could be help them.

    CrS is safe and many studies do not show health problems induced by supplementations, despite anecdotal data. In other hand, CrS induce corporal mass augment. This side effect could be a problem for some athletes. CrS should not be used indiscriminately, it has utility for some athletes and during some periods of the season.
