“Background Artistic Gymnastics training submits athletes to the limit of their bodies and minds through hard training sessions and a competitive schedule that is long and demanding both physically and mentally. Often, athletes train in a state VRT752271 supplier of fatigue and close to their limits. Muscular fatigue is a process that impairs performance, especially with the athlete under caloric restriction, a common feature of this sport modality [1]. Carbohydrate supplementation may be a strategy to counteract this process, since carbohydrate is an important source of energy to the body and to the nervous system, improving the athlete performance [2]. The question that bred this study then was: what is the influence of fatigue on the athlete performance in an exercise

that is highly demanding both, physically and mentally, such as the balance beam? And https://www.selleckchem.com/products/mk-5108-vx-689.html what would be the role of carbohydrate supplementation in this process? Artistic gymnastics involves physical strength, concentration and gracefulness. The athletes are submitted to the limit of their bodies, there is an intense overload which requires Ribonucleotide reductase a lot of effort from the athlete [3, 4]. The balance beam is the more technical apparatus https://www.selleckchem.com/products/poziotinib-hm781-36b.html because it’s a 10 cm wide surface set at 125 cm high and the athletes must perform all movements on

it and without falls [5]. The best result is obtained by the athlete who executes determined movements in its perfect form and don’t fall. Any imperfect movement caused, for instance, by fatigue, can make the athlete fall. Being an individual sports, where all eyes are focused on the athlete at the time of the presentation no errors are accepted, the perfect execution and performance are highly valued [6]. Training is usually exhaustive, both long and of high intensity. Young athletes train an average of 25 hours per week, divided in 5 sessions of 5 hours each [4]. The competition schedule is all year long [7] therefore periodization of the training sessions is not well established. It is mostly based on a large training volume and a very high intensity, keeping the athletes close to their top performance and their limits during all the training period. A gymnast diet is restricted to few calories [8], based on the idea that the lighter the body, less energy is needed to perform the exercises and more gracefully the athlete will do the movements. Also, the risk of injuries decreases, because the impact on the joints will be reduced.
