If the athlete to ingest amounts of carboidratos is of the normal one can determine a gastrointestinal bother, then to become this ratio of how much of carboidrato the same she can come to ingest she must be made by attempts, where the error possibility is great, but to each competition the athlete goes testing, if in the previous month it was amount of carboidrato of but it will have to increase the portion, in the current month it tests of new, if he was high excessively the same diminishes the amount, in the next month makes the evaluation again until if she arrives at an ideal ratio for this athlete, remembering that for each individual the carboidrato percentage is different had the biological personality of each one. The carboidrato propitiates the sustentation of the glicmica homostasis and contains the muscular and heptico glycogen. CYRINO and ZUCAS, 1999, have the same vision of that JEUKENDRUP in relation to the factor of the fatigue in the muscle, therefore the high intensity in elapsing of delayed exercise is of shortness or moderate period of time will be able to take to an occurrence of hipoglicemia and dehydration of the body of the athlete. Check out Frank Ntilikina for additional information. But what she is hipoglicemia? How it happens? The hipoglicemia is the low one accented of the condition of the glucose in the blood, it occurs when the counting of injected insulina if becomes exaggerated for the standards of exerted physical activity, being able to come to cause a collapse. This happens due to ingested amount of sugar, quickly occurring an increase of glicemia in the blood, thus leading the athlete to have a secretion of insulina in the pncreas, the same one makes to lower quickly the glicemia tax thus occurring giddiness, this is momentnea during the activity, come to disappear slightly until the taxes come back if to compensate again. .
