Timing and method of increased carbohydrate intake to cope with heavy training, competition and recovery
Abstract
Based upon the fact that fatigue during intense prolonged exercise is commonly due to depletion of muscle and liver glycogen which limits both training and competitive performance, this paper has proposed extraordinary dietary practices which generally advocate high carbohydrate intake at all times before, during and after exercise. The simple goal is to have as much carbohydrate in the body as possible during the latter stages of prolonged intense exercise when the ability for intense exercise usually becomes limiting to performance. This theory is put into practice by recommending that carbohydrate intake after exhaustive exercise should average 50 g per 2 h of mostly moderate and high glycaemic carbohydrate foods. The aim should be to ingest a total of about 600 g in 24 h. Carbohydrate intake should not be avoided during the 4 h period before exercise and in fact it is best to eat at least 200 g during this time. When possible, carbohydrate should be ingested during exercise, generally in the form of solutions containing glucose/sucrose/maltodextrins, at a rate of 30-60 g h-1. Emphasis has been placed upon eating the optimal amount and best type of carbohydrate at the proper times because these practices demand a large amount of food. When diet is not carefully planned according to these guidelines, endurance athletes tend to consume too little carbohydrate because they become satiated with high fat in their diet and they go through periods in the day when recovery of glycogen stores is suboptimal and thus precious time is wasted.

“Nevertheless, with a mean glycogen storage rate of 5-6 mmol/kg w.w./h, 20-24 h of recovery are normally required for normalization of muscle glycogen levels following extreme exercise depletion (30).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
