The recommended daily consumption of carbohydrates to maintain muscle glycogen stores over several days of intense training is between 500 g and 600 g, that is, between 60% and 70% of total energy intake
There is widespread evidence to suggest that an increase in carbohydrate intake can improve performance in various kinds of sports activity, including refereeing, which requires intermittent running at various intensities.
The referees and linesmen in the sample had a greater consumption of proteins than the recommendation for adults, at 125.8 g/day. This may be of benefit to their performance, as the demands in relation to stamina and strength made
upon them by their activity may be favorably affected by a protein intake that is above recommendations.
This level of consumption may improve strength and provide amino acids to serve as a substrate for any increase
in amino acid oxidation that may occur during training and games
