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 [20]. However,
in this study the amount of carbohydrates eaten fell well
below these recommendations, to 33% less than the recommendation
for athletes (REC2) and even to 11% less
than the recommended intake for the group undertaking
only light activity (REC1).
