The youth soccer generally players undergo a rapid growth and
maturational changes with physiological, anatomical, and biological
changes [1] and over the years, they can optimize physiological
demands results in their athletic performance improve. Something
was proved by a research that evaluated youth-soccer players
during seven years of follow-up, it was observed that in youth
soccer, in which the sprint distance and number of sprints increased
by ~35%, whereas the number of high-intensity actions increased
by ~50% [2]. In this way, there is the importance of a specific
food intake for this sports category, because there are findings
displaying mean energy deficits almost 900 kcal. day-1 in highperformance
youth soccer players caloric intake [3], something
that can influence the athlete’s performance, impair the game
level, and even influence the injury risk. Before speculating about
the calories to be ingested, it is interesting to know the number of
calories spent by high-performance youth soccer players, where
the mean values without standard deviation of the total energy
expenditure measured by indirect calorimetry of high-performance
youth soccer players from the English Premier League were 2859
kcal. day-1(68 kcal. kg-1. day-1), 3029 kcal. day-1 (50 kcal. kg-1. day-
1) and 3586 kcal. day-1 (44 kcal. kg-1. day-1) for U12, U15, and U18,
respectively [4].
When thinking about the soccer players basic categories, the
question can be raised: “Can the macronutrient recommendation
vary with the athlete’s age?” Well, it seems not, the recommendations
will be based on grams per kilogram of body weight per day, for
macronutrients, and total calories, for daily energy consumption,
how proven research that concluded daily energy intake over the
4-day period was similar between adults’ elite soccer players (2988
± 583 kcal. day-1) and youth elite soccer players (2938 ± 465 kcal.
day-1), proving this way that despite the ages being different, young
elite soccer players may have an energy intake around 3000 kcal.
day-1 [5].
Another recent study evaluated youth soccer players from the
base categories, in which caloric intake and carbohydrate intake
were evaluated, found an approximate mean of 1900 Kcal and
255 g [6]. Other recent find suggests the food consumption by
the carbohydrates should be between 5 and 7 g. kg-1. day-1 CHO,
irrespective of age or nationality into high performance youth
soccer players [7]. And, about another consumptions, involving
proteins and lipids too, come a clinical trial study involving 42
youth soccer players with a mean age of 16.7 ± 1.5 years managed to
collect data on food consumption of these athletes for total calories,
carbohydrates, proteins, and fats, with findings on average of 3477
Kcal. day-1, 6.4 g. kg-1. d-1, 1.8g. kg-1. d-1 and 1.8 g. kg-1. d-1, respectively
[8]. In Brazil, youth games usually take place on Saturdays or
Sundays in the morning [9], so the author summarized a (Figure 1)
with the main dietary recommendations for a soccer player during
a game day.

soccer players.
