Nutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football’s physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.
It is crucial to ensure an adequate nutritional support for young soccer players under high physical stress situations, including match days and high training load days. Therefore, this study aimed to investigate the dietary intake of young male soccer players from a Portuguese first league soccer club, both on match day and on the highest training load day of the week. All players recorded their ingestion at these moments for 3 consecutive weeks, by completing a food diary and making a photographic record. On match day, the intake of carbohydrates (5.2 ± 0.6 g.kg -1 . d -1 ), proteins (2.1 ± 0.2 g.kg -1 . d -1 ), and fats (1.0 ± 0.2 g.kg -1 . d -1 ) represented 55.1 ± 5.0 %, 22.3 ± 1.52 %, and 23.9 ± 5.1%, respectively, of the average daily energy intake. Regarding the highest training load day, the intake of carbohydrates (5.2 ± 0.9 g.kg -1 . d -1 ), proteins (2.0 ± 0.3 g.kg -1 . d -1 ), and fats (1.0 ± 0.3 g.kg -1 . d -1 ) represented 54.8 ± 5.3 %, 21.8 ± 1.8 %, and 24.6 ± 4.6 %, respectively. There were no statistically significant differences between intakes during match day and on the highest training load day, for all the variables analyzed, except for percentage of fat intake (Energy intake p = 0.873; Protein p = 0.335; Carbohydrates p = 0.814; Fat p=0,000). The results obtained are in line with previous research and reveal that energy and carbohydrate intake are below the recommendations for this population.
