Carbohydrate Nutrition and Skill Performance in Soccer

Abstract

In soccer, players must perform a variety of sport-specific skills usually during or immediately after running, often at sprint speed. The quality of the skill performed is likely influenced by the volume of work done in attacking and defending over the duration of the match. Even the most highly skilful players succumb to the impact of fatigue both physical and mental, which may result in underperforming skills at key moments in a match. Fitness is the platform on which skill is performed during team sport. With the onset of fatigue, tired players find it ever more difficult to successfully perform basic skills. Therefore, it is not surprising that teams spend a large proportion of their training time on fitness. While acknowledging the central role of fitness in team sport, the importance of team tactics, underpinned by spatial awareness, must not be neglected. It is well established that a high-carbohydrate diet before a match and, as a supplement during match play, helps delay the onset of fatigue. There is some evidence that players ingesting carbohydrate can maintain sport-relevant skills for the duration of exercise more successfully compared with when ingesting placebo or water. However, most of the assessments of sport-specific skills have been performed in a controlled, non-contested environment. Although these methods may be judged as not ecologically valid, they do rule out the confounding influences of competition on skill performance. The aim of this brief review is to explore whether carbohydrate ingestion, while delaying fatigue during match play, may also help retain sport soccer-specific skill performance.

Dietary Patterns, Gut Microbiota and Sports Performance in Athletes: A Narrative Review

“…Adequate carbohydrate consumption is crucial for athletes. The ingestion of simple carbohydrates before and during exercise (e.g., glucose, fructose, sucrose) can alleviate fatigue, facilitate rehydration and the maintenance of optimal fluid balance, and enhance sports performance [ 124 , 125 , 126 , 127 , 128 ]. For example, lactose may serve as an effective fuel source before, during and after exercise, thereby enhancing sports performance and aiding recovery while also potentially exerting beneficial effects on the gut microbiota, such as increasing Bifidobacteria and Lactobacilli populations [ 81 ].…”

“…Similarly, other scholars believe that soccer players must have excellent cognitive, perceptual abilities, and motion coordination as these factors will determine the effectiveness of the player's actions (Adelina & Anam, 2023;Bojkowski et al, 2022;Ren et al, 2022). In addition to the basic techniques, physical, and nutritional factors, a player's proficiency in mastering football techniques is also known to significantly affect the player's performance (Guntoro et al, 2020;Rollo & Williams, 2023). A player's proficiency is supported by having excellent body condition (Adelina & Anam, 2023;Azmi & Anam, 2023;Modric & Uljevic, 2022).…”
