The general dietary needs of the young soccer player appear to be similar to those of the adult soccer player. There are, however, several age- and maturation-related differences. Compared with adults, children's daily recommended protein intake (per kg body mass) is higher; during exercise, children's muscles rely more on fat than on carbohydrates, but it is not clear whether young soccer players need higher dietary fat; calculated per kg body mass, the metabolic demands of walking and running are considerably higher in children; and during dehydration, children's core temperature rises faster, which calls for stricter enforcement of hydration. To increase fluid palatability, drinks should be flavoured, according to the child's individual preference. The efficacy and safety of 'carbohydrate loading' have not been studied in children.

The main aim of the present study was to uncover multivariate relationships between sleep quantity and quality using principal component analysis (PCA) in professional female soccer players. A second aim was to examine the extent to which objective sleep quantity and quality variables can discriminate between perceived sleep. Ten objective sleep variables from the multisensory sleep-tracker were analyzed.

Sleep hygiene can be defined as practicing habits that facilitate sleep; poor sleep hygiene is common among elite athletes, and improving this can be one way to enhance sleep indices. Given the large inter-individual variability of sleep, there is a need for further investigation into individualised sleep hygiene for elite female athletes, with consideration for the practical application of the method. Using a self-controlled time series design with repeated measures, n = 16 professional female footballers completed a 9-week study during mid-season.

Purpose: To compare football players who have undergone one anterior cruciate ligament (ACL) reconstruction (ACLR) with those who have undergone a subsequent ACLR (revision or contralateral) regarding (1) demographics, (2) football-related factors and (3) injury-specific data.
Methods: Players who voluntarily completed a football-specific questionnaire available at the Swedish National Knee Ligament Registry website between April 2017 and September 2020 at the time of their primary ACL injury were included in the study. The questionnaire covered demographics, football-related activities and injury-specific factors.

In the field of muscle fatigue models (MFMs), the prior research has demonstrated success in fitting data in specific contexts, but it falls short in addressing the diverse efforts and rapid changes in exertion typical of soccer matches. This study builds upon the existing model, aiming to enhance its applicability and robustness to dynamic demand shifts. The objective is to encapsulate the complexities of soccer dynamics with a streamlined set of parameters.
