Article Synopsis
  • The systematic review investigates how carbohydrate (CHO) intake affects soccer players' physical performance, cognitive function, and muscle glycogen levels, as well as possible differences between male and female players.
  • A search of scientific literature found 61 relevant articles, adhering to established review guidelines, which led to the discovery that CHO consumption enhances speed, sprinting ability, and mental performance, while there is no clear impact on skills like dribbling and passing.
  • It is advised that players consume specific amounts of CHO before, during, and after matches to maintain performance and recovery, particularly noting that female players may misjudge their energy needs and should adjust their CHO intake accordingly.

Sleep is essential for health, especially during adolescence. However, most adolescents do not obtain the recommended 8 to 10 h of sleep, and their health is significantly affected. While both physical activity (PA) and diet have been shown to help improve the sleep quality and duration, the combined association of these two factors with sleep has yet to be analysed.

(1) Background: The main goals of this study were to describe the physical activity (PA) and sleep habits of 8-12-year-old children according to their gender and to evaluate the relationship between PA and sleep habits (i.e., duration and timing).

This study aimed to validate the use of a single blood lactate concentration measure taken following a 12 km h running stage (BLC) to predict and monitor fixed blood lactate concentration (FBLC) thresholds. Three complementary studies were undertaken. Study I: the relationships between BLC and the running speeds at FBLC of 3 mmol L (S3mM) and 4 mmol L (S4mM) measured during a multistage running field test were examined in 136 elite athletes.

Dehydration hastens the decline in cerebral blood flow (CBF) during incremental exercise, whereas the cerebral metabolic rate for O2 (CMRO2 ) is preserved. It remains unknown whether CMRO2 is also maintained during prolonged exercise in the heat and whether an eventual decline in CBF is coupled to fatigue. Two studies were undertaken.

The aim of this study was to investigate whether the speed associated with 90% of maximal heart rate (S90%HRmax) could predict speeds at fixed blood lactate concentrations of 3 mmol·L(-1) (S3mM) and 4 mmol·L(-1) (S4mM). Professional team-sport players of futsal (n = 10), handball (n = 16), and basketball (n = 10) performed a 4-stage discontinuous progressive running test followed, if exhaustion was not previously achieved, by an additional maximal continuous incremental running test to attain maximal heart rate (HRmax). The individual S3mM, S4mM, and S90%HRmax were determined by linear interpolation.

This study compared anthropometric (body height, body mass, percent body fat, fat-free body mass) and physical fitness characteristics (vertical jump height, power-load curve of the leg, 5 and 15 m sprint running time and blood lactate concentrations ([La](b)) at submaximal running velocities) among 15 elite male indoor soccer (IS) and 25 elite male outdoor soccer (OS) players. IS players had similar values in body height, body mass, fat-free body mass and endurance running than OS players. However, the IS group showed higher (P < 0.
