Energy balance

Low muscle glycogen availability prior to soccer match-play causes early fatigue, characterized by reduced high-intensity sprinting and increased low-intensity walking, whereas maintaining normal glycogen stores preserves high-intensity performance.

Ensure you have high muscle glycogen stores before kickoff. If you start with low glycogen, you will likely slow down, walk more, and sprint less effectively. Prioritize carbohydrate intake in the days leading up to the match to maintain 'normal' glycogen levels and preserve high-intensity performance.

GoodSupportsHIGH confidence
Investigations from the early 1970’s [22] first demonstrated that players starting a soccer match with low muscle glycogen availability fully deplete their stores by the end of the match... This results in an early onset of fatigue characterised by a significant increase in time spent at low intensity movement such as walking (50% vs. 27% of total distance), and an inability to complete sprinting activities (15% vs. 24% of total distance) compared to those who started the match with ‘normal’ glycogen availability.

Why this rating

Based on multiple cited studies (including early 1970s work and more recent robust investigations) showing consistent trends in glycogen depletion and performance correlation.
