Effect of 4 days of pre-competition carbohydrate loading on performance indicators (running distance, speed, number of repetitions of speed, body pressure) of soccer players: evidence based on GPS data.
Investigating whether short-term carbohydrate intake with a focus on loading can lead to improved performance in soccer players
Design
The present research has a control group, one side blind, randomized by lottery on 22 Premier League soccer players.
Settings and conduct
This project will be carried out in one of the football league teams in Tehran. For this purpose, 22 players are randomly divided into two groups receiving carbohydrates and control. Training is designed considering one game per week. Players then begin carb-loading four days before the race. GPS devices specific to football will be used to check performance indicators.
Participants/Inclusion and exclusion criteria
Premier League football players who had at least 3 years of playing experience in the Premier League.
Intervention groups
The intervention group consisted of carbohydrate loading, where they consumed 4.5 grams of carbohydrates per kilogram of body weight four days before the competition. The control group will not receive any intervention during the research and will use a normal diet of 50% carbohydrates, 30% protein, and 20% fat.
Main outcome variables
Running distance, number of running starts, metabolic power, average metabolic power, body pressure.
