This may suggest that more complex tasks with a higher number of passes might negatively be affected by low doses of caffeine ingested one hour before playing." Moreover, most of the participants scored lower on decision-making and the Loughborough Soccer Passing Test after consuming caffeine. Negar Jafari, from Shiraz University, said, "While the short pass accuracy remained consistent among almost all participants before and after caffeine consumption, the performance varied in the case of long passes. However, participants' decision-making was 7.14% lower and the Loughborough Soccer Passing Test scores were 3.49% lower when they consumed caffeine compared to the placebo. The soccer players were 1.67% more accurate in short passes and 13.48% more accurate in long passes when they consumed caffeine compared to the placebo. The participants completed the tasks once after taking 3 mg/kg body mass of caffeine and once after consuming similar amounts of placebo. The researchers then used a computer task to measure decision-making in different gameplay scenarios, with participants asked to determine the best outcome of ten simulated pre-recorded events. Participants performed five short (10m) and five long (30m) passes, as well as the Loughborough Soccer Passing Test, which assesses skills including passing, dribbling, control, and decision-making. Twelve young soccer players, aged between 16–17 years old, took part in a series of tasks to explore the impact of caffeine on decision-making and passing accuracy. "However, the effects of caffeine on 'higher' cognitive functions such as problem-solving and decision-making are often debated, so we decided to investigate this." Studies have shown that caffeine can enhance attention, accuracy, and speed, as well as self-reported measures of energy and mood. Pooya Soltani, Senior Lecturer in Games Technology at Staffordshire University, explained, "Caffeine is one of the most popular dietary supplements which has been shown to provide benefits during exercise, including soccer. DOI: 10.1016/j.bbr.2023.114732Ī study published in the Behavioural Brain Research by Staffordshire University and Shiraz University in Iran has found that while consuming caffeine before a game can improve the accuracy of soccer passes, it can have an adverse effect on more tactical play involving a higher number of passes.ĭr. Credit: Behavioural Brain Research (2023). These coefficients indicate reasonable reliability. Each participant repeated each pass five times, and the average of the five shots determined their score for short and long passes. The distance from the cone determined the point for the players hitting the cone would be 4 points, missing within 1 m would be 2 points, and more than 1 m would be without any points. For measuring pass accuracy, participants dribbled for 5 m and passed the ball towards cones at 10 m (short pass) or at 30 m (long pass). The order and duration of stimuli for the decision-making task.
