The aim of the study was to assess the effect of alcohol on the exercise performance of members of the Police of the Czech Republic. Movement performance was assessed through motor tests for movement coordination. The experiment took place in 4 rounds with 5 motor tests, where the 1st round was without alcohol consumption. In the following 3 rounds, each proband received an individual dose of alcohol, which was calculated according to his body weight determined on the day of the experiment. Effect size was assessed by assessing the magnitude of the difference between the performance of the experimental and control groups through a repeated-measures analysis of variance. The results showed that even light or excitable drunkenness affects motor performance, especially in activities requiring speed of execution and the ability to balance.
