The relative age effect (RAE) is a well-documented phenomenon in both team and individual sports; however, evidence in squash remains minimal.

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...
