The aim of this study was to: (i) characterise the stroke kinematics' stability of the male swimmers competing in the four 50 m events at the 2021 European Championships, and; (ii) understand the speed-time relationship in the four race events.All male swimmers who participated in the 50 m events (backstroke: 78 swimmers; breaststroke: 79 swimmers; butterfly: 89 swimmers; freestyle: 95 swimmers) were evaluated.In each swimming stroke swimmers were split in two groups (better and poorer performances).Significant variances (p < 0.05) were observed in both groups in all variables and for all swimming strokes.Swimming speed was the variable with the highest variance in both groups and strokes.Overall, better swimmers presented a low to high normative stability, and poorer swimmers a moderate-to-high.Speed-time curve fitting for all swimming strokes and groups suggested a cubic relationship.It can be considered that elite male swimmers racing 50 m sprint events at major competitions present an all-out trend.The present data provide coaches with substantial information about the main trend in the 50 m sprint events, specifically in each section of the race.
