This study aimed to understand whether there are significant differ-
ences in stroke kinematics between tiers in female swimmers com-
peting in the four 50 m events of the 2021 European Championships
and to understand the speed-time relationship in the four race events
per tier. Participants were all female swimmers (backstroke: 78 swim-
mers; breaststroke: 75 swimmers; butterfly: 74 swimmers; freestyle:
87 swimmers) who participated in the 50 m events at the 2021 LEN
European Championships held in Budapest (i.e. heats, semi-finals,
and final). For each swimming stroke, swimmers were divided into
three tiers (best-performing swimmers, intermedium-performing
swimmers, and poorest-performing swimmers). Swimming speed
revealed a significant tier effect (p < 0.05) in all race sections for all
swimming strokes. The other stroke kinematic variables revealed
divergent findings, but the stroke frequency presented an overall
tier effect (p < 0.05) across all four swimming strokes. Curve fitting for
all swimming strokes and tiers revealed a cubic relationship. Thus, it
should be considered that female swimmers who compete in 50 m
events in major competitions adopt an all-out strategy. The present
data provide coaches with insightful information about the main
trend in 50 m sprint events, specifically in each section of the race.
