Resumo(s)
This study explored in the 50m races of the four swimming strokes the performance
parameters and/or technical variables that determined the differences between swimmers
who reach the finals and those who do not. A total of 322 performances retrieved from the
2021 Budapest European championships were the focus of this study. The results of the
performances achieved during the finals compared to the heats showed that the best
swimmers did not excel during the heats, as a significant progression of performance was
observed in most of the strokes as the competition progressed. Specifically, combining
men and women, the swimmers had in freestyle a mean coefficient of variation (CV) of
~0.6%, with a mean range of performance improvement (Δ%) of Δ = ~0.7%; in
breaststroke a mean CV of ~0.5% and Δ = −0.2%; in backstroke a mean CV of
~0.5% and Δ = −0.6%, and; in butterfly a mean CV of ~0.7% and Δ = −0.9%. For all
strokes, it was a reduction of the underwater phase with the aim of increasing its speed.
However, this result was not always transferred to the final performance. In any case, most
of the swimmers tried to make improvements from the start of the race up to 15 m.
Furthermore, the swimmers generated an overall increase in stroke rate as the rounds
progressed. However, a decrease in stroke length resulted and, this balance appeared to
be of little benefit to performance.
