Resumo(s)
Getting fast results from the evaluation of swimmers is one of
the most important goals to achieve with technological development
in the field. The purpose of this study was to validate a
real-time velocimetric device (speedometer) through the comparison
of their results with computer assisted videogrametry.
The sample included 7 international level swimmers (3 females
and 4 males). Each swimmer performed four 25m trials, two at
200m race pace and two at 50m race pace. For each trial, two
stroke cycles were studied, resulting on a total of 28 cycles

analysed. Hip v(t) curves obtained from speedometer and
videogrametry were compared, as well as the speedometer hip
curve with the one of the centre of mass (CM). The higher
mean correlation obtained was between vhip1 and vhip2
(0.955±0.028), followed by vhip1 with vCM (0.920±0.049). The
lower correlation was vhip2 vs. vCM (0.878±0.053). It was concluded
that the speedometer is a reliable, fast and interactive
tool for training advice.
