| Abstract | The purpose of this work was to apply a simple
method for acquisition of power output (PO)
during the Wingate Anaerobic Test (WAnT) at a
high sampling rate ( S R ) and to compare the effect
of lower S R
on the measurements extracted from
the PO. 26 male subjects underwent 2 WAnTs on
a cycle ergometer. The reference PO was calcu-lated at 30 Hz as a function of the linear veloc-ity, the moment of inertia and the frictional load.
The PO was sampled at 0.2, 0.5, 1, 2 and 5 Hz.
Both the peak (16.03 ± 2.22 W · kg
−1
) and mean
PO (10.34 ± 1.01 W · kg
−1
) presented lower rela-tive values when the S R
was lower. Peak PO was
attenuated by 0.29 – 42.07 % for decreasing sam-pling rates, resulting in different values for 0.2
and 1 Hz ( P< 0.001). When the S R
was 0.2 Hz, the
time to peak was delayed by 53.81 % ( P< 0.001)
and the fatigue index was attenuated by 22.12 %
( P< 0.001). In conclusion, due to the differences
achieved here and the fact that the peak flywheel
frequency is around 2.3 Hz, we strongly recom-mend that the PO be sampled at 5 Hz instead of
0.2 Hz in order to avoid biased errors and misun-derstandings of the WAnT results. | pt_BR |
