Abstract(s)
This study aimed (i) to verify if using and carrying a portable gas analyzer (PGA) con strained the performance of school children on the multistage 20-m shuttle run test (20mSRT), (ii) to
verify which peak oxygen consumption (VO2peak) predictive equations have greater agreement
with VO2peak values measured by direct oximetry using the 20mSRT. The study participants were
130 children ((67 boys (age 7.76 ± 0.97 years) and 63 girls (age 7.59 ± 0.91 years)), who performed
two randomized trials of the 20mSRT with and without a PGA. Twenty-two predictive equations
predicted the VO2peak values through the performance of the test with and without a PGA. Without
a PGA, lower values of maximal speed (MS), total laps (TL), and total time (TT) were found for girls
than for boys with a PGA. Only six equations were considered to correctly predict VO2peak. In
general, higher MS, TL, and TT values were found with the use of a PGA. The predicted VO2peak
values from the 20mSRT varied significantly among the published predictive equations. Therefore,
we suggest that the six equations that presented satisfactory accuracy could be practically used to
examine cardiorespiratory fitness in schools and in research with large populations when direct
measurement of VO2peak is not feasible.
