In young people, VO 2peak is reached in the final stage of a maximal effort. 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 VO 2peak is not feasible.Ĭardiorespiratory fitness (CRF) is a component of physical fitness commonly used in schools that can be assessed, in children and adolsecents, through oxygen consumption (VO 2) during a maximal test to obtain the peak oxygen consumption (VO 2peak) value, which is usually recognized as one of the best indicators of aerobic fitness.

The predicted VO 2peak values from the 20mSRT varied significantly among the published predictive equations. In general, higher MS, TL, and TT values were found with the use of a PGA. Only six equations were considered to correctly predict VO 2peak. 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. Twenty-two predictive equations predicted the VO 2peak values through the performance of the test with and without a PGA. 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.

This study aimed (i) to verify if using and carrying a portable gas analyzer (PGA) constrained the performance of school children on the multistage 20-m shuttle run test (20mSRT), (ii) to verify which peak oxygen consumption (VO 2peak) predictive equations have greater agreement with VO 2peak values measured by direct oximetry using the 20mSRT. This information is helpful to strength and conditioning professionals and to schoolteachers if portable gas analyzers are unavailable or if the environment is not suitable for such assessments. In addition, for girls, higher values of maximal speed, total laps, and total time were found when a portable gas analyzer was used. Our results showed that only six predictive equations correctly predicted the peak oxygen consumption. To accomplish these aims, 67 boys and 63 girls were included in the analysis. Furthermore, we verified if wearing and carrying a portable gas analyzer constrained the children’s performances. In the present study, 22 equations were used to determine which predictive equations had greater agreement with VO 2peak values measured by direct oximetry through performance of the 20mSRT. Thus, to avoid using such a device, one possibility is to use equations for predicting peak oxygen consumption, which is recognized as one of the best indicators of aerobic fitness. Moreover, the use of such a device with children is almost impracticable in school environments. Research has often used a portable gas analyzer to measure cardiorespiratory fitness in clinical and scientific settings however, this may not be practical due to the high cost of the device. For children, a simple test that can be used to assess cardiorespiratory fitness is the multistage 20-m shuttle run test (20mSRT). Cardiorespiratory fitness is one of the main components of physical fitness.
