The efficacy of a discontinuous graded exercise test in measuring peak oxygen uptake in children aged 8 to 10 years
Abstract
As children's natural activity patterns are highly intermittent in nature, and characterised by rapid changes from rest to vigorous physical activity, discontinuous exercise tests may be considered ecologically valid for this population group.This study compared the peak physiological responses from a discontinuous and continuous graded exercise test (GXT_D, GXT_C, respectively) during treadmill exercise in children.Twentyone healthy children (9.6 ± 0.6 y) completed GXT_D and GXT_C in a randomised order, separated by 72-hours.Following each GXT, and after a 15-minute recovery, participants completed a verification test at 105% of the velocity attained at peak oxygen consumption (VO 2 peak).There were no differences in VO 2 peak (55.3 ± 8.2 cf.54.4 ± 7.6 mL•kg -1 •min -1 ) or maximal heart rate (202 ± 10 cf.204 ± 8 b•min -1 ) between GXT_C and GXT_D, respectively (P>.05).Peak running speed (10.7 ± 0.9 cf.12.1 ± 1.3 km•h -1 ) and respiratory exchange ratio (1.04 ± 0.05 cf.0.92 ± 0.05) were however different between tests (P<.001).Although similar peak physiological values were revealed between GXT_C and the corresponding verification test (P>.05),VO 2 peak (53.3 ± 7.3 mL•kg -1 •min -1 ) and heart rate (197 ± 13 b•min -1 ) were significantly lower in the GXT_D verification test (P<.05).In conclusion, a discontinuous GXT is an accurate measure of VO 2 peak in children aged 8 to 10 years and may be a valid alternative to a continuous GXT, despite its longer duration.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
