Energy Cost of Walking in Normal Children and Teenagers
Abstract
SUMMARY: Oxygen consumption during free level walking was determined in 114 children and teenaged subjects between the ages of 6 and 19 years and compared with a group of 47 normal adults. Subjects were divided into two age groups: children (6–12 years) and adolescents (13–19 years). The mean rate of oxygen uptake for children was significantly greater, 15.3ml/kg/min, than the value for teenaged subjects, 12.9ml/kg/min. The oxygen cost to walk a unit distance (meter) was higher in children than adolescent subjects. The mean values averaged. 22ml/kg/min and 18ml/kg/min respectively. The data on heart rate paralleled the findings on oxygen consumption. The mean heart rate for children, 114 beats per minute (bpm), was significantly higher than the mean values for adolescent subjects, 97bpm. RÉSUMÉ: Coûte énergétique de la marche chez les enfants et adolescents normaux La consommation d'oxygène durant une marche à vitesse non imposée a été mesurée chez 114 enfants et adolescents âgés de six à 19 ans, et comparée à un groupe de 47 adultes normaux. Les sujets ont été divisés en deux groupes d'âge: les enfants (six à 12 ans) et les adolescents (13 à 19 ans). Le taux moyen de consommation d'oxygène chez les enfants a été significativement plus grand, 15,3ml/kg/min que chez les adolescents 12,9ml/kg/min. La consommation d'oxygène à l'unité de déplacement (métre) a été plus élevée chez les enfants que chez les adolescents. Les moyennes étant respectivement de 0.11ml/kg/m et 0.18ml/kg/m. Les données concernant le rythme cardiaque suivaient les variations de consommation d'oxygène. Le rythme moyen pour les enfants, 114 battements par minute (bpm) était significativement plus élevé que chez les adolescents, 97bpm. ZUSAMMENFASSUNG: Energieverbrauch beim Spazierengehen bei Erwacnsenen und Teenagern Bei 114 Kindern und Teenagern im Alter zwischen sechs und 19 Jahren wurde der Sauerstoffverbrauch beim normalen Spazierengehen bestimmt und verglichen mit einer Gruppe von 47 gesunden Erwachsenen. Die Probanden wurden in zwei Altersgruppen eingeteilt: Kinder (sechs bis 12 Jahre) und Heranwachsende (13 bis 19 Jahre). Der mittlere Sauerstoffverbrauch war bei Kindern signifikant höher, 15.3ml/kg/min, als bei den Teenagern, 12.9ml/kg/min. Der Sauerstoffverbrauch zum Zurücklegen einer Entfernungseinheit (Meter) war bei Kindern höher als bei den Heranwachsenden. Die mittleren Werte lagen durchschnittlich bei 22ml/kg/min bzw. 18ml/kg/min. Die Werte der Herzfrequenz entsprachen den Befunden über den Sauerstoffverbrauch. Die mittlere Herzfrequenz für Kinder lag mit 114 Schlägen pro Minute (bpm) signifikant höher als der Mittlewert für Heranwachsende, 97bpm. RESUMEN: Coste en energía de la marcha en niños normales y en adolescentes Se determinó el consumo de oxígeno durante la marcha con nivel libre en 114 niños y adolescentes de 6 a 19 años y se comparó con un grupo de 47 adultos normales. Los individuos se dividieron en dos grupos de edad: niños (6–12 años) y adolescentes (13–19 años). El promedio de consumo de oxigeno en niños fue significativamente mayor (15.3ml/kg/min) que el de los adolescentes (12.9ml/kg/min) El costo de oxígeno para andar una unidad de distancia (un metro) era mayor en niños que en adolescentes. Los valores promedio eran de 22ml/kg/min y 18ml/kg/mil respectivamente. Los datos sobre la frecuencia cardiaca eran paralelos con los del consumo de oxígeno. El promedio de la frecuencia cardiaca en niños (114 por minuto) era significativamente mayor que los valores hallados en adolescentes (97 por minuto).

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.
