To measure and compare the oxygen consumption and physiological energy cost of free level walking across healthy children, adolescents, and adults.
Assessed oxygen uptake and heart rate during free level walking in 114 pediatric participants aged 6 to 19 years and compared them to 47 healthy adult controls.
Stratified pediatric participants into two age groups: children (ages 6–12 years) and adolescents (ages 13–19 years).
Mean rate of oxygen uptake was significantly higher in children at 15.3 ml/kg/min compared to adolescents at 12.9 ml/kg/min.
Oxygen cost per meter walked was higher in children than adolescents, averaging 0.22 ml/kg/min versus 0.18 ml/kg/min.
Mean heart rate was significantly elevated in children at 114 bpm compared to adolescents at 97 bpm, directly mirroring the oxygen uptake pattern.

No takes yet. Share an insight, caveat, or question.

Implication

Observational study reveals higher oxygen consumption and heart rate during walking in younger children than adolescents, indicating reduced locomotor efficiency at younger ages.
