Physiological cost index of walking in able-bodied adolescents and adults

摘要: Fifty-four able-bodied adolescents and 40 adults were assessed in the gait laboratory using an infrared telemetry system. Physiological Cost Index (PCI) of walking ranged from 0.15 beats/metre (b/m) to 0.65 b/m (mean 0.35 b/m, SD 0.09) 0.2 0.55 0.36 0.08) adults. There was no significant difference between median values PCI two study groups. It would appear that range is similar for all age Adult males showed lower than adult females (males 0.31 0.07 0.4 0.07; p < 0.001). Quetelet each subject taken into consideration order standardize subjects' body mass height. correlation either group.Estimation a convenient reliable method monitor changes energy expenditure walking, relatively easy does not require elaborate instrumentation.
