✦ Synopsis

Normative data that summarize the energy requirements and gait characteristics of level outdoor walking were determined in 1 1 1 normal subjects between the ages of 20 and 80 years. Subjects were divided into two age groups: young adults (20-59 years) and senior subjects (60-80 years). The mean rate of oxygen consumption for young adults and senior subjects did not significantly differ, averaging 11.9 mlikg-rnin for both groups. The data on heart rate paralleled the findings on oxygen consumption, averaging 100 and 103 beats/ rnin, respectively. The net oxygen cost per meter walked for senior subjects, 0.16 ml/kg-m, was significantly greater (p < 0.0005) than the value for young adults, 0.15 ml/kg-m, due to a decline in the average walking speed. The average gait velocity for senior subjects, 73 d m i n , was statistically significantly less (p < 0.0005) than the values for the younger adults, 80 d m i n .
