ABSTRACT
This investigation examines the effects of vertical and horizontal loading on the O2 intake (VO2) response of children (n = 8) and adults (n = 8) to treadmill running. In unloaded running, the children required a significantly greater VO2 (P less than 0.001) than the adults [mean difference 7 ml.kg-1.min-1 (18.5%)]. There was no significant difference in the VO2 response of the children and the adults to either vertical or horizontal loading. Vertical loading with 5 and 10% of body mass did not produce a significant increase in the VO2 response of either group. In contrast, horizontal loading produced a significant increase (P less than 0.001) in both groups. The consistent response to the two forms of loading suggests that there is no difference between children and adults in the apparent efficiency of running with an external load. Stride frequency showed a significant increase with vertical loading (P less than 0.001) and a significant decrease with horizontal loading (P less than 0.001) in both groups.
