Influence of the base-line determination on work efficiency during submaximal cycling.

Abstract

The high WE values determined using the actual VO(2) measurement could be explained by (i) the additional energy expended to stabilise the body in addition to the energy expenditure of moving the lower limbs without power production and by (ii) the difficulty to experimentally reproduce the unloaded condition. The large range of WE values measured in the present study is due to differences in the procedures used to determine the unloaded VO(2) (and thus differences in unloaded VO(2) values) as well as differences in the cycling intensities.
