The level of adaptation to walking may be assessed by means of energy cost, c. The variable c was studied during walking on a treadmill in two groups of visually handicapped children (international classification of vision of 5/2000 or less).
The two groups were comprised of 15 boys (mean age = 11.8±2.1 years) and 13 girls (mean age =11.6±3.1 years). Both values of c were not significantly higher than the energy cost of untrained non-handicapped children of the same age.
There was a U-shaped dependence c on increased speed of walking. It is concluded that in visually handicapped children the energy cost of walking, and thus adaptation to walking, is the same as in the healthy children.
