Mechanical efficiency of a champion walker
Abstract
Oxygen consumptions were measured on a champion walker, while walking at between 6·4 and 16·9 km / hand while running at between 11.3 and 17.7 km/h. Above 9.7 km /h the curve of oxygen consumption against speed for walking was almost twice as steep as that for running, indicating that even champion walkers are more efficient, mechanically. when running than when walking abol'e 9·7 km/h. The curve for the champion walker was less steep than that for m'!n walking in the normal way above 9-7 km/ h indicating that the technique of 'rolling the pelvis gives competition walkers greater mechanical efficiency. It was also found that the VO2max of the champion walker was higher when running than I"hen walking.
