title: Mobile velocity-controlled respirometer: description and performance capabilities.
abstract: An apparatus modeled after the Scram respirometer designed by Corcoran is described in terms of design, specifications and performance capabilities. The results with the use of this apparatus in a study of 14 able-bodied adults of five controlled walking speeds are compared to those of a similar study previously reported by Corcoran and Brengelmann. Oxygen consumption (ml O2/kg body wt/min) increases proportionately to the square of the velocity of walking. Results of the two investigations are parallel, although the present report demonstrates a greater male-female difference at all speeds. Uses and limitations of the apparatus are considered.
