Description
Summary:The merits of the laddermill as an ergometer for measuring man's major physiological responses to work are presented, together with a literature-based summary of other commonly used ergometers. The paper shows that the relationships between oxygen uptake, work rate, pulmonary ventilation, and heart rate can be described in simple linear equations. The linear relationship between the oxygen uptake (energy expenditure) and the work rate for ladder-climbing, cycling, cranking, and running is presented and the more complicated relationship of oxygen uptake to walking speed is discussed. In addition, the linear relationships of oxygen uptake to ventilation and to heart rate are given for arms and legs at submaximal and maximal work levels.
