It is of interest both in athletics and in the design of man-driven machines to know the properties of the human power. Extensive physiological observations have been made on the properties of the human power. However, in most cases the power is measured in single movements or in brief bouts of exercises, and the properties are ordinarily expressed as a maximal oxygen intake per minute (maximal aerobic power) or as a maximal external work output per unit time. The first systematical investigation relating to the properties of the power output and its maximal duration in the various intensities of exercises involving a large mass of muscle was carried out by GroBe-Lordemann and Muller (1937)^<3)>. They used their own devised bicycle ergometer and found the relation between the mean external work output during exercise and its maximal duration. Recently, Wilkie (1960)^<8)> has examined the properties of man considered purely as a source of mechanical power. He deduced from the published literature the relation between the usable external power output and its duration. 1:'he purpose of the present investigation is likewise to know the properties of the power output and its maximal duration. However, the present investigation was experimentally carried out; each subject was loaded with the various intensities of the exhaustive cycling exercises. The power is expressed as a produced energy in the body per unit time, which was calculated directly from the mean total oxygen intake during exercise and the oxygen debt per endurance time of exercise. Hence, the effects on the power output during exercise and its duration, of the work efficiency, the skills of subjects and the environmental conditions, are less than when the power is measured as an external work output per unit time.
