The present study is primarily concerned with the maximum work capacity, in particular with aerobic work capacity. As known under the term maximum oxygen intake, the maximum aerobic work capacity determines capacity of respiro-circulatory adjustment resulting in the maximum delivery of oxygen to the active tissue. In order to evaluate such an aerobic work capacity, two major methods are generally employed: one is the measurement of maximum oxygen intake under the maximal load, and the other is the amount of work possible under a given submaximal load, e.g. PWC_<170> test. Since the former requires an exhaustive work, it may not be applicable to such handicapped people as patients and aged persons. With the aim to avoid this disadvantage, the submaximal work test like PWC_<170> has been developed, being based upon such a hypothesis that increase in heart rate would be linearly related to increase in work intensities. However, its linearity does not always give full satisfaction. Thus, each has its advantage and disadvantage. But it can be said that the maximal load provides more consistent and direct measurement relayed to the maximal work capacity.
