The main purpose of this study was to develop the new techniques of work rate forcing for estimating the aerobic working capacity of humans. The proposed techniques are based on ; 1) the sinusoidally fluctuated work rate forcing which simulates the non-steady state physical activities of daily life, and 2) the exponentially incremental work rate forcing, as an alternative way to the conventional ramp-mode exercise test With respect to the sinusoidal exercise, the responses of O2-cascade related variables(i. e. from pulmonary VO2 to O2-utlization in active muscle) and their coordination were examined. Furthermore, the physiological linkage, that is, circulatory adjustments among the O2-cascade related and non-related variables(including the cerebral and non-exercising limb circulations) were explored.
