| Outline of Final Research Achievements |
To explore the coordinating mechanism of cardiorespiratory system during exercise, the dynamics of main physiological variables in response to sinusoidal-varied work rate exercise using by solely upper (i.e. cranking) or lower (i.e. cycling) limb, and both combined were examined. The responses of the circulation to non-active limb (i.e. brachial artery (BA) during lower limb cycling) and brain (i.e. middle cerebral artery (MCA)) were specially focused. The results summarized that; 1) within the sub-maximal exercise domain, the responses of combined exercise simultaneously using the upper and lower limbs were substantially summed by both responses, and 2) the circulatory responses of BA and MCA were clearly followed as sinusoidal form, but the dynamic characteristics (phase delay and amplitude) in BA were approximately anti-phasic with a relatively large amplitude, whereas those in MCA were very stable with a short delay.
