| Research Abstract |
To investigate the integrative physiological linkage among ventilatory, circulatory, and metabolic functions during the locomotion with varying sinusoidal speed at the periods for 1, 2, 5, and 10 min, fours experimental verifications would be accomplished. The abrupt and additional ventilatory response could elicit during sinusoidal walking rather than during sinusoidal cycling. The underlying mechanism, by which the supura-spinal locomotion center would contribute on in partly during human locomotion, was testified compared to human cycling. Secondly, aging and hypoxic exposure directly reflected on the central ciriculatory response, i.e., heart rate, rather than gas exchange kinetics, the delayed HR kinetics during sinusoidal walking was attributed to the sympathetic activation in the elderly individuals. Thirdly, kinetics of capillary blood flow in exercising muscle using the NIRS technique became significantly faster than HR and gas exchange kinetics and could be compensated on the delayed ventilatory and gas exchange kinetics during human locomotion.
