We used admittance plethysmography to evaluate hemodynamic changes in the brachial region in response to a dumbbell exercise. Hemodynamic changes were assessed as the change in tissue blood (ΔVdc) calculated from the DC component of the bio-admittance, the pulse wave height (ΔVac) calculated from the pulsatile (AC) component of the bio-admittance, and the arterial blood flow (ABF) calculated from the first derivative of the bio-admittance pulse wave. The change in vascular tone caused by the metabolic vasodilatation was evaluated using d/a, which is the ratio of post-systolic negative waves to early-systolic positive waves and is derived from the second derivative of the bio-admittance pulse wave. Both ΔVdc and ΔVac were significantly increased after the dumbbell exercise. ABF also was increased after the exercise, but not significantly. Furthermore, d/a was increased significantly after the dumbbell exercise, indicating that metabolic vasodilatation caused angiohypotonia in the active muscles. These results suggest that admittance plethysmography is useful for assessing hemodynamics in exercise-induced hyperemia.
