| Research Abstract |
We examined changes in total hemoglobin response during bicycle exercise at various constant workloads(f-Δ [tHb]) and clarified whether the f-Δ [tHb] indicates a dilation of the vascular bed and/or capillary recruitment or just an increase of skin blood flow.
The kinetics of f-Δ [tHb] was totally different from that of skin blood flow at all workloads, and the f-Δ [tHb] were significantly correlated with the increase of oxygenated hemoglobin(Δ [oxy]) during constant exercise. These results suggest that the increase of [tHb] during constant workloads may be caused by the microvasular expansion in muscle tissue.
