Figure 1.

Schematic hypothesized representation of capillary red blood cell flux (F_RBC) and velocity (V_RBC) during recovery from muscle contractions in the presence (circles) or absence (dashed lines) of a muscle pump effect on capillary hyperaemia. Open circles: ‘mirror image’ of data from Kindig et al. (2002) for capillary haemodynamics following the onset of exercise. Note that the y-axis was modified to be visually equivalent to the profiles expected during recovery from contractions. Dashed lines: theoretical representation assuming a delay before the onset of changes in arteriolar diameter (Gorczynski & Duling, 1978; Bearden et al. 2004).
