Figure 1. Capillarization and presence of proliferating endothelial cells in skeletal muscle before and after passive training of the leg.

Capillary-to-fibre ratio (C:F, A), no. of capillaries around each fibre (B), capillary density (cap mm⁻², C), mean fibre area (μm², D), and Ki-67 positive cells per fibre (Ki-67/fibre, E) before and after 2 weeks and 4 weeks of passive training in the untrained (filled bars) and passively trained (open bars) leg. Values are means ±s.e.m. (n= 7). †P < 0.05 vs. week 0; #P < 0.05 vs. untrained leg week 2; ‡P < 0.05 vs. passively trained leg week 4; §P < 0.05 vs. week 2.
