Steady-state vasodilation in response to rhythmic twitch contractions at 2 Hz and 4 Hz in WT and Cav2^−/− mice. Vasodilator Capacity calculated as described in methods. Across vessel branch orders, diameter changes were 5–10 μm during 2-Hz contractions and 15–20 μm during 4-Hz contractions with no differences between WT and Cav2^−/− mice. Summary data are means ± SE; n = 5 per group. #P < 0.05 for contraction duration across groups.
