Exercise-training induced remodeling of rat intramural coronary arterioles. Geometrical and elastic alterations in the passive state compared with sedentary controls. Transmural pressure is plotted against outer diameter (a), inner diameter (b), wall thickness (c), tangential wall stress (d), incremental distensibility (e), and incremental tangential elastic modulus (f). Mean values were used from 2-way ANOVA tests with Tukey paired comparisons: * p < 0.05 between sedentary (n = 25) and exercised (n = 12) groups.
