Contractile and relaxation properties of coronary resistance arteries induced by long-term physical exercise. a Relaxation induced by increasing concentrations of bradykinin at 50 mmHg pressure. (at 10−8 M: Ftraining = 4.391, Fsex = 4.374, Fint = 1.304, dftraining = 1, dfsex = 1, dfint = 1, Ptraining = 0.045, Psex = 0.046, and Pint = 0.263; at 10−7 M: Ftraining = 2.225, Fsex = 3.909, Fint = 0.44, dftraining = 1, dfsex = 1, dfint = 1, Ptraining = 0.147, Psex = 0.058, and Pint = 0.513; at 10−6 M: Ftraining = 3.047, Fsex = 4.99, Fint = 1.746, dftraining = 1, dfsex = 1, dfint = 1, Ptraining = 0.092, Psex = 0.034, and Pint = 0.197). b Contraction induced by L-NAME at 50 mmHg. (Fbetween groups = 5.091, dfbetween groups = 3, Pbetween groups = 0.006). One-way (L-NAME) and two-way (bradykinin) ANOVA with post hoc Tukey’s test. Values are the means ± SEM. *P < 0.05 vs. MSE, $P < 0.05 vs. MEx
