Analysis of bifurcations (branchings). Angle of the axis of the daughter branch with the axis of the mother branch as a function of the ratio of lumen radii (rimother/ridaughter). a Control and exercised males; b control and exercised females. Note that smaller daughter branches tend to deviate more from the course of the mother branch (angles closer to the perpendicular 90°), while larger daughter branches tend to follow the course of that of the mother branch (approximately 180°). Pearson correlations were significant in all four groups, with no significant differences between groups
