A single moderate-intensity aerobic exercise session improved endothelial function in both throwers and controls (p<0.001) but reduced arterial stiffness only in untrained controls (p=0.003).
Does a single session of moderate-intensity aerobic exercise improve arterial stiffness and endothelial function in strength-trained throwers compared to untrained individuals?
A single session of moderate aerobic exercise acutely improves endothelial function, but not arterial stiffness, in strength-trained throwing athletes.

Background Arterial stiffness and endothelial dysfunction are early markers of cardiovascular disease (CVD) risk. While moderate-intensity aerobic exercise has demonstrated vascular benefits in untrained individuals, its acute effects on strength-trained athletes remain unclear. Objective This study investigates the impact of a single aerobic session on arterial stiffness and endothelial function in strength-trained throwers and untrained controls. Methods Eleven male university throwers and eleven healthy controls participated. Participants completed 30 min of moderate-intensity cycling at 50% of heart rate reserve. Brachial-ankle pulse wave velocity (baPWV) and reactive hyperemia-peripheral arterial tonometry index (RHI) were measured at baseline, immediately after exercise, and 40 min post-exercise. Results Arterial stiffness decreased significantly in the controls ( p = 0.003) but showed no change in the throwers. Endothelial function, as measured by RHI, improved significantly in both groups post-exercise ( p < 0.001). There was no significant difference in RHI improvement between groups. Conclusions In the throwers group, a single session of moderate-intensity aerobic exercise did not lead to a significant reduction in arterial stiffness but resulted in an improvement in endothelial function. These findings suggest that while endothelial function in strength-trained throwers can benefit acutely from aerobic exercise, their arterial stiffness may require more intensive or longer-duration aerobic interventions to achieve significant improvements.
