Functional adaptations of the brachial artery in college baseball players
Tsukuba, Japan—The arteries of athletes demonstrate adaptations in structure and function corresponding to the physical characteristics of the sport. For instance, baseball players repeatedly perform high-intensity throwing motions during daily practice and games, suggesting that some form of exercise-induced adaptation could occur, particularly in the brachial artery of the dominant (throwing) arm. However, such adaptations have not been investigated in detail. In this study, researchers focused on exercise-induced arterial adaptations in university baseball players, specifically examining the various functions of brachial artery vascular endothelial cells in maintaining vascular health.
The researchers measured vascular endothelial function in the brachial artery, shoulder joint range of motion, and muscle strength of the dominant arm in 23 pitchers and 67 fielders. The results showed that, compared to fielders, pitchers exhibited significantly poorer vascular endothelial function in the brachial artery. Furthermore, a significant negative correlation was observed between the shoulder external rotation range of motion and internal rotation muscle strength and vascular endothelial function.
These differences between pitchers and fielders suggest exercise-induced functional arterial adaptations in the brachial artery. Understanding these athlete-specific functional arterial adaptations might aid in developing more effective training strategies and preventive measures for internal medicine-related sports injuries.
