Figure 2. Brachial and carotid artery diameter and wall thickness in healthy recreationally active controls and elite squash players.
Note the similar diameter and wall thickness between the dominant and non-dominant arm in controls, whereas squash players demonstrated a larger diameter in the dominant arm and smaller wall thickness in both arms. In addition, effects of exercise on arterial wall thickness seem to be more pronounced in peripheral arteries than the carotid artery. The Figure provides a summary of the results described in [61].
