Figure 5. Effect of endurance training (ET) and sprint interval training (SIT) on systemic wave reflections and central and peripheral artery stiffness.

A, systemic wave reflections measured using augmentation index normalised to 75 bpm (AIx@75bpm) following ET and SIT. B, central artery (aortic) stiffness measured using pulse wave velocity (PWV) following ET and SIT. C, peripheral artery (brachial artery) stiffness measured using pulse wave velocity following ET and SIT. *P < 0.05, main effect of training.
