Left atrial mechanics and aortic stiffness following high intensity interval training: a randomised controlled study.

Purpose: High intensity interval training (HIIT) has been shown to improve important health parameters, including aerobic capacity, blood pressure, cardiac autonomic modulation and left ventricular (LV) mechanics. However, adaptations in left atrial (LA) mechanics and aortic stiffness remain unclear.

Methods: Forty-one physically inactive males and females were recruited.
