The influence of exercise on the mechanical function of the heart has become a topic of considerable interest over recent decades. In a recent issue of Medicine and Science in Sports and Exercise, Huang et al. (2) published a study that investigated the effects of high intensity interval training (HIIT) on echocardiographic-derived indices of left ventricular (LV) mechanical function in young, sedentary but otherwise healthy men. We believe that this study has the potential to further our understanding on how the heart responds to exercise, and it ultimately fits within the current knowledge on exercise-induced cardiac adaptation in health and disease (4). However, given the proposed conclusions, we would appreciate additional details from the authors on the methodology used that may have contributed to some unusual results. Specifically, this letter serves to highlight our concerns regarding the two most notable findings reported in the paper by Huang et al (2), namely 1) the unusually large increase in cardiorespiratory fitness following the HIIT intervention, and 2) the exceptionally low values derived from speckle tracking echocardiography.
