Does intensity really matter regarding aerobic exercise reductions in wave reflection and central hemodynamics?Commentary on“The effect of acute aerobic exercise on central arterial stiffness,wave reflections,and hemodynamics in adults with diabetes:A randomized cross-over design”by Way et al.

摘要

We read with great interest the study by Way et al.1 published in this journal,which described and compared the acute changes in central arterial stiffness(AS),wave reflections,and central hemodynamics(CH)in response to a bout of high-intensity interval exercise(HIIE)and moderate-intensity continuous exercise(MICE)in adults with diabetes.The authors reported a significant reduction in augmentation index(AIx)corrected by a heart rate(HR)of 75 beats/min(AIx@75)and central systolic blood pressure after HIIE,without significant changes in the pulse wave velocity(PWV).In view of this important research topic and our recent contributions to it,we would like to raise some points of discussion that might help to better elucidate the findings observed in the current study,and also suggest pertinent directions to further studies.
