Letter to the Editor

Dear Editor,

We read with great interest the study by Holloway et al. (2018), which evaluated the progression of vascular and cardiac changes over a 6-week high-intensity interval training (HIIT). They found no differences in structural and functional cardiac, arterial stiffness and cardiometabolic risk after 6 weeks of HIIT. We would like to respectfully add some comments and contributions to this article.

Although several studies have investigated the effects of different types of exercise training on arterial stiffness (Ashor et al. 2014; Pierce et al. 2018), few studies have used HIIT protocols. According to Ashor et al.’s (2014) review, only two studies investigated the effects of HIIT on PWV, and none on AIx. In this review, the metaregression and subgroup analyses have shown that changes in PWV were associated with higher values of PWV at baseline (> 8 m/s versus ≤ 8 m/s, p = 0.01). Also, there was statistical tendency of association between the changes in PWV and the length of...
