They attributed our results to limitations of the homeostasis model assessment in assessing insulin sensitivity.The homeostasis model assessment does have limitations, but we are confident that our conclusion remains well supported. This stems from the correlation of the homeostasis model assessment with signaling and metabolic markers measured in our study.1 There is little conclusive evidence for more favorable effects with aerobic interval training than with continuous moderate exercise in the literature, although there are some studies that suggest that high-intensity training provides more benefits to insulin action compared than does moderate/low-intensity exercise.4,5 However, these studies do not exclusively involve patients with metabolic syndrome. Moreover, it is difficult to compare the different studies, as our definition of moderate-intensity exercise (≈70% of maximum heart rate) corresponds to their definition of high-intensity exercise (65% to 80% of peak blood oxygen level).4,5 As discussed in our original article,1 larger multicenter studies with similar protocol should be performed to clarify this important issue.DisclosuresNone.
