High-intensity intermittent training versus moderate-intensity intermittent training: is it a matter of intensity or intermittent efforts?

High-intensity intermittent training (HIIT) has gained popularity in recent years for its similar or higher effects compared with aerobic continuous training (ACT) or controls in different age groups, several health-related parameters and cardiovascular diseases (CVD)1–3 as well as in competitive athletes.

‘Intensity’ is not the only difference between HIIT and continuous training

To analyse the role of HIIT comparing HIIT group with controls is an adequate approach for describing acute or chronic responses to a particular training model. However, when aiming to compare the efficacy of two training regimens, it has been usual to compare HIIT with ACT.1 In those cases, authors explained the differences largely on the grounds of intensity.4 However, we highlight that these studies compared two training modalities which are different in their training intensity and in the stimulus type—intermittent versus continuous.
