Støren Ø, Helgerud J, Sæbø M, Støa EM, Bratland-Sanda S, Unhjem RJ, Hoff J, Wang E (2017) The effect of age on the V̇O2max response to high-intensity interval training. Med Sci Sports Exerc 49(1):78–85 Tomoyuki Kawada commented on our article “Effect of high-intensity aerobic exercise on aerobic fitness and HbA1c in patients with type 2 diabetes”. First of all, we have not stratified the effect of training intensity by age. The reasons for this are (1) the low number of participants in each age group, and (2) the adaptations to at least high-intensity aerobic interval training (HAIT) have recently been shown to be independent of age (Støren et al. 2017). Second, to select the level of intensity training in patients with T2D from the progress of T2D and lifestyle information, as suggested by Kawada, was not considered appropriate to answer the research problem in our study. On the contrary, we chose to match the two intensity groups by T2D progress, use of medications, etc. This was considered necessary to evaluate the adaptations to the two training regimes as correctly as possible.
