Reply to Gronwald et al.: Exercise intensity does indeed matter; maximal oxygen uptake is the gold-standard indicator

Year: 2018

Abstract: There is no doubt that Gronwald et al.’s (1) message that exercise intensity does matter is true; however, we must respectfully disagree with their claim that the exercise intensity in our study (2) was not actually “very light.” Unlike most interventions in the field, with laboratory (pedaling) exercise testing, the workload is precisely determined based on individually measured cardiorespiratory fitness (CRF) to attain a target intensity. The gold-standard measure of CRF is maximal oxygen uptake ( V . O 2 max ), established by Astrand et al. in the 1950s (3), not maximal heart rate (HRmax). As we emphasized in our article (2), we have established an acute-exercise model based on individual peak oxygen uptake ( V . O 2 peak ) and demonstrated the benefits of exercise on human cognitive … [↵][1]2To whom correspondence may be addressed. Email: myassa{at}uci.edu or soya.hideaki.gt{at}u.tsukuba.ac.jp.
