“…Eighteen studies were performed in a hypoxic chamber (Asmaro et al, 2013;Kim et al, 2015;Seo et al, 2015;Lefferts et al, 2016;Legg et al, 2016;Valk et al, 2016;Beer et al, 2017;Feeback et al, 2017;Seo et al, 2017;Decroix et al, 2018;Reményi et al, 2018;Gerhart et al, 2019;Williams et al, 2019;Seech et al, 2020;Blacker and McHail, 2021;Blacker and McHail, 2022;Chroboczek et al, 2022;Falla et al, 2022;Kerr et al, 2022), 16 with a breathing mask that induced hypoxia (Turner et al, 2015a;Noble et al, 1993;Ochi et al, 2018;Malle et al, 2016;Lei et al, 2019;Caldwell et al, 2018;Hewett et al, 2010;Legg et al, 2012;Ogoh et al, 2018;Stepanek et al, 2013;Nakata et al, 2017;Loprinzi et al, 2019;Kourtidou-Papadeli et al, 2008;Turner et al, 2015b), two studies were performed at altitude (Wang et al, 2013;Davranche et al, 2016), one both at altitude and in a chamber (Kammerer et al, 2018), and one both in a chamber and with a breathing mask (Rossetti et al, 2021). The exposure duration ranged from 10 min to 6.5 h with 92% of studies using durations of <3 h. The data points obtained were divided into exposure to normobaric hypoxia (133; 67%) and hypobaric hypoxia (66; 33%).…”
