HR and RPE. AUC – HR, RPE and HR/RPE in hypoxia and hypoxia + CHO conditions for n = 8 volunteers. 1(a) represents the AUC of Heart Rate, and 1(b) the Heart Rate during the different minutes. 2(a) represents the AUC of Rating Perception of Exertion, and 2(b) the Rating Perception of Exertion during the different minutes. 3(a) represents the AUC of the ratio of Heart Rate/Rating Perception Exertion, and 3(b) corresponds to the ratio of Heart Rate/Rating Perception Exertion during the different minutes. The results represent the mean ± SD. * different from Hypoxia, (a) different from Rest; (b) different from 10 min at Hypoxia Group; (c) different from 20 min in Hypoxia + CHO group
