Heart rate (HR, A,B) and systolic and diastolic blood pressure (C,D) during the first (S1) and the third (S3) sustained or intermittent hypoxia sessions. Data points are means ± SD. Gray areas indicate hypoxic phases. *Significantly different from normoxic baseline in both S1 and S3 (p < 0.05, two-way ANOVA main effect of time); +Significantly different from normoxic baseline in S3 only (p < 0.05, two-way ANOVA session × time interaction); $Significant difference between S1 and S3 (p < 0.05, two-way ANOVA session × time interaction).
