	Pre-IH	Post-IH	P Value
Heart rate, beats/min	60 ± 2	62 ± 2	0.06
Systolic blood pressure, mmHg	139 ± 2	140 ± 2	0.77
Diastolic blood pressure, mmHg	77 ± 2	78 ± 2	0.04
Mean blood pressure, mmHg	98 ± 2	100 ± 2	0.09
Breathing frequency, breaths/min	12 ± 1	13 ± 1	0.14
Tidal volume, mL/breath	606 ± 51	598 ± 45	0.74
Minute ventilation, L/min	6.8 ± 0.4	7.6 ± 0.4	<0.01
End-tidal carbon dioxide, %	5.6 ± 0.1	5.2 ± 0.1	<0.01
Oxygen saturation ($\text{S}{\text{p}}_{{\text{O}}_2}$)	99 ± 0.3	99 ± 0.2	0.63
Hypoxic ventilatory response, L/min/%	−0.64 ± 0.08	−0.85 ± 0.09	0.03

Data are reported as means ± SE from n = 17 (11 male/6 female) participants. The effect of intermittent hypoxia (IH) (pre-IH, post-IH) was assessed using a one-way repeated measures ANOVA.
