Systolic blood pressure (SBP; mmHg), diastolic blood pressure (DBP; mmHg), heart rate (HR; b/m), hemoglobin oxygen saturation (SaO2; %), Lake Louise (score) and Spiegel test (score), at sea level (SL) and at altitude. Values are means ($\overline{X}$)±SE (standard error), and p was obtained from t-test of related samples.
