Heart rate, blood pressure, and SpO2 responses to simulated 5000 m hypobaric exposure in healthy male Vietnamese pilots

Physiological Reports, Volume 14, Issue 3, February 2026.
Abstract This study was motivated by the limited high‐altitude physiology data available for Asian military aviators, especially in Vietnam. To characterize acute heart rate (HR), blood pressure (BP), and oxygen saturation (SpO2) responses in healthy Vietnamese pilots during simulated 5000 m hypobaric exposure. Seventy‐five healthy male military pilots

The effect of sex on the isolated and combined α‐ and β‐adrenergic control of blood flow during handgrip in adults at high altitude: An exploratory study

Physiological Reports, Volume 14, Issue 3, February 2026.
Abstract This study examined how sex influences blood flow during exercise at altitude and relative contributions of adrenergic mechanisms. Thirteen participants (8 M/5F) were tested at low and high altitude (days 3–11). Participants performed rhythmic handgrip for 3 min at 25% maximal voluntary contraction during local infusions of saline, propranolol
