BACKGROUND We investigated the effects of chronic hypobaric hypoxic acclimatization, performed over the course of a 72-day self-supported Everest expedition, on ventilatory chemosensitivity, arterial saturation, and tissue oxygenation adaptation along with total hemoglobin mass (tHb-mass) in nine experienced climbers (age 37±6 years, [Formula: see text] 55±7 mL·kg(-1)·min(-1)). METHODS Exerci...

Diving acclimatization refers to a reduced susceptibility to acute decompression sickness (DCS) in individuals undergoing repeated compression-decompression cycles. We demonstrated in a previous study that the mechanism responsible for this acclimatization is similar to that of stress preconditioning. In this study, we investigated the protective effect of prior DCS preconditioning on the sever...

We tested the hypothesis that the decline in muscle sympathetic activity during and after 8 h of poikilocapnic hypoxia (Hx) was associated with a greater sympathetic baroreflex-mediated responsiveness. In 10 healthy men and women (n=2), we measured beat-to-beat blood pressure (Portapres), carotid artery distension (ultrasonography), heart period, and muscle sympathetic nerve activity (SNA; micr...
