Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Elevated carotid body tonic activity contributes to ventilatory acclimatization and de‐acclimatization to high altitude at rest and during exercise

The Journal of Physiology, EarlyView.
Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).

Acid base status of prevalent peritoneal dialysis patients

Bulletin de la Dialyse à Domicile, 2018
Acid-base status of patients on peritoneal dialysis is influenced by multiple factors. Metabolic acidosis is a common feature of chronic renal failure and dialysis treatment provides alkali in the dialysate in order to maintain a normal acid-base balance.

The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...
