Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Cardiorespiratory effects of high altitude exposure

Cardiologia Hungarica
At high altitude, the partial pressure of oxygen in the air is lower than at sea level. During acclimatization, the body adapts to this condition through respiratory, circulatory, renal, and hematological processes.

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.

Non‐invasive assessment of integrated cardiorespiratory network dynamics after physiological stress in humans

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to develop a non‐invasive method for visualizing the cardiorespiratory network under baseline conditions and following isolated or combined exposure to hypoxia, exercise, and sleep deprivation. Twenty‐two healthy participants underwent assessments at rest and after normobaric hypoxia (FIO2${{F}_{{\mathrm{I ...

Mechanisms of haemoglobin mass expansion following heat stress

The Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Augmenting erythropoiesis using recombinant human erythropoietin at sea level blunts the high altitude induced increase in erythropoiesis

The Journal of Physiology, EarlyView.
Abstract figure legend Pharmacologically augmenting erythropoiesis with rEPO at sea level blunts the high altitude induced erythropoiesis. Abstract Erythropoiesis increases with high altitude (HA) acclimatization. Recombinant human erythropoietin (rEPO) induces erythropoiesis.
