Combining Hypoxic Methods for Peak Performance
New methods and devices for pursuing performance enhancement through altitude training were developed in Scandinavia and the USA in the early 1990s. At present, several forms of hypoxic trainingExpand

Operation Everest III (Comex '97): modifications of cardiac function secondary to altitude-induced hypoxia. An echocardiographic and Doppler study.
During Operation Everest III (Comex '97), to assess the consequences of altitude-induced hypoxia, eight volunteers were decompressed in a hypobaric chamber, with a decompression profile simulatingExpand

Operation Everest III (Comex'97): the effect of simulated sever hypobaric hypoxia on lipid peroxidation and antioxidant defence systems in human blood at rest and after maximal exercise.
Eight subjects were placed in a decompression chamber for 31 days at pressures from sea level (SL) to 8848 m altitude equivalent. Whole blood lipid peroxidation (LP) was increased at 6000 m by a meanExpand

Interchangeability between heart rate and photoplethysmography variabilities during sympathetic stimulations.
Photoplethysmography variability (PPGV) is currently considered to be a good surrogate to heart rate variability (HRV) measurements using the time between two pulse waves instead of RR intervals.Expand

Diurnal variations of acute mountain sickness, colour vision, and plasma cortisol and ACTH at high altitude.
Time dependence of colour vision in the green/red axis, signs of acute mountain sickness (AMS), and plasma cortisol and ACTH concentrations were studied in eight sea-level male natives exposed 79 hExpand

Blunting effect of hypoxia on the proliferation and differentiation of human primary and rat L6 myoblasts is not counteracted by Epo
Objectives:  The aim of this study was to evaluate whether hypoxia and/or erythropoietin would be able to modulate proliferation/differentiation processes of rat and human myoblasts.

Adrenergic status of humans during prolonged exposure to the altitude of 6,542 m.
Plasma norepinephrine (NE) concentration increases with altitude exposure while maximal heart rate (HR) and chronotropic response to isoproterenol (IP) are blunted. Downregulation of cardiacExpand

Energy balance at high altitude of 6,542 m.
Weight loss due to malnutrition and possibly intestinal malabsorption is a well-known phenomenon in high-altitude climbers. Up to approximately 5,000 m, energy balance may be attained and intestinalExpand

Swimmers can train in hypoxia at sea level through voluntary hypoventilation
This study used an innovative technique of pulse oximetry to investigate whether swimmers can train under hypoxic conditions through voluntary hypoventilation (VH). Ten trained subjects performed aExpand

Hypoxia-induced differential modulation of adenosinergic and muscarinic receptors in rat heart.
To better understand the decreased chronotropic response to catecholamines in chronic hypoxia, we compared the inhibitory pathways regulating adenylate cyclase in rats exposed for 30 days toExpand
