Non-technical summary The endothelium is a thin layer of cells lining the interior surface of the entire circulatory system. Endothelial progenitor cells (EPCs) have a crucial role in maintaining the integrity of the endothelium, as they are recruite

Patients with mitochondrial myopathies (MM) or myophosphorylase deficiency (McArdle's disease, McA) show impaired capacity for O(2) extraction, low maximal aerobic power, and reduced exercise tolerance. Non-invasive tools are needed to quantify the m

High-altitude Tibetans undergo a pattern of adaptations to chronic hypoxia characterized, among others, by a more efficient aerobic performance compared with acclimatized lowlanders. To test whether such changes may persist upon descent to moderate a

As is well known, with increasing altitude, peak aerobic power (VO2peak) of acclimatized lowlanders undergoes a progressive decrease as a consequence of the decline of barometric pressure and of oxygen partial pressure in inspired air. At any given a

We tested the hypothesis that, in healthy middle-aged subjects (n=11, age 51.0±3.0 years, x ±SD), the effects of exercise training on pulmonary O2 uptake ( $$\dot VO_2$$ ) on- and off-kinetics would appear earlier than those on peak $$ \mathop V\li

Anecdotal observations suggest that the reduction in peak lactate accumulation in blood ([La]b peak) after exhausting exercise, in chronic hypoxia vs. normoxia, may be related to the duration of the exercise protocol, being less pronounced after shor

Recent studies of nonlinear dynamics of the long-term variability of heart rate have identified nontrivial long-range correlations and scale-invariant power-law characteristics (l/f noise) that were remarkably consistent between individuals and were

The dynamics of heartbeat interval time series over large time scales were studied by a modified random walk analysis introduced recently as Detrended Fluctuation Analysis. In this analysis, the intrinsic fractal long-range power-law correlation prop

Muscle ultrastructure and biochemistry in vastus lateralis muscle biopsies and the response to exercise of 8 lowland Tibetans (T) were compared with those of 8 Nepalese lowlanders (N). Blood hemoglobin was lower in T than in N (119 +/- 3 vs. 131 +/-

There are hints that hypoxia exposure may affect the number of circulating endothelial progenitor cells (EPCs) in humans. To test this hypothesis, the concentration of EPCs was determined by flow cytometry in the peripheral blood of 10 young healthy
