Abstract The compensatory reserve index (CRI), derived from machine learning algorithms from peripherally obtained photoplethysmography signals, provides a non‐invasive assessment of cardiovascular stability, that may be useful clinically. Briefly,

Implementing permissive dehydration (DEH) during short-term heat acclimation (HA) may accelerate adaptations to the heat. However, HA with DEH may augment risk for acute kidney injury (AKI). This study investigated the effect of HA with permissive DE

Female adults have a lower tolerance to central hypovolemia, simulated by tilt testing and lower body negative pressure (LBNP; PMID: 26109186). However, the mechanisms responsible for this observation remain unknown. Previous studies investigated sex

The frequency, intensity, and duration of heat waves are projected to increase in the coming decades. Older adults have impaired heat-dissipating capabilities and are at a greater risk for heat-related morbidity and mortality. Many hospitalizations a

Heatwaves cause disproportionately high mortality rates in those aged ≥ 65 years. While age differences in the cardiovascular responses to heat stress have been investigated, previous studies used a water-perfused suit to elicit heat stress. Theref

Introduction: Every year, ~150,000 patients are treated in the United States with burn-related injuries. Previously, our group has shown that ~75% of burn survivors have a maximal aerobic capacity in the lowest 20th percentile rankings, relative to s

Conditions characterized by muscle wasting such as cachexia and sarcopenia are devastating at the individual level, and they place a profound burden on public health. Evidence suggests that inflammation is likely a mechanistic contributor to the path

Our aim was to determine the effect of repeated sprint exercise in hypoxia on HIF-1 and HIF-1-regulated genes involved in glycolysis, mitochondrial turnover and oxygen transport. We also determined whether genes upregulated by exercise in hypoxia wer
