Increased hemoglobin mass and VO2max with 10 h nightly simulated altitude at 3000 m.
PURPOSE To quantify the changes of hemoglobin mass (Hbmass) and maximum oxygen consumption (VO2max) after 22 days training at 1300-1800 m combined with nightly exposure to 3000-m simulated altitude. We hypothesized that with simulated 3000-m altitude, an adequate beneficial dose could be as little as 10 h/24 h. METHODS Fourteen male collegiate runners were equally divided into 2 groups: altit...
متن کاملPre-Altitude Serum Ferritin Levels and Daily Oral Iron Supplement Dose Mediate Iron Parameter and Hemoglobin Mass Responses to Altitude Exposure
PURPOSE To investigate the influence of daily oral iron supplementation on changes in hemoglobin mass (Hbmass) and iron parameters after 2-4 weeks of moderate altitude exposure. METHODS Hematological data collected from 178 athletes (98 males, 80 females) exposed to moderate altitude (1,350-3,000 m) were analysed using linear regression to determine how altitude exposure combined with oral ir...
متن کاملSplit dose versus single bolus gadolinium administration in ecv calculation at 3 tesla cmr
Background Diffuse myocardial fibrosis may be quantified with cardiovascular magnetic resonance (CMR) by calculating extra-cellular volume (ECV) from native and post-contrast T1 values. Previous studies have used either infusion or single bolus contrast administration. In clinical practice however split dose contrast injection is used as part of a stress/rest protocol in stress perfusion studie...
متن کاملHemoglobin mass and intravascular volume kinetics during and after exposure to 3,454-m altitude.
High altitude (HA) exposure facilitates a rapid contraction of plasma volume (PV) and a slower occurring expansion of hemoglobin mass (Hbmass). The kinetics of the Hbmass expansion has never been examined by multiple repeated measurements, and this was our primary study aim. The second aim was to investigate the mechanisms mediating the PV contraction. Nine healthy, normally trained sea-level (...
متن کاملGastric Residual Volume after Split-Dose Bowel Preparation versus Conventional Single-Dose Regimen before Anesthetic Colonoscopy
The aim of this study was to compare gastric residual volume (GRV) in patients given a split-dose versus a conventional single-dose of polyethylene glycol (PEG) preparation before undergoing anesthetic colonoscopy. Methods. In a prospective observational study, we assessed GRV in outpatients undergoing same-day anesthetic gastroscopy and colonoscopy between October 8 and December 30 of 2016. Ou...
