Cardiorespiratory Effects of One-Legged High-Intensity Interval Training in Normoxia and Hypoxia:A Pilot Study
Local muscle training altitude training exercise physiology
2016/7/7
A higher-than-average maximal oxygen consumption (VO2max), is closely associated with decreased morbidity and mortality and improved quality of life and acts as a marker of cardiorespiratory fitness. ...
Similar Hemoglobin Mass Response in Hypobaric and Normobaric Hypoxia in Athletes
ALTITUDE TRAINING LIVE HIGH-TRAIN LOW SIMULATED ALTITUDE PERFORMANCE ENDURANCE ATHLETES INDIVIDUAL RESPONSE
2017/4/13
Purpose: To compare hemoglobin mass (Hbmass) changes during an 18-d live high–train low (LHTL) altitude training camp in normobaric hypoxia (NH) and hypobaric hypoxia (HH).
Methods: Twenty-eight well...
Cycling Time Trial Is More Altered in Hypobaric than Normobaric Hypoxia
NORMOBARIC HYPOXIA HYPOBARIC HYPOXIA PERFORMANCE EXERCISE
2017/4/13
Purpose: Slight physiological differences between acute exposure in normobaric hypoxia (NH) and hypobaric hypoxia (HH) have been reported. Taken together, these differences suggest different physiolog...
Modeling Intermittent Cycling Performance in Hypoxia Using the Critical Power Concept
ALTITUDE WORK-BALANCE HIGH-INTENSITY FATIGUE
2017/4/13
Purpose: This study investigated the efficacy of an intermittent critical power (CP) model, termed the “work-balance” (W′BAL) model, during high-intensity exercise in hypoxia (HYPO).
Methods: Eleven ...
Cycling Exercise Training Alleviates Hypoxia-Impaired Erythrocyte Rheology
EXERCISE HYPOXIA ERYTHROCYTE HEMORHEOLOGY
2017/4/13
Purpose: Physical exercise or hypoxic exposure influences hemorheology and acid–base homeostasis. Band 3 protein in erythrocytes modulates cells’ rheological properties and anion transport ability. Th...
Hypoxia Inducible Factor-1α (HIF-1 α) and its Role in Tumour Progression to Malignancy
HIF HIF-1α Hypoxia Malignancy Cancer Cancer Therapy
2015/7/28
Hypoxia is a condition in which an area of the body or a tissue is deprived of sufficient supply of oxygen. The lack of nutrients in a hypoxic tissue generally causes apoptosis but some cells are able...
Enhanced Performance after Repeated Sprint Training in Hypoxia: False or Reality?
Repeated Sprint Training Repeated Sprint Training
2017/4/20
Anyone working with highly trained athletes will be doubtful toward any intervention that increases exercise performance by 55% after six training sessions, as recently reported by Faiss et al. (1). T...
Assessing Objective Measures of Sleep Quality in Hypoxia Research
Hypoxia Research Objective
2017/4/19
We read with interest the recently published work from Hoshikawa et al. (3) in which the authors perform a rigorous evaluation of various sleep measures, first during five nights’ stay in normoxia, an...
Effects of Five Nights under Normobaric Hypoxia on Sleep Quality
HYPOXIA QUALITY OF SLEEP ADAPTATION RESPIRATORY DISTURBANCES
2017/4/19
Purpose: The purpose of this study was to evaluate the effects of five nights’ sleep under normobaric hypoxia on ventilatory acclimatization and sleep quality.
Methods: Seven men initially slept for ...
Pronounced Muscle Deoxygenation During Supramaximal Exercise Under Simulated Hypoxia in Sprint Athletes
NIRcws muscle deoxygenation hypoxic 30s Wingate test athletes
2015/4/17
The purpose of this study was to determine whether acute hypoxia alters the deoxygenation level in vastus lateralis muscle during a 30 s Wingate test, and to compare the muscle deoxygenation level bet...
A Hypoxia Imaging of Rodent Xenografts with 18F-Fluoromisonidazole: Comparison of Dynamic and Static PET Imaging
Tumor Hypoxia Dynamic image Compartmental Modeling 18F-FMISO PET
2013/1/29
Purpose: To generate parametric images of tumor hypoxia in a tumor-bearing rat model using voxel-based compartmental analysis of dynamic fluorine-18 labeled misonidazole (18F-FMISO) microPET? images, ...
This study addresses the question of whether repeated acute exposure to hyperbaric oxygen, such as encountered in O2 diving, affects the peripheral oxygen chemosensors. Groups of nondivers, active O2 ...
Effects of Acute Hypoxia on Body Substrate Utilisation During Progressively Increasing Work Rate Exercise Tests
Exercise tests respiratory quotient substrate utilisation
2009/6/24
Respiratory quotient (RQ) was used to assess the effectiveness of exercise interventions in shifting substrate utilisation. The body's RQ can be estimated non-invasively from the ratio of CO2 producti...
