Neuromuscular Fatigue during Prolonged Exercise in Hypoxia
CORTICAL VOLUNTARY ACTIVATION TRANSCRANIAL MAGNETIC STIMULATION BRAIN OXYGENATION KNEE EXTENSORS
2018/4/24
Purpose Prolonged cycling exercise performance in normoxia is limited because of both peripheral and central neuromuscular impairments. It has been reported that cerebral perturbations are greater dur...
A Clustered Repeated-Sprint Running Protocol for Team-Sport Athletes Performed in Normobaric Hypoxia
Acceleration altitude football multiple-set
2016/2/23
The present study compared the performance (peak speed, distance, and acceleration) of ten amateur team-sport athletes during a clustered (i.e., multiple sets) repeated-sprint protocol, (4 sets of 4, ...
Increased Hypoxic Dose After Training at Low Altitude with 9h Per Night at 3000m Normobaric Hypoxia
Hypoxia hemoglobin mass live high: train low athletic performance peak oxygen uptake
2016/2/23
This study examined effects of low altitude training and a live-high: train-low protocol (combining both natural and simulated modalities) on haemoglobin mass (Hbmass), maximum oxygen consumption (VO2...
No Additional Benefit of Repeat-Sprint Training in Hypoxia than in Normoxia on Sea-Level Repeat-Sprint Ability
Hypoxic training simulated altitude top-up training team sport
2016/1/9
To assess the impact of ‘top-up’ normoxic or hypoxic repeat-sprint training on sea-level repeat-sprint ability, thirty team sport athletes were randomly split into three groups, which were matched in ...
Methods to Estimate VO2max upon Acute Hypoxia Exposure
AEROBIC CAPACITY ALTITUDE META-REGRESSION ENVIRONMENTAL PHYSIOLOGY
2017/4/20
Introduction: Altitude and an individual’s V˙O2max contribute to a decrease in V˙O2max under hypoxic conditions. The purpose of this study was to update previous reviews with recent research in order ...
Repeated Double-Poling Sprint Training in Hypoxia by Competitive Cross-country Skiers
ALTITUDE TRAINING REPEATED SPRINTS CROSS-COUNTRY SKI PERFORMANCE
2017/4/19
Purpose: Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasod...
High Twin Resemblance for Sensitivity to Hypoxia
ALTITUDE MONOZYGOTIC TWINS EXERCISE ACUTE MOUNTAIN SICKNESS
2017/4/14
Purpose: Physiological responses to hypoxia vary between individuals, and genetic factors are conceivably involved. Using a monozygotic twin design, we investigated the role of genetic factors in phys...
No influence of hypoxia on coordination between respiratory and locomotor rhythms during rowing at moderate intensity
Control of breathing locomotor-respiratory coupling neuro-mechanical entrainment
2015/4/3
Besides neuro-mechanical constraints, chemical or metabolic
stimuli have also been proposed to interfere with the coordination between respiratory and locomotor rhythms. In the light of
the confli...
The Effects of Hypobaric Hypoxia on Erythropoiesis, Maximal Oxygen Uptake and Energy Cost of Exercise Under Normoxia in Elite Biathletes
Altitude training erythropoiesis aerobic capacity biathlon
2015/5/25
The aim of the present study was to evaluate the effects of 3 weeks altitude training according to the HiHiLo (live high-base train high-interval train low) procedure as described by Chapman et al. (1...
Influence of Acute Normobaric Hypoxia on Physiological Variables and Lactate Turn Point Determination in Trained Men
Hypoxia threshold determination performance heart rate spiroergometry
2015/5/25
The goal of this study is to evaluate the response of physiological variables to acute normobaric hypoxia compared to normoxia and its influence on the lactate turn point determination according to th...
Shuttle-Run Sprint Training in Hypoxia for Youth Elite Soccer Players: A Pilot Study
Altitude training football high intensity training repeated sprint ability Yo-Yo test
2015/5/25
The purposes of the present study were to investigate if a) shuttle-run sprint training performed in a normobaric hypoxia chamber of limited size (4.75x2.25m) is feasible, in terms of producing the sa...
Hypoxic Training: Effect on Mitochondrial Function and Aerobic Performance in Hypoxia
