To assess how altitude training impacts force-velocity-power (F-V-P) profiling and muscular power anaerobic capacity in elite badminton players reference to intra- inter-individual sex-based variability. Following a quasi-experimental design, 14 (6 females, 8 males) from the French national singles doubles teams performed 3-week 'living high-training high' camp at natural (2320 m). F-V-P profile Wingate test were assessed Pre- Post-intervention, using ANOVA repeated measures conventional...
ABSTRACT Carbon monoxide (CO) rebreathing is frequently used to determine hemoglobin mass (Hb ) during hypoxic or heat training and high‐altitude research. Accurate reliable carboxyhemoglobin (HbCO) determination crucial for Hb measurements. The aim was therefore explore the stability of HbCO interchangeability two Radiometer analyzers in . Twelve subjects performed a CO test. Five capillary blood samples were taken before after test either analyzed immediately on site (three tubes, Day 1,...
Abstract Current guidelines for prolonged altitude exposure suggest levels ranging from 2000 to 2500 m optimize an increase in total hemoglobin mass (Hbmass). However, natural low locations (<2000 m) remain popular, highlighting the interest investigate any possible benefit of camps endurance athletes. Ten elite racewalkers (4 women and 6 men) underwent a 4‐week “live high‐train high” (LHTH) camp at 1720 (P I O 2 = 121 mmHg; 20.1°C; 67% relative humidity [RH]), followed by 3‐week tapering...
Acute apnea is known to induce decreases in oxyhemoglobin desaturation (SpO2) and increases erythropoietin concentration ([EPO]). This study examined the potential of an training program erythropoiesis increase hematological parameters exercise performance. Twenty-two male subjects were randomly divided into control group. The group performed a 6-wk consisting daily series five maximal static apneas. Before after training, visited lab on 3 test days perform 1) ramp incremental measuring...
Heart rate during prolonged breath-holding until the point of loss consciousness has not previously been published. The recordings show that blackout was preceded by a period persistent alterations in R-R intervals, whereby an ectopic beat followed every normal heartbeat. Explanations for this deviating heart pattern could be either premature atrial contractions or ventricular following beat, i.e., bigeminy, which have compromised cardiac pumping function and caused/contributed to blackout.
Intense exercise evokes a spleen contraction releasing red blood cells into circulation. The same mechanism is found after acute apnea, increasing hemoglobin concentration ([Hb]) by 2% to 5%. aim of this study was twofold: [1] identify the optimal apnea modalities acutely increase [Hb] and [2] use these examine whether prerace can improve 3-km time trial (TT).In part 1, 11 male subjects performed 12 different protocols based on three modalities: mode, frequency, intensity. Venous samples for...
Repeated-sprint training in hypoxia (RSH) is an effective way of improving physical performance compared with similar normoxia. RSH efficiency relies on severity, but also the oxidative-glycolytic balance determined by both sprint duration and exercise-to-rest ratio. This study investigated effect 2 types sessions during a classic altitude camp world-class female rugby sevens players.Sixteen players performed 5 cycle ergometer (simulated altitude: 3000 m above sea level [asl]) 3-week natural...
With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is increasing importance, where exposure (HA) imposes a blood oxygenation acid–base challenge. A sustained augmented hypoxic ventilatory response protects through acclimatization, but elicits hypocapnia respiratory alkalosis. subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with degree interindividual variability....
Introduction: Acute apnea evokes bradycardia and peripheral vasoconstriction in order to conserve oxygen, which is more pronounced with face immersion. This response contrary the tachycardia increased blood flow muscle tissue related higher oxygen consumption during exercise. The aim of this study was investigate cardiovascular metabolic responses dynamic dry (DRA) immersed (FIA). Methods: Ten female volunteers (17.1 ± 0.6 years old) naive breath-hold-related sports, performed a series seven...
During sustained exposure to high altitude, integrated respiratory and renal acclimatization protects blood oxygenation acid-base homeostasis, respectively. A augmented hypoxic ventilatory response (HVR) with ascent (i.e., acclimatization). However, the HVR elicits hypocapnia alkalosis. subsequent renally-mediated compensatory metabolic acidosis partially returns pH back baseline values, a degree of variability, capacity for full compensation limited approximately 4000-4500m. In convenience...
The increase in heatwaves, a significant consequence of global warming, represents major public health issue and is the main cause death related to hyperthermia. seriousness such exposure extreme ambient temperature lies difficulty general population identify warning signs take appropriate protective measures. This article therefore presents guidelines for prevention, recognition treatment heat-related illnesses, thus arms clinicians healthcare professionals who are on front line protecting...
PURPOSE: Apnea training has recently been proposed as a simple and cheap method to stimulate erythropoietin (EPO) production increase hemoglobin (Hb) concentration hematocrit (Hct). This study aimed investigate both acute chronic effects of apnea on spleen volume hematological values through an 8-week program. METHODS: Thirteen subjects daily performed five static apneas. Before, halfway after the period, maximal breath-holds at laboratory. Baseline for changes in splenic volume, [Hb], Hct,...
Introduction. Intense exercise evokes a spleen contraction releasing red blood cells into the circulation. This improves oxygen transport capacity which is beneficial for performance. The same mechanism found following acute apnea, increasing [Hb] by 2 to 5%. Therefore, aim was examine whether pre-race apnea can improve performance in 3km time trial (TT) through apnea-induced before onset of exercise. Methods . 11 recreationally active subjects performed cycling TTÂ following 10 minute...
