The effect of short-term intermittent hypoxic exposure on heart rate variability in a sedentary population.
While the effects of instantaneous, single-bout exposure to hypoxia have been well researched, little is known about the autonomic response during, or as an adaptation to, repeated intermittent hypoxic exposure (IHE) in a sedentary population. Resting heart rate variability (HRV) and exercise capacity was assessed in 16 participants (8 receiving IHE, [Hyp] and 8 receiving a placebo treatment [C...
متن کاملHeart rate variability in exposure to high altitude hypoxia of short duration.
The objective of the presented studies is to attempt an evaluation of heart rate (HR) and heart rate variability (HRV) regulatory mechanisms in the presence of autonomous nervous system (ANS) components in transient exposure to high altitude hypoxia. During 24 hrs including a stay in hypobaria, the participants had their HR continuously recorded using the Holter method. The following parameters...
متن کاملComparison of live high: train low altitude and intermittent hypoxic exposure.
Live High:Train Low (LHTL) altitude training is a popular ergogenic aid amongst athletes. An alternative hypoxia protocol, acute (60-90 min daily) Intermittent Hypoxic Exposure (IHE), has shown potential for improving athletic performance. The aim of this study was to compare directly the effects of LHTL and IHE on the running and blood characteristics of elite triathletes. Changes in total hae...
متن کامل12 days of altitude exposure at 1800 m does not increase resting metabolic rate in elite rowers.
Four elite rowers completed a 12-day altitude training camp living at 1800 m, and training at 1800 m and 915 m, to assess changes in resting metabolic rate (RMR). RMR and body composition were assessed pre- and postcamp. Downward trends in RMR and body composition were observed postaltitude: absolute RMR (percent change: -5.2%), relative RMR (-4.6%), body mass (-1.2%), and fat mass (-4.1%). The...
متن کاملCaloric restriction and intermittent fasting alter spectral measures of heart rate and blood pressure variability in rats.
Dietary restriction (DR) has been shown to increase life span, delay or prevent age-associated diseases, and improve functional and metabolic cardiovascular risk factors in rodents and other species. To investigate the effects of DR on beat-to-beat heart rate and diastolic blood pressure variability (HRV and DPV) in male Sprague-Dawley rats, we implanted telemetric transmitters and animals were...
