Intermittent hypoxic–hyperoxic training on cognitive performance in geriatric patients

IntroductionIntermittent hypoxic–hyperoxic training (IHHT) may complement a multimodal training intervention (MTI) for improving cognitive function and exercise tolerance in geriatric patients. MethodsThirty-four patients (64–92 years) participated in this randomized controlled trial. Before and after the 5- to 7-week intervention period (MTI 1 IHHT vs. MTI 1 ambient air), cognitive func- tion was assessed by the Dementia-Detection Test (DemTect) and the Sunderland Clock-Drawing Test (CDT), and…

Adaptations following an intermittent hypoxia-hyperoxia training in coronary artery disease patients: a controlled study

Background: Repeated exposure to intermittent normobaric hypoxia improves exercise tolerance in cardiac patients. Little is known on the effects of intermittent normobaric hypoxia-hyperoxia exposure in coronary artery disease (CAD) patients (New York Heart Association II-III). Hypothesis: IHHT improves exercise tolerance, cardiometabolic profile, and quality of life in CAD patients. Methods: The study design was a nonrandomized, controlled, before-and-after trial. Forty-six CAD patients volunteered to take…

Intermittent Hypoxia–Hyperoxia Conditioning Improves Cardiorespiratory Fitness in Older Comorbid Cardiac Outpatients Without Hematological Changes: A Randomized Controlled Trial

Aim: To compare a program based on intermittent hypoxia-hyperoxia training (IHHT) consisting of breathing hypoxic-hyperoxic gas mixtures while resting to a standard exercise-based rehabilitation program with respect to cardiorespiratory fitness (CRF) in older, comorbid cardiac outpatients. Materials and methods: Thirty-two cardiac patients with comorbidities were randomly allocated to IHHT and control (CTRL) groups. IHHT completed a 5-week program of exposure to hypoxia-hyperoxia while resting, CTRL…

Intermittent Systemic Hypoxic-Hyperoxic Training for Myocardial Protection in Patients Undergoing Coronary Artery Bypass Surgery: First Results From a Single-Centre, Randomised Controlled Trial

Background: Although remote ischaemic preconditioning (RIP) provides protection against myocardial ischaemia and reperfusion injury during cardiac surgery, it is not widely used. Systemic intermittent hypoxic-hyperoxic training (IHHT) may be a suitable alternative. Methods: This is a prospective, single-centre, randomised controlled trial. 127 patients with ischaemic heart disease and indication for coronary artery bypass graft (CABG) surgery from the Cardiology Clinic IM Sechenov First Moscow State…
