Intermittent hypoxic training (IHT) refers to the discontinuous use of normobaric or hypobaric hypoxia, in an attempt to reproduce some of the key features of altitude acclimatization, with the ultimate goal to improve sea-level athletic performance. In general, IHT can be divided into two different strategies: (1) providing hypoxia at rest with the primary goal being to stimulate altitude accl...

The aim of the present study was to evaluate the efficacy of intermittent hypoxic training (IHT) with 95 % of lactate threshold workload (WRLT) on aerobic capacity and endurance performance in well-trained cyclists. Twenty male elite cyclists, randomly divided into a hypoxia (H) group (n=10; age 22 ± 2.7years; VO2max 67.8 ± 2.5 ml·kg(-1)·min(-1); body height (BH) 1.78 ± 0.05 m; body mass (BM) 6...

OBJECTIVE To investigate the effects of physiological ischaemia training on the quantity and activity of endothelial progenitor cells in rabbits with intermittent myocardial ischaemia. METHODS A reversible coronary artery water balloon occluder (5.0 mm inner diameter) was placed around the proximal left ventricular branch and intermittent myocardial ischaemia was induced by deflation and infl...

the aim of this study was to investigate the effect of a change in the sequence of concurrent endurance and strength training on aerobic power and body composition of active men. 30 men (mean age 25.8 ± 3.50 years) with endurance and strength training history were divided into these groups: endurance training before strength training (es, n=10), strength training before endurance training (se, ...

The purpose of this study was to assess, the effects of continuous and intermittent exercise training on lactate kinetic parameters and maximal aerobic speed (MAS) using field tests. Twenty-four male sport students were equally divided into continuous (CT) and intermittent (IT) physically trained groups. Another six participants acted as non-trained controls (CG). The trained participants pract...

OBJECTIVE Strenuous physical activity, such as military training, is known to demand a high degree of physical performance and to cause overuse injuries. However, the exact relation between injury incidence and physical fitness level and the influence of military training on measures of functional performance, such as intermittent endurance capacity and maximal jump performance, are not fully d...

This study was designed to (1) investigate the effects of acute short-duration intermittent hypoxia on musclemRNAand microRNAexpression levels; and (2) clarify the mechanisms by which short-duration intermittent hypoxia improves endurance capacity. Experiment-1: Male mice were subjected to either acute 1-h hypoxia (12% O2), acute short-duration intermittent hypoxia (12% O2for 15 min, room air f...
