Influence of Hyperoxic-Supplemented High-Intensity Interval Training on Hemotological and Muscle Mitochondrial Adaptations in Trained Cyclists
Hyperoxia (HYPER) increases O2carrying capacity resulting in a higher O2delivery to the working muscles during exercise. Several lines of evidence indicate that lactate metabolism, power output, and endurance are improved by HYPER compared to normoxia (NORM). Since HYPER enables a...
Inadequate cerebral oxygen delivery and central fatigue during strenuous exercise
Under resting conditions, the brain is protected against hypoxia because cerebral blood flow increases when the arterial oxygen tension becomes low. However, during strenuous exercise, hyperventilation lowers the arterial carbon dioxide tension and blunts the increase in cerebral blood flow,...
The effect of inhaling concentrated oxygen on performance during repeated anaerobic exercises
The objective of the pilot study was to test the effect of inhaling 99.5% oxygen on recovery. The source of concentrated oxygen was O-PUR (Oxyfit). Research subjects completed two thirty-second Wingate tests at an interval of ten minutes, and in...
Changes in reaction time when using oxygen inhalation during simple visual matching tasks
This study attempted to identify the effect of inhalation of highly concentrated oxygen on reaction time during simple visual matching tasks. Nine right-handed male graduate students (23.0+/-1.4 years) participated in the study. Two subsets of simple visual matching tasks with...
Breathing in pure oxygen is 'as effective as Viagra'
Breathing pure oxygen for 90 minutes a day can be as effective as Viagra for treating impotence - with none of the side-effects and potentially longer-lasting results, new research shows. Men who had the treatment had an average 50 per...
