Our multi-level resistance system reduces air flow through our patented (PAT.8.590.533 B2)"Resistance Training Device" flux valve system. Training Mask promotes increased lung capacity by forcing you to inhale fuller deeper breaths.altitude training mask When your body adapts to the resistance your lungs will be trained to take deeper breaths and use oxygen more efficiently. A short explanation of how this works is simple. When you breathe against resistance the lining in the lungs essentially stretches out allowing the alveoli’s surface area to become "stretched" thus in return allows for more blood flow to the alveoli for more (oxygen transportation). When you increase "surface area" you could increase red blood cell count that could carry more oxygen out to the extremities.While using Training Mask 2.0 the conditioning of your lungs significantly increases along with endurance and diaphragm strength.altitude training mask 2.0 Training Mask 2.0 will benefit your respiratory system as your overall cardio and endurance will improve with continued use.Self guided running sessions at a simulated altitude of 2,710m (15% oxygen). Walk on the treadmills with a rucksack in preparation for trekking at altitude or run at your own pace for accelerated fitness gains. We utilise state of the art treadmills in our advanced altitude chamber and monitor your progress every step of the way. There are many breathing devices and respiratory trainers used by hundreds of elite athletes for sports altitude training equipment performance and by other users for health and fitness. Some of these devices are invented to increase strength of the respiratory muscles. Numerous clinical trials have found that these devices can increase endurance and VO2max (maximum oxygen absorption during most intensive exercise), improve lung function tests (VEF, PEF, FVC, and VEmax), lower heart rate for the same load, and overall improve your quality of life and lead to other beneficial health effects.
