In intensive disciplines, athletes try to increase the stamina of the body and strengthen the respiratory system. To improve performance, athletes go to highland areas to train in conditions of hypoxia (lack of oxygen). For those who can’t change their place of study, breathing restrictors that imitate mountain training come to the rescue.
These are sports accessories equipped with a multi-level respiratory resistance system the air. The design is based on valves that dispense oxygen.
The athlete, putting on an air restrictor, makes it difficult for him to breathe freely during the training, which, according to the manufacturers, should have a positive effect on increasing aerobic endurance.
Manufacturers also declare the following advantages of a training mask:
Popular masks for training are Elevation Training Mask 2. 0 (price around 2100-2700 p.), Phantom Training Mask (2000-3000 p.
), Bas Rutten O2-trainer (3500-5000 R. ). The first two models are stoppers worn on the face and equipped with a valve system. The Bas Rutten simulator consists of a silicone tube clamped between the teeth and several breathing pads.
The skepticism of the accessories in question is associated with a small number of studies.
At the same time, the effectiveness of a real hypoxic training for endurance is not questioned. In highlands, the air becomes thinner, which leads to a decrease in the amount of oxygen in the athlete's blood.
In response to adverse conditions, the body begins to intensively produce myoglobin and hemoglobin, as well as increase the density of capillaries. As a result, with regular training, the athlete gradually improves overall endurance and "digestibility" of oxygen.
However, the training mask is not able to create a rarefied environment for inspiration , it only prevents the free flow of air.
In addition, American scientists found that the respiratory limiter reduces the oxygen consumption of an athlete by only 2%, which is significantly lower than the similar indicators measured during hypoxic training.
Based on the foregoing, it was concluded that masks are not suitable for effective breathing training and increased anaerobic endurance. They can serve only as a means of strengthening the inspiratory muscles.
Healthy athletes with prolonged use of the hypoxic restrictor may feel heart rhythm disturbance, dizziness, nausea, and even faint.
For any negative symptoms, you should immediately stop training, remove the accessory from your face and bring your breathing to normal.
For those who have health problems, it is recommended that they undergo a medical examination before using the restrictor, so as not to aggravate the pathology. The main contraindications to the use of simulators are cardiovascular diseases and problems with the respiratory system.
This type of sports accessory differs from the above. Such masks are not considered as limiters, but filters for inhaled air. Main functions: delay of exhaust gases containing harmful substances (lead, sulfur, nitrogen, benzopyrene, soot, etc.
), as well as protection against pollen and other allergens.
The most popular products of the English company Respro. All respirators of the manufacturer are equipped with replaceable filters, as well as special valves that exhaust exhaled air. In addition, the undoubted advantage of Respro products is a vibrant youth design that complements any sporty look.
Respro can be used as a mask for running in urban environments.
For example, the Techno model (3700-4000 r.) Has a carbon HEPA filter that perfectly copes with plant pollen, as well as with a wide range of pollutants that affect a person in the city (construction dust, exhaust gases, industrial emissions).
In addition to running training, respiratory accessories are perfect for cyclists, motorcyclists and extreme sportsmen to protect from adverse weather conditions.
The advantages also include simplicity of design and interchangeability of elements, which allows to improve the characteristics and appearance of the accessory.
In general, respiratory masks do not significantly impede breathing.
All people using them noted rapid addiction. The disadvantages include the accumulation of condensate under the neoprene pad, as well as the impossibility of quenching thirst "on the go." Have to stop and pull off the mask to drink.
