The air of gym is clean the fitness before the room

When people chooses gym, the problem such as the level of the admirable, coach of the discretion that what often notice above all is gymnastical check price, equipment, quality of airy of gym of very few however attend to.
Current, choose relatively airtight edifice in a lot of gym of big city in, some still is in underground perhaps undertakes training in half basement, uses ventilated device is central air conditioning more. So the body building that has collective in this kind of environment, can your inspiratory air quality be what kind of?
In course of study of fitness of institute of Asian sports government senior management is talked on altar, china of Er of Huo Ni Wei) the expert Chai Cimei of the ministry of product of indoor air quality of limited company, undertook to this special subject makes a speech.
From the expert enumerated a variety of data make clear, indoor pollution is 8 times outdoor. Below the normal case that does not make any motion, minutely breath controls human body 18 times, engulf pure oxygen about 200 milliliter, at the same time eduction carbon dioxide 280 milliliter. If 50 people are in in gym, minutely need engulf pure oxygen about 10 thousand milliliter adds up to 10 litres) , at the same time 14 thousand milliliter adds up to eduction carbon dioxide 14 litres) . So, if this 50 people wait for 60 minutes in gym, need engulf pure oxygen 600 litres, want eduction at the same time 840 litres of carbon dioxide. When motion, it is especially when carry momentum is bigger, the carbon dioxide of the oxygen of human body engulf and eduction is more.
When high above in the sky enrages medium carbon dioxide chroma to exceed 8 ％ , the person can appear the god is exhausted, lack of power, be discouraged, angry the unwell symptom such as thick, asthma. The expert discovers through determining, the carbon dioxide chroma of individual gym already amounted to 15 ％ above. Change rises and fall when moving as a result of the person, mix carbon dioxide but agitate of inspiratory grain content must writhe up and down, the air in whole gym can become very extremely thick.
Chai Cimei points out, a few establishment inside gym become airy possibly also to pollute a source, for instance: Plywood of balata carpet, density board, man-made and furniture sofa. Especially new clothes is repaired, the gymnastical place that just opened business, bury next formaldehyde very easily to transcend the hidden trouble such as pollution of mark, air, the person that go against fitness undertakes oxygen moves having.
Motion having oxygen wants fresh air, if there are good ventilated equipment and convection device in gym, will bring about waste gas to circulate ceaselessly in limited space, still can catch epidemic disease, for the person that take exercise to those who have oxygen campaign is being done in gym, without advantage.
In the meantime, the sweat fluid that human body body expresses and microbial wait for corresponding also increase, right now if air exchange is scant, the bacterium in air, virus, pathogen and carbon dioxide pile up, cause the disease such as sore throat, tracheitis, flu easily.
