Fact: The average human during rest processes 11,000 liters of air every day. The image above shows in real scale this fact. Making some basic calculations the average human breathes ±8-11 litres of air per minute. An athlete can breathe more than 150 litres per minute and elite male athlete can breathe even up to 240 litres per minute, so in an hour of hard training 14,400 liters of air will pass through an athlete’s lungs.
We have to make sure that each liter of air is pollutants free such as PMs, CO, NOx, SOx and O3 and especially for athletes that breathe more than 20,000 liters of air per day and the breathings are more deep and can reach deeper regions inside their lungs.
