PATHOLOGY

Detailed explanation-1: -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 litres of air will pass through an athlete’s lungs.

Detailed explanation-2: -At complete rest, the typical adult male exchanges approximately 0.5 l (500; 400 ml for female) of air per breath (tidal volume) at a rate of 12 times per minute, resulting in a minute ventilation rate of about 6 l of air per minute.

Detailed explanation-3: -A normal breathing rate for an adult at rest is 8 to 16 breaths per minute. For an infant, a normal rate is up to 44 breaths per minute.
