Breathing rate:- The number of times a person breaths in one minute is called breathing rate.

The average breathing rate in an adult human being at rest is 15 to 18 times per minute.

During heavy physical exercise, the breathing rate of an adult human being can increase upto 25 per minute (or even more).

☆ Women breathe slightly faster than men.

☆ Children breathe about 20 to 30 times per minute.

☆ An athlete breathe faster and deeper then usual even after finishing a race this is because during the race, the leg muscles of an athlete have produced extra energy by doing anaerobic respiration (without using oxygen). By breathing faster and deeper, the athlete is giving back oxygen to the muscles which it could not give earlier at the time of running (due to lack of oxygen at that time).
