Having a good lung capacity is important because you'll need it when it comes to sports and running.
Total lung capacity refers to the maximum amount of air a personâs lungs can hold, about four to six liters (4000 to 6000 cm3) for the average human. Only a third of this capacity is used during normal activity, but this fraction increases during strenuous activity when the body requires more oxygen. On average, males have a 20-25% higher capacity than females, and tall individuals have a greater capacity than short people. The human lungs enable respiration.
