During a classroom experiment, students were challenged to measure their lung capacity, which is the maximum amount of air the lungs can hold. The teacher explained that this capacity can vary according to body size and the individual's physical condition. Subsequently, a discussion was initiated about athletes and the importance of the respiratory system in sports practice, highlighting how training can influence the improvement of respiratory performance. Considering the human respiratory system, lung capacity, and its relationship with sports practice, discuss how regular training can contribute to increasing lung capacity and what physiological changes may be involved in this process.

Regular training does not influence lung capacity, as it is solely determined by body size and age of the individual.

Regular training, especially aerobic training, can improve lung capacity through increased strength and endurance of respiratory muscles, improvement of gas exchange in the alveoli, increased efficiency of oxygen transport in the blood, and expansion of the lungs and airways.

Lung capacity decreases with regular training, due to the additional stress that physical exercises impose on the respiratory system.

The increase in lung capacity with regular training is a result of the enlargement of the lungs, which become larger due to physical exercise.

Lung capacity increases only in individuals who engage in high-performance sports, such as Olympic athletes, but not in people who engage in moderate exercises.
