Do athletic students have better lung capacity than who are not athletic?

Yes, athletic students generally have better lung capacity than their non-athletic peers. This is because regular physical activity, especially endurance-based activities like running, swimming, and cycling, strengthens the respiratory muscles and increases the efficiency of gas exchange in the lungs. This leads to a higher maximal oxygen uptake (VO2 max), a key indicator of lung capacity and overall cardiovascular fitness. However, it's important to note that this is a general trend and individual variations exist. Factors like genetics, overall health, and the intensity and type of athletic training also play a role.
