Aerobic exercise positively influences lung capacity by enhancing the efficiency of the respiratory system. Regular aerobic activities, such as running or cycling, promote better oxygen uptake and improve overall lung function. During these exercises, the body demands more oxygen, leading to increased breathing rates and the development of lower respiratory muscles. Over time, this adaptation increases the lungs' ability to exchange gases, which can enhance endurance levels and overall cardiovascular health. Improved lung capacity further supports better performance across a range of physical activities.
