Regular cardiovascular exercise positively impacts lung capacity by improving the efficiency of the respiratory system. Such exercises increase the strength of the diaphragm and intercostal muscles, enhancing their ability to expand and contract the lungs. This results in greater oxygen uptake and carbon dioxide expulsion during physical activities. Over time, regular aerobic activity can lead to adaptations that increase lung volume and overall respiratory health. Improved lung function translates to better endurance and performance in both athletic pursuits and daily life activities, making cardiovascular exercise essential for fitness.
