Aerobic capacity can be improved through training by engaging in regular endurance activities. Consistently performing exercises like running, swimming, or cycling enhances cardiovascular efficiency, allowing the heart and lungs to deliver oxygen more effectively to muscles. Structured training programs that include interval training, tempo workouts, and long-distance runs can progressively increase aerobic capacity. Gradually increasing intensity and duration helps the body adapt, promoting better stamina and performance. Improvements in aerobic capacity contribute to overall health, enabling individuals to undertake daily activities with greater ease and energy.
