Cardiovascular endurance is critical in sports as it reflects the capacity of the heart, lungs, and muscles to perform extended physical activity. High cardiovascular endurance improves oxygen delivery to tissues and enhances the ability to sustain prolonged exercise, making it essential for athletes involved in running, cycling, and swimming. It contributes to faster recovery and better overall performance, allowing athletes to train harder and longer without excessive fatigue. Developing cardiovascular endurance through consistent aerobic training can lead to improved performance metrics in competitive settings.
