Aerobic capacity, commonly measured by VO2 max, relates directly to overall fitness as it reflects the body’s ability to efficiently utilize oxygen during prolonged exercise. A higher aerobic capacity indicates better cardiovascular health and endurance, allowing individuals to perform physically demanding activities for extended periods. Improving aerobic capacity enhances overall exercise performance, contributes to weight management, and lowers the risk of chronic diseases. Thus, focusing on cardiovascular training and activities that boost aerobic capacity is crucial for anyone looking to enhance their overall fitness levels.
