The term for the body’s overall physical fitness level is cardiorespiratory fitness. It reflects the efficiency of the heart, lungs, and muscles in supplying oxygen and performing sustained physical activity. High cardiorespiratory fitness is associated with better stamina and endurance during exercise and everyday tasks. It can be measured through various assessments, including VO2 max tests or observing one's performance during aerobic activities. Maintaining or improving cardiorespiratory fitness is crucial for overall health, as it contributes to reducing the risk of chronic diseases and enhancing overall well-being.
