Oxygen utilization efficiency

Oxygen utilization efficiency refers to how effectively your body uses the oxygen you breathe in during physical activity. When you exercise, your muscles need oxygen to produce energy. This efficiency measures how well your body delivers and uses that oxygen for fuel. Higher efficiency means your body can do more work with less oxygen, indicating good cardiovascular health and aerobic fitness. Factors like training, breathing capacity, and overall health influence this efficiency. Improving oxygen utilization can enhance endurance and physical performance, making activities feel easier and reducing fatigue.
