WebPoint: maximal oxygen uptake is limited by a central nervous system governor. A classic teaching predicts that maximal exercise is limited by the capacity of the heart to pump blood to the systemic circulation since the fully dilated skeletal muscle arterial bed can alone accommodate more than the maximal cardiac output (Q) ( [1] [1], [25] [2]). Web7 feb. 2024 · To determine your VO2 max if your resting heart rate is 60 bpm and you're 30 years old: Calculate your maximum heart rate by multiplying your age by 0.7 and deducting it from 208, which equals 187 bpm. Divide your maximum heart rate (187 bpm) by your resting heart rate (60 bpm) and multiply by 15.3. That's all.
