The relationship between oxygen consumption (VO2), oxygen delivery (DO2), and the extraction ratio
The relationship between oxygen consumption (VO2), oxygen delivery (DO2), and the extraction ratio
(A) An inverse relationship exists between oxygen delivery (DO2) and the extraction raio (ER), with no correlation between oxygen consumption (VO2) and the ER. (B) An improved ability to extract oxygen during exercise exists at all levels of DO2.
