VO 2 = Cardiac Output X ( a-v) O 2 difference (ml blood/min ) (ml O 2 /ml blood) . The Fick Equation: Stroke Volume X Heart Rate (ml/beat) (beats/min) VO 2max = The maximal amount of oxygen that the body can utilize. Cardiac Output = Stroke Volume (SV) X Heart Rate (HR) Stroke Volume = The amount of blood in one heart beat – Expressed in milliliters (ml) Heart Rate max = decrease with age? (a-v) O 2 Difference = the difference in oxygen content between the blood leaving the heart (arterial) and the blood returning to the heart (venous). – During exercise, your muscles remove oxygen, thus
