Oxygen consumption3/2/2023 ![]() ![]() VO2 max = 483 / Test completion time (minutes) + 3. Generally, VO2max declines with age (about 2 per year after age 30) and males typically have a greater oxygen consumption value than females. The subject can run and/or walk but the scope of the test is for the subject to cover the distance as fast as they can. A stopwatch must be used to record the exact time the distance is covered in. This VO2 max test requires an appropriate running location with a measured out distance of exactly 1.5 miles (2414 meters). Measuring the content of hemoglobin in the blood and the percentage. Almost all oxygen in the blood is bound to hemoglobin molecules in the red blood cells. The calculation of the arterial and venous oxygen concentration of the blood is a straightforward process. VO2 max (women) = 65.81 - 0.1847 x Heart rate at test completion VO2 max based on 1.5 Mile Run / Walk Test Determination of the oxygen consumption of the peripheral tissues is more complex. The bigger the body size of an animal, the higher the body mass, the higher the total oxygen consumption for the animal. VO2 max (men) = 111.33 - 0.42 x Heart rate at test completion The oxygen consumption measurements were made on two animals of different body masses which are 7.8496g and 18.2584g. When the 3 minutes pass, the subject must wait for 5 seconds then take their pulse for 15 seconds, then multiply the value by 4 to obtain the heart rate in beats per minute. The subject should step to the beat for 3 minutes. Male subjects should set the metronome at 96 beats per minute whilst female subjects should set it at 88 beats per minute.ĭuring the test, for each beat of the metronome, one step of the sequence should be performed. The following sequence should be followed during the test “left leg up, right leg up, left leg down, right leg down and repeat” and should be preceded by light stretching and practice. ![]() This VO2 max test requires a step that is 16.25 inches from ground level, a stopwatch and a metronome. VO2 max = 132.853 - 0.0769 x Weight in lbs - 0.3877 x Age in years + 6.315 x (0 if Female, 1 if Male) - 3.2649 x Test completion time in minutes - 0.1565 x Heart rate at test completion VO2 max based on Three Minute Step Test At the end of the test, the subject must take their pulse for 10 seconds (then multiply by 6 to retrieve the heart rate in beats per minute. The subject must not run but walk as fast as they can. By using a stopwatch, the subject mut record how long it takes them to walk the measured 1 mile distance. This is also known as the Rockport Fitness Walking Test (RFWT) and the subject must find an appropriate walking location and measure out a distance of 1 mile (1609 meters). Where MHR = 208 – (0.7 x Age) VO2 max based on One Mile Walk Test VO2 max = 15.3 x MHR / (Number of heart beats in 20 seconds x 3) MitoXpress Xtra - Oxygen Consumption Assay (HS Method) is a highly flexible 96- or 384-well fluorescence plate reader-based approach, for the direct, real-time analysis of cellular respiration and mitochondrial function. This is the most simple estimation that only requires the subject’s age and number of hearts beats during 20 seconds. Formulas VO2 max based on Resting Heart Rate ![]()
