What are the 4 things you need to calculate VO2 max?
Calculating VO2 Max
- VO2 max = maximum milliliters of oxygen consumed in 1 minute / body weight in kilograms.
- VO2 = (milliliters of air inhaled per minute)(percentage of oxygen in the air inhaled) / (milliliters of air exhaled per minute)(percentage of oxygen in the air exhaled)
- VO2 max = 15.3 x (MHR/RHR)
What 4 factors influence an individual’s VO2 max?
There are many factors that can influence VO2max, e.g. heredity, training, age, gender, and body composition. Generally, VO2max declines with age (about 2% per year after age 30) and males typically have a greater oxygen consumption value than females.
What is the criteria for reaching VO2 max?
The classical criterion for VO2max is achievement of a plateau in VO2 despite an increase in work rate. A RER above a certain level, a high level of blood lactic acid, and age-adjusted estimates of HRmax are also used, especially in subjects who failed to achieve a plateau [8].
What makes a VO2 max test qualify as a Max?
VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. The more oxygen a person can use during high level exercise, the more energy a person can produce.
What is the formula for VO2?
VO2 Formula and Calculation The VO2 formula for absolute VO2 is: VO2 (mL/min) = (HR x SV) x a-vO2. “HR” stands for heart rate in beats/min and “SV” for stroke volume, or the amount of blood the heart pumps in each beat.
What are the physiological determinants of VO2 max?
Terms in this set (5)
- RESPIRATION. – Ventilation (rate of depth/breathing) – Haemoglobin to oxygen affinity.
- CENTRAL CIRCULATION. – Cardiac output (HR and stroke volume)
- PERIPHERAL CIRCULATION. – Blood flow (decrease in inactive tissues and increase in contracting tissues)
- METABOLISM.
What physiological variables determine VO2 max?
What is the difference between “maximal” and “peak” oxygen consumption? Maximal oxygen consumption is the single highest oxygen consumption elicited during graded exercise to exhaustion.
What are the four criteria used to assess whether a person has reached their Vo2 max following the Bruce treadmill protocol?
The criterion used to assess V̇O2max included a respiratory exchange ratio ≥ 1.10, a heart rate in excess of 90% of age predicted heart rate maximum (220-age), and identification of a plateau (<150 ml x min−1 increase) in V̇O2max despite a further increase in velocity.
Which four factors indicate that v̇O2max has been reached?
Which four factors indicate that V̇O2max has been reached? Carbon dioxide plateau, oxygen consumption plateau, exhaustion, heart rate ≥ 220. RER ≥ 1.15, heart rate ≥ 220, lactate buildup, oxygen consumption plateau. RER ≤ 1.15, heart rate max, volitional exhaustion, carbon dioxide plateau.
What does a VO2 max test tell you?
A VO2 max test is a maximal exercise test performed on a treadmill or bike while connected to a machine capable of analyzing your expired air. Your test provides data on how much oxygen you use as you exercise and determines the maximal oxygen you can consume during exercise.
What are the four criteria for achieving VO2 max?
The four criteria used for achieving VO2 max are plateau in oxygen consumption as workload increases, a respiratory exchange ratio (RER) of greater than 1.05 to 1.15, a blood lactate level from 8 to 10 mm/L, and a heart rate that is within 10 to 12 beats of the age predicted maximum heart rate.
What is the vovo2 Max chart for women?

What is the origin of the ̇VO2 max concept?
Hill and colleagues 12), in the 1920s, conducted a series of experiments, using Douglas bags to collect expired air samples during maximal exercise, which leads to the ̇VO2 max concept.
What is the VO2 max of an elite athlete?
In sports where endurance is an important component in performance, such as cycling, rowing, cross-country skiing, swimming and running, world-class athletes typically have high VO2 max. Elite male runners can consume up to 85 mL/kg/min, and female elite runners can consume about 77 mL/kg/min 28).
