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 = 153 x (MHR/RHR)
What is absolute VO2Max?
Aerobic Capacity (or VO2 Max) Your Maximum Oxygen Consumption (eg, VO2Max or MaxVO2) can be expressed as an absolute value or as a value relative to your body weight Absolute VO2 is simply the maximal rate of oxygen uptake you reached at the end of the test and is expressed in liters per minute (L/min)
Is absolute VO2 the same as VO2 max?
Absolute versus Relative VO In its simplest form, VO2 is the difference between oxygen inspired and oxygen expired in a unit of time (eg, one minute), and VO2max would be the greatest quantity the body is able to consume
What does 170 VO2 max mean?
If you’ve ever done true Tabata at 170% VO2 max, you know that you are doing well if you complete the eight 20-second repeats On a bike, your legs are burning, you’re sweating and you feel like you’re riding through mud It’s that challenging to do You might get to the eight repeats
How do you calculate RER?
The Respiratory Exchange Ratio (RER) is defined as VCO2 produced divided by VO2 consumed (where V is Volume)
What is VO2 max calculator?
Your VO2 max is the maximum amount of oxygen your body can utilise during exercise VO2 max is often used to test the cardiovascular fitness or aerobic endurance of an athlete, before, during, and at the end of a cycle of training
Why is VO2 max measured in mL/kg min?
VO2 max is measured in milliliters of oxygen used in one minute per kilogram of body weight (mL/kg/min) It is based on the premise that the more oxygen an athlete consumes during high-level exercise, the more the body will generate adenosine triphosphate (ATP) energy in cells
How do you calculate absolute uncertainty?
Relative uncertainty is relative uncertainty as a percentage = δx x × 100 To find the absolute uncertainty if we know the relative uncertainty, absolute uncertainty = relative uncertainty 100 × measured value
What is the formula for absolute change?
Subtract the beginning value from the ending value to calculate the absolute change In the example, subtract 1,000 from 1,100, which equals 100 This is the absolute change, which means the student population grew by 100 students during the year
How do you find the absolute difference?
Absolute difference is essentially the distance between 2 numbers on a line, calculated using the formula x – y The absolute difference is the value between two numbers, this is always an absolute value which is a non-negative number
What is the VO2 Reserve?
Your VO2 max is how much oxygen your body uses during maximal effort; your VO2 reserve is a figure that’s used as the midpoint in calculations to derive your desired exercise intensity — in terms of oxygen uptake — from your VO2 max
How do you calculate VO2?
This was calculated using the following equation: 50%VO2 = (VO2max – 35mL/kg/min) • 50% + 35mL/kg/min Once 50%VO2 was calculated, exercise intensity was determined using a speed of 3 mph (804m/min) with varying degrees of incline, using the following equation: 50%VO2 = (
Is Garmin VO2max accurate?
The results from these runners found that Garmin’s VO2 max estimation was 95% correct and the error was less than 35ml/kg/min The results are reasonably accurate granting most sub maximal testing has an error of 10-15% So the bottom line is keep the tracking of your workout and user information accurate
Is VO2max of 50 good?
The average non-trained male achieves a VO2 max of roughly 30 to 40 mL/kg/min A good VO2 max score for a 30-year-old man is 50-55 mL/kg/min, while a good a score for a 30-year-old woman is 45-50 mL/kg/min
What is a good VO2max for my age?
Maximal oxygen uptake norms for men (ml/kg/min) Age (years) rating 18-25 26-35 excellent > 60 > 56 good 52-60 49-56 above average 47-51 43-48
How do you calculate RER in VO2max?
RESPIRATORY EXCHANGE RATIO RESPIRATORY EXCHANGE RATIO RER = VCO2/VO2 Oxidation of a molecule of Carbohydrate Now that I know how to calculate R, what does this mean to me? You can determine what fuel is being used for energy production R Excess Post-Exercise Oxygen Consumption Due to: Maximal Oxygen Uptake (VO2max)
What is RER in VO2max?
Two other useful values that are determined during a VO2 max test are Lactate Threshold (LT) and Respiratory Exchange Ratio (RER) RER is the ratio of the volume of carbon dioxide you exhale versus the volume of oxygen you consume at a given exercise intensity
How do you calculate RER caloric equivalent?
It is calculated by taking the oxygen consumed (VO2) times the caloric equivalent per liter of oxygen consumed (taken from Table 1) for the RER value obtained For example, using the mixed-diet RER of 082, the amount of energy liberated per liter of oxygen consumed is 4825 kcal (see Table 1)
How do I calculate my VO2 max per mile?
Your VO2 Calculations Multiply 084 by your BMI and subtract the number from your first result to gain a revised total Multiply -841 by your mile time in minutes and subtract the result from the revised total
How do you calculate VO2 max from submaximal?
Use one submaximal HR and one workload Steady-state HR should reach between 130-150 bpm Calculate SM VO2 and METS using ACSM equation (remember… 1MET= 35 ml/kg/min) VO2 (male)= SM VO2 (expressed as METs) x (Hrmax-61)/ (HRsm- 61) VO2 (female)= SM VO2 (expressed at METs) x (Hrmax-72)/ HRsm –72)
