## What are the units for VO2 max?

VO2 max is measured in milliliters of oxygen consumed in one minute, per kilogram of body weight (mL/kg/min). It’s not the same thing as heart rate, though it can be just as effective, if not more so, to measure and track your fitness progress.

## What are the units for oxygen consumption?

The primary unit of oxygen uptake is liters of oxygen per minute (L/min), and, in absolute terms, is a direct function of body size. However, as a measure of work capacity, it is usually normalized to body mass, and in its most familiar form is expressed as milliliters per kilogram per minute (mL/kg/min).

**How much does weight affect VO2 max?**

The researchers do further analysis to show that relative VO2max is actually inversely proportional to fat mass — that is, the more body fat you have, the lower your relative VO2max. In fact, fat mass is a better predictor of relative VO2max than exercise performance (how far/fast you go in the VO2max test)!

### Is VO2 max proportional to weight?

The researchers do further analysis to show that relative VO2-max is actually inversely proportional to fat mass – that is, the more body fat you have, the lower your relative VO2-max. In fact, fat mass is a better predictor of relative VO2-max than exercise performance (how far/fast you go in the VO2-max test)!

### How is VO2 max calculated?

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)

**How do you calculate your VO2 max?**

The VO2 max runners calculator will help you become an aware sportsman. Use it to meet your maximal aerobic capacity….The formulas are:

- percent max = 0.8 + 0.1894393 * exp(-0.012778 * time) + 0.2989558 * exo(-0.1932605 * time)
- VO2 = -4.60 + 0.182258 * velocity + 0.000104 * velocity²
- VO2 MAX = VO2 / percent max.

#### How do you calculate oxygen tank consumption?

The calculations are based on Boyle’s law that states that pressure and the volume of a given amount of a confined gas are inversely proportional (P * V = k). k is the tank constant in PSI-1 liters-1. R is the Safe Residual Pressure in PSI, typically 200 PSI….Oxygen Tank Duration.

Name (Dimensions) | Tank Constant |

H (9″ x 52″) | 3.14 |

#### Does BMI affect VO2max?

Increase in the BMI affects the physical fitness and causes decrease in the VO2 max. There is a negative association between BMI and VO2 max. Measuring VO2 max by the NASA/Johnson space central physical activity rating (PA-R) scale is useful in knowing physical fitness of individuals in large scale studies.

**Does weight training improve VO2max?**

Although not all studies have demonstrated significant increases in VO2max following resistance training, the results of this study showed that eight weeks of resistance training were sufficient to result in a significant improvement in VO2max.

## Does your VO2max go up if you lose weight?

Despite the significant weight loss, VO2max increased significantly (P < 0.001) from entry (19.2 +/- 3.0 mL/kg/min) to completion of 10 weeks (22.4 +/- 5.8 mL/kg/min).
