public static java.lang.String HKMetadataKeyVO2MaxValue()
```
    [@constant] HKMetadataKeyVO2MaxValue
    Represents a VO2Max value that can be associated with, for example, Cardio Fitness Events
    This key should be used to store an HKQuantity with a unit of `ml/kg·min`
  - HKMetadataKeyLowCardioFitnessEventThreshold
```
public static java.lang.String HKMetadataKeyLowCardioFitnessEventThreshold()
```
    [@constant] HKMetadataKeyLowCardioFitnessEventThreshold
    Can be used to store a snapshot of the threshold used to classify VO2Max values as "low"
    This key should be used to store an HKQuantity, with a unit of `ml/kg·min`, representing the low fitness threshold.
  - HKMetadataKeyDateOfEarliestDataUsedForEstimate
```
public static java.lang.String HKMetadataKeyDateOfEarliestDataUsedForEstimate()
```
    [@constant] HKMetadataKeyDateOfEarliestDataUsedForEstimate
    Represents how far back an estimation algorithm incorporated data from.
    The expected value is an NSDate indicating the earliest date of data used to produce an estimated value for an HKSample.
  - HKMetadataKeyAlgorithmVersion
```
public static java.lang.String HKMetadataKeyAlgorithmVersion()
```
    [@constant] HKMetadataKeyAlgorithmVersion
    The version of the algorithm used to generate the sample.
    The key for an NSNumber containing an NSInteger indicating the version of the algorithm used to generate the sample.
