`MetadataLastModifiedTime`	When the data was last modified (or originally created) by the application, in ISO 8601 format. Is always in UTC.
`MetadataClientRecordID`	Optional client-supplied record unique data identifier associated with this record.
`MetadataClientRecordVersion`	Optional client-supplied version associated with this record.
`MetadataDeviceManufacturer`	Optional client-supplied manufacturer of the device associated with this record.
`MetadataDeviceModel`	Optional client-supplied model of the device associated with this record.
`MetadataDeviceType`	Optional client-supplied manufacturer of the device associated with this record.

`Vo2MillilitersPerMinuteKilogram`	The user's measured VO2 max, in ml/kg/minute.
`MeasurementMethod`	Optional value for the VO2 max score was measured, one of: `"MEASUREMENT_METHOD_COOPER_TEST"` `"MEASUREMENT_METHOD_HEART_RATE_RATIO"` `"MEASUREMENT_METHOD_METABOLIC_CART"` `"MEASUREMENT_METHOD_MULTISTAGE_FITNESS_TEST"` `"MEASUREMENT_METHOD_OTHER"` `"MEASUREMENT_METHOD_ROCKPORT_FITNESS_TEST"`
