Type Property

vo2Max

A quantity sample that measures the maximal oxygen consumption during incremental exercise.

Declaration

static let vo2Max: HKQuantityTypeIdentifier

VO2max is often used as an indicator of health.

These samples use volume/(mass * time) units (described in HKUnit), measured in ml/(kg * min). They measure discrete values (described in HKStatisticsQuery).
