# physicalEffort

A quantity sample type that measures the estimated amount of energy being used to perform a task excluding other factors such as temperature, altitude, or heart rate.

## Declaration

```swift
static let physicalEffort: HKQuantityTypeIdentifier
```

## Discussion

Discussion These samples use power in Metabolic Equivalent of Task (METs) units (described in HKUnit) and measure discrete values (described in HKQuantityAggregationStyle). Physical effort is estimated and recorded automatically by Apple Watch.
