# cyclingFunctionalThresholdPower

A quantity sample type that measures the estimated maximum average power sustained while riding a bike for 60 minutes.

## Declaration

```swift
static let cyclingFunctionalThresholdPower: HKQuantityTypeIdentifier
```

## Discussion

Discussion Cycling Functional Threshold Power (FTP) is an estimate of the maximum average power you can sustain for 60 minutes while riding a bike. These samples use power units (described in HKUnit) and measure discrete values (described in HKQuantityAggregationStyle). During cycling workouts, the system automatically records estimated FTP samples on Apple Watch.
