How Apple Watch to know or to calculate the intensity of my workouts?

Hi all

I used my Apple Watch now since some time in combination with the application of activity for different types of workouts such as running etc and I am curious about the watch or the activity app knows the intensity of a workout as a race.

The rate watch or app works just like a similar race or does it somehow make a difference if a race is more or less "hard"?

I am interested in this because I think that there is a difference if you go on a relaxed atmosphere, 10km run, or if you for example one very hard works on a mountain. Can watch it / app don't know if you use for example up the Hill?

I was recently on a very relaxed ran about 10 km with my girlfriend. After such a race I feel very exhausted, but the activity app still said I burned some calories. Now another day I went to a really hard and fast race up a hill which was a lot however shorter, only about 6km. In this case the activity app said I burned fewer calories than on race relaxed and I really can't believe that run if I work very hard compared to a relaxed atmosphere.

That's why I wanted to know how it actually works and hope someone can answer me.

Thank you and best regards,

Thomas

Hi Thomas

When follow you an activity using the application of the training session and specify a type of activity, your watch uses the most appropriate sensors and data sources to estimate the outcome of this workout.

For example, when you save a run in the open air:

  • If you also take your iPhone along (with compatible Bluetooth and location Services), your watch can access the GPS of the iPhone data when estimating the PACE and distance.
  • If you do not take your iPhone along, the watch relies on data from the accelerometer in the estimate of the PACE and distance.
  • Data from the heart rate sensor is used during the estimation of the Active Calories, including calculations which are adapted to different activity types.

Calibrate your watch helps improve the accuracy of the different estimates made by the activity and workout app app. More information and instructions for calibration of your watch are available via the link below.

Estimates of the results will also depend on your personal information. To verify that this is correct - and update over time:

  • On your iPhone, in the application of the watch, go to: My Watch tab > health > edit - tap and adjust the settings, then press on in fact.
