RUNNING POWER FROM THE WRIST
Running power is a great complement to heart rate monitoring – it helps you monitor the external load of your running.
Power responds to changes in intensity faster than your heart rate, which is why Running Power is a great guiding metric in
interval and hill sessions. You can also use it to maintain a steady effort level during your run, for example in a race.
The calculation is done with Polar's proprietary algorithm, and it is based on your GPS and barometer data. Your weight
also affects the calculation, so make sure its up-to-date.
Running power and muscle load
Polar uses running power to calculate Muscle load, one parameter of
Training Load
Pro. Running causes musculoskeletal
stress, and Muscle load tells you how much your muscles and joints were strained during your training session. It shows
the amount of mechanical work (kJ) that you produced during your running sessions (and cycling sessions if you're using a
cycling power meter). Muscle load helps you quantify your training load in high-intensity running training sessions, such as
short intervals, sprints and hill sessions, when your heart rate doesn't have enough time to react to the changes in the
intensity.
How running power is shown on your watch
Running power is automatically calculated for your running sessions done with running type sport profiles with GPS
available.
Choose the power data you want to view during your sessions by customizing your training views in the Flow web service
sport profile settings.
During your run you can view the following data:
