- aid: polar:polar-cardio-load-api
  name: Polar Cardio load API
  description: Cardio load is based on training impulse calculation (TRIMP), a commonly accepted and scientifically proven
    method to quantify training load. Your Cardio load value tells you how much strain your training session put on your cardiovascular
    system.  The higher the Cardio load, the more strenuous the training session was for the cardiovascular system.  Cardio
    load is calculated after every workout from your heart rate data and session duration. For more detailed information please
    check [cardio load](https://support.polar.com/e_manuals/unite/polar-unite-user-manual-english/cardio-load.htm).

description: Polar Electro Oy (operating as Polar Global) is a Finnish sports and fitness technology company founded in 1977
  and headquartered in Kempele, Finland. Polar invented the first wireless wearable heart rate monitor — the Sport Tester
  PE 2000 in 1982 — and remains one of the longest-standing brands in consumer heart rate sensing, GPS sports watches, and
  fitness wearables. The Polar device portfolio includes the H10 and H9 chest straps, the Verity Sense and OH1 optical sensors,
  the Polar 360 and Loop fitness bands, and the Vantage, Grit X, Pacer, Ignite, and Unite watch lines, along with a dedicated
  equine sensor line. Developers access Polar data through the Polar AccessLink API for consumer Polar Flow data, the Polar
  TeamPro API for team and player training sessions, and the open-source Polar BLE SDK for iOS and Android applications that
  stream live sensor data over Bluetooth Low Energy.
