Limits1, 2, 3: Heart rate limits for target zones 1, 2 and 3.
MAX: Together with a heart rate reading indicates the highest heart rate.
MAX %: Together with a heart rate reading indicates what percentage your current heart rate is of your maximum heart rate.
OPTIONS: Indicates the Options mode.
OwnCal: Calculates energy expenditure during exercise in kilocalories. 1 kilocalorie (kcal) = 1000 calories (cal). You can follow how much energy you lose by exercising in one exercise session or in a day, week or even a year. The OwnCal can be used as a dose measure of exercise Ex. in nutrition planning. OwnCal calorie calculation starts when your heart rate reaches 90 bpm or is above 60% of your maximum heart rate, whichever is smaller. These limits are set to count only exercise calories. The higher the heart rate, the faster the energy expenditure.
OwnCal is individually calibrated by your preset weight, maximal oxygen uptake (VO2max) and maximum heart rate (HRmax). The most accurate OwnCal is received by entering your clinically measured (in maximal treadmill or bicycle stress test)
VO2max and HRmax into the wrist receiver. Energy expenditure
measurement is most accurate in continuous activities such as cycling and running.
OwnINDEX: Result of Polar Fitness Test and comparable score with maximal oxygen uptake (VO2max in ml/kg/min).
RecoHr, heart-rate-based
recovery: You set the heart rate, which will end your recovery calculation. In the File mode you will see the drop in your heart rate and the recovery duration. RecoTime,
