Polar sport zones

Polar sport zones introduce a new level of effectiveness in heart rate-based training. Training is divided
into five sport zones based on percentages of maximum heart rate. With sport zones, you can easily select
and monitor training intensities.
Target zone
MAXIMUM
HARD
MODERATE
LIGHT
VERY LIGHT
HR = Maximum heart rate (220-age). Example: 30 years old, 220–30=190 bpm.
max
Running in sport zone 1 is done at a very low intensity. The main training principle is that your
performance level improves during recovery after training, not only during training. You can accelerate
your recovery process with very light intensity training.
Sport zone 2 is for endurance training, an essential part of any training program. Running sessions in this
zone are easy andaerobic. Long-duration training in this light zone results in effective energy expenditure.
Progress will require persistence.
