What their individual target zones are for different training objectives (% HRmax) What their HR is in rest (HRrest), and if there is any sign of over- training Continuously if they do what they should do on different training days If they are in a good shape or not, depending on their HR recovery after 1 min (may vary between 40 and 60 bpm) If they made progress, depending on their HR during a fitness test... HR monitoring is ‘the best way’ to tell referees:

The transmitter belt detects the heart’s electric signal Signals are sent to the wrist receiver one beat at the time The wrist receiver converts the signal into a beats per minute reading The wrist receiver can also analyse, interpret and store heart rate information...
