Suunto - Polar interval timers

Customer question:
Please can you tell me, which of the male-specific chest-strap type heart rate monitors that you supply have an integrated ‘interval timer’ preferably with separate warm-up but not essential? Do any have 2 seperate inteval timers e.g. 40sec High, 60sec Low, and seperate 20sec High and 90sec Low?
heart rate monitor uk says:
The Suunto T3C heart rate monitor - Suunto T4C heart rate monitor and Suunto T6C heart rate monitor have
1 x WARM UP TIMER
followed by
TIMER 1
followed by
TIMER 2
then repeat timer 1 and timer 2
During these stages of interval timing, the heart rate zone does NOT change - it only has 1 x active HR zone
The Polar RS200 has 3 x timers.
Tmr1 Tmr2 and Tmr3
Each timer has it’s OWN HR zone
You can run just T1 on repeat - or - T1 then T2 and repeat or - T1, T2 and T3 then repeat…
You can start heart rate monitoring by pressing START once, WARM UP manually… then strat session proper by pressing START again, this then starts T1-T2-T3 process….
The Polar RS400 and Polar RS800 have even more flexibility - adding RECOVERY times between intervals
An example of a Polar RS400 heart rate monitor Polar RS800 interval session would be
10 mins warm up between 100 - 130 bpm
Then 5 x 3 min intervals between 140 - 155 bpm with a second recovery interval
Then 20 mins steady at 130 - 140 bpm
Then recovery down to 90 bpm.

Max Heart Rate? how is it calculated
08/11/2007 by Tris.
How do YOU work out theoretical maxHR - maximum heart rate??
I have read so many different methods - but which one’s really work??
We use the one published by Ken McLaren of KinEli publishing. Ken’s method takes in to consideration RESTING heart rate as well as age and sex.
