running watches heart rate monitor image
dapo0130
I am going to start interval training (running) and need a watch which keeps track of the time. So I need it to go after 2 mins and then after 20seconds and so on.. I would like it if it had a heart rate monitor too and kept track of what my heart rate was at each interval so I can keep them.. What's the cheapest one that is relatvely good.
Answer
You don't really need a heart monitor.
Long before monitors were invented we just used our heart rate as taken by feeling your neck, if you are going to run again when your heart rate is below a certain level.
As far as a watch you can get a Timex ironman it is reasonably priced and will give you a count down mode for intervals.
I have used them for many years and they last for several years before replacing.

Answer
When your heart pumps, it sends a surge of blood through your body. And, these pulses cause your arteries to expand and contract as the blood surges through. The wrist is a good place to take a heart rate measurement, because the arteries running through it have a definite pulse with each heart beat (that's why they measure your pulse at your wrist).
With each surge of blood, the electrical conductivity of your wrist changes slightly. Or, maybe the capacitance you exhibit between a pair of electrodes changes. But, the electronic circuits in the watch detect these changes in electrical characteristics and count them over time. This is then extrapolated out over a minute and the resulting signal causes a certain number to be displayed on the screen. This is your heart rate.
