What use does a Heart Rate Monitor have if you have a Powermeter?

There is only one occasion I would consider use of HRM has priority over a power meter (or indeed no monitor at all and simply using perceived exertion), i.e. your doctor or cardiologist has ...

Daily commuter - stamina got worse after saddle height adjustment

A change of saddle height won't change your stamina. 'Stamina' is a crude term that reflects many processes within the body which contribute to powering the bike forward. At a very basic level, we ...

What use does a Heart Rate Monitor have if you have a Powermeter?

You can tell when you are knackered. Power indicates your actual output. With a baseline of previous power and HR data, you can establish a model for what you should be able to do. When your ...

Finding my physiologically relevant maximum heart rate

The 220 - age (or any age based formula) is a myth that works well enough for roughly 60% of the population and puts the other 40% wrong. That it persists to this day with such ready access to HR ...

What use does a Heart Rate Monitor have if you have a Powermeter?

Using a Heart Rate Monitor (and a cadence and speedometer, but no power meter), how can I remain in Heart Rate Zone 3?

It's most likely that your bike computer is using your age to determine a maximum heart rate and then determining some zones based on that. This is common practice amongst devices that use HRM data, ...

What target heart rate or power do people use when commuting by bike

I would claim, without data so just thinking about my experience with the world, that most commuters are not targeting heart rate or power, they are just trying to get to work. Some want to get there ...

Why don't professional cyclists use the Maffetone method?

Because it does not work. First: As discussed in comments, the assumption that maximum aerobic heart rate can be calculated as 180 - age is wrong and heart rate is not very good indicator of power ...

How to approach zone practice if heart rate zones are completely inaccurate

Max HR isn't a particularly useful metric. Not only is it particularly difficult to measure/estimate, but it can't be used to accurately define training zones, as there are large variations between ...
