This is widely believed but scientifically unproven. The understanding of the significance of awareness of heart rate to workout performance is ongoing. Basically, tracking heart rate shows what is already known, that improving cardiac performance will improve resting heart rate. The stated purpose of doing so is to increase self-esteem. For the same reasons there are large mirrors installed at most gyms.
> Also, accurately measuring your times, and seeing even few seconds improvement since the last week's training helps keep you motivated.
A $5 stopwatch is accurate to hundredths of seconds.
> There are many reasons to use such accessories, other than "stroking vanity".
This is an appeal to common sense, aka the fallacy of axiomatic thinking, or unsupported assertion. Claims which can be asserted without evidence may also be dismissed without evidence.
Having a device to help you stay in the right Zone is very valuable for effective training.
Large mirrors are in gyms to help with form when using equipment.
I'm not sure what you expect to accomplish by using obscure and invented health industry terminology absent from medical science and citing this kind of evidence with a three hour long podcast that I'm simply not going to entertain.
Regardless, you have constructed a new straw man argument. My point was far less complicated, which is that expensive and complex technological devices as sport accessories distract from the natural incentive of improving fitness and are unnecessary and functionally duplicated with an inexpensive stopwatch. The natural incentive for improved health is traded for the incentive for being entertained by absurdly detailed metrics without advantage to the fundamental goal of improving fitness.
Unnecessary reliance on accessories will synthetically make it more difficult to do the same activity if the accessories are removed, for whatever the reason they happen to not be available, stolen, lost, broken, whatever. Exercise is its own reward, and there is little reason to replace that incentive with the need to be entertained by detailed metrics of past events.
> Your statements are bizarre and arrogant. It feels like debating with an edgy teenager.
More ad hominem attacks.
Please do not be concerned about the opinions of others. Please follow you heart and do what makes you happy. I strongly insist that you do.
"by using obscure and invented health industry terminology absent from medical science"
"Zone 2 HR" is just an alias for 65%-75% of your max heart rate with Zone 3 being 80%-85% and so on ... very simple, and max HR % is used across the medical profession (along with VO2 Max) [1][2][3][4] ... I could go on and on.
These "zones" are defined by the point at which metabolic processes change. After ~zone 2, you burn more glycogen and engage fast twitch muscles, and this affects cellular respiration differently in terms of performance pay-off. At ~zone 3 the metabolic processes and chemical balances change again, and so on [5]
You VERY evidently have so little idea about what you're actually talking about, at this point I consider it a troll and I won't bother continuing.
