How does one determine maximum pulse rate? I do workouts where I'm constantly at 160-170 bpm for 15 minutes and my lungs aren't burning nor am I about to collapse (aged mid-30s, if that matters)

Here are a few simple field tests you can perform to measure maximum running heart rate.

Note that wearable fitness trackers that use wrist optical heart rate sensors often don't give accurate readings on such tests so it's best to add a chest heart rate sensor.

carefully...

"Since HRmax varies by individual, the most accurate way of measuring any single person's HRmax is via a cardiac stress test. In this test, a person is subjected to controlled physiologic stress (generally by treadmill or bicycle ergometer) while being monitored by an electrocardiogram (ECG). The intensity of exercise is periodically increased until certain changes in heart function are detected on the ECG monitor, at which point the subject is directed to stop. Typical duration of the test ranges ten to twenty minutes."

I think it might be dangerous for some people to seek out max heart rate without a doctor present.

CDC says 220 beats per minute, minus your age in years:

If you need an accurate number, it should be measured manually. Some sports clinics can do this; measuring true VO2 Max, as well as actual max heart rate.
I've heard that estimate before (80% would be ~150bpm for me). But then the physiological effects described by the GP don't seem right as I need to go much higher to feel anything like "my lungs burning" (maybe 190+?)
I’m 35 and this year I had actual measured hr of 198 so that formula is bs for trained individuals
It might sound stupid but work as hard as you can and note your maximum.

I’m 180bpm-ish as a 45 year old male, I get that trying to cycle uphill as hard as I can and can sustain it for some minutes.

They say the equation is 220bpm minus your age, so you should be able to go a bit higher.

Age based equations for maximum heart rate are mostly bullshit. More recent research has shown that there is much less decline in maximum heart rate with age, at least for athletes with a decent level of fitness. And there is a huge amount of natural variation between individuals which is often more significant than age effects.

Maximum heart rate is also sport dependent. For an equivalent level of fitness, maximum cycling HR is often about 10bpm lower than maximum running HR. This is because running engages more muscles and doesn't restrict breathing as much.

Yeah, not saying it’s a perfect rule, just making the point that the parent’s 160-170bpm is lower than what I’d expect his max to be, using the rule of thumb a lot of people know.

(And for what it’s worth, my max heart rate is the same when cycling or running, within a small margin of error. I’ve never thought to ask anyone if it’s the same for them - I will do now!)

> just making the point that the parent’s 160-170bpm is lower than what I’d expect his max to be

Just want to clarify, I mentioned 160-170 bpm as a regular workout I do where I do not feel anywhere near max (I have seen my heart rate get above 190 while running).

I was replying to this:

> For 80-85% of maximum pulse rate...

> If your lungs are burning and you're about to collapse after 30 seconds of activity the intensity is about right.

And saying that going at 160-170 (above 80-85% according to rule of thumb) for a prolonged period of time, I feel none of those symptoms.

For my whole life i sustain 195-200 for 1h. Im 40+ now and run a 10k a day (45mins). Even a very slow 10k (1h) i never go below 170 after the first 5 minutes.
