Can asked you a serious question about heartbeat. Below is my heart rate chart this morning for an approximate 12km run...

View attachment 220512
Is it ok to tax my heart to maximum for 77% of the run duration (or about 38mins out of the 50mins) ?

Or will I damage my heart in the long term?

Nope won't damage . I have been riding at zone 5 forever with no issue

I am sure Brother sam Leong rides at Zone 7 or 8 with ease

But don't just listen to a 4 board vaccinated cuck. Go get a CT angiogram to make sure all your coronaries are patent.

Any idiot can write anything on the internet

3 reasons for sudden cardiac arrest in athletes:

1. unstable coronary cholesterol plaque which shears off during stress and cuts off blood supply to the heart. Can be detected with CT angiogram and stented by a trained interventional cardiologist

2. sudden arrhythmia leading to arrest - simply suay. Born that way. When it's time to go it's time to go

3. Vaccination with mRNA vaccine causing spike proteins to attack the heart - you have been brainwashed by misinformed conspiracy theorists and deserve to die anyway

A friend of mine keeled over and died in front of my eyes despite being stented and certified fit to ride.

Postmortem revealed that plaque sheared off from some other part of the body and ended up in the heart stopping blood flow.

If you have to go it's a good way to depart. He didn't even feel it when he hit the ground.

This is not possible. There is something wrong with your settings. It is impossible to sustain 90% to 100% of your max heart rate for such a huge percentage of your exercise routine.

I didn't lie. I normally would run very fast. First 15 to 20mins, I will feel strained and unmotivated but I push myself to Max. And when I cross that time mark, I don't feel any thing , no pain, no strain and motivated, then can sustain all the way

When you are close to your max heart rate you are in oxygen deficit so there is no way you can hold that effort for 77% of your run.

I suspect you have set your max heart rate too low. It is probably 15 to 20 beats higher than what you have set.




When cycling, levels of effort are often categorized into heart rate zones or perceived exertion, similar to the zones in your running chart. These zones help gauge intensity and tailor workouts for specific goals like endurance, speed, or recovery. Below are the typical levels of effort for cycling, described using heart rate zones (based on a percentage of your maximum heart rate, MHR) and perceived exertion:
  • Zone 1: Low Intensity (50-60% of MHR)
    Effort: Very easy, conversational pace. You can talk in full sentences and breathe comfortably.
    Purpose: Recovery rides, warm-ups, or cool-downs. Builds base endurance with minimal strain.
    Example: A leisurely ride where you’re barely breaking a sweat.
  • Zone 2: Weight Control / Endurance (60-70% of MHR)
    Effort: Comfortable but slightly challenging. You can still talk, but you might need to pause for breaths. Breathing is deeper.
    Purpose: Builds aerobic endurance and improves fat burning. Ideal for long, steady rides.
    Example: A moderate-paced ride where you feel you could go for hours.
  • Zone 3: Aerobic / Tempo (70-80% of MHR)
    Effort: Moderately hard. Talking becomes tougher; you can manage short sentences but not long conversations. Breathing is noticeably faster.
    Purpose: Improves aerobic capacity and efficiency. Good for longer efforts at a sustainable but challenging pace.
    Example: A brisk ride where you’re pushing but not sprinting.
  • Zone 4: Anaerobic / Threshold (80-90% of MHR)
    Effort: Hard. Speaking is limited to a few words at a time; you’re focused on breathing and maintaining pace. Legs start to burn.
    Purpose: Increases lactate threshold (the point where your body can’t clear lactate as fast as it’s produced). Great for building speed and power.
    Example: A sustained effort like climbing a steep hill or doing intervals.
  • Zone 5: Maximum (90-100% of MHR)
    Effort: All-out, maximum effort. Talking is impossible; you’re gasping for air, and your legs are screaming. Can only sustain for short bursts.
    Purpose: Boosts VO2 max (maximum oxygen uptake) and anaerobic capacity. Used for sprints or high-intensity intervals.
    Example: A full-on sprint or an intense climb where you’re giving everything you’ve got.

I never change any settings on the watch. So it uses the default 220-age formula to calculate the HR zones. Maybe I should change the formula.

Ah that is the problem. The formula is a guideline but every individual is different.

You can establish your max heart rate by going absolutely flat out for as long as possible ie an all out sprint. I am pretty sure it will be higher than 220 minus your age.

Ok..will try.

One other thing is my sleeping heart rate can go as low 35 to 40 sometimes when I am sleeping. Damn weird. I told the doctor and he said nothing serious.

Nothing wrong with that in fact a low resting heart rate indicates an excellent Vo2max which is a measure of your body's ability to convert oxygen to energy efficiently.

Elite cyclists have resting heart rates as low as 28.

that's not a plaque

it was a good sized embolus from a large vein enough to choke the pulmonary artery
 
The PAP seems to love CECAs so much even though our women and children will be put in grave danger by having so many of such people in S'pore like Indian national Pramender, who molested a 12-year-old girl on 31 March at Jalan Besar Swimming Complex, and tried to pull her into the toilet with him. He was sentenced to only 3 months’ jail.
 
Ruptured plaque = embolus?
Anything floating in the blood with the potential to occlude a vessel is an embolus

Cholesterol embolus from a ruptured plaque

Nitrogen embolus in a diver

And in your friend’s case a venous thrombus in a large leg vein dislodging to form an embolus into the heart

I’d even wager your friend is Caucasian. They are prone to this sort of thing

Yes Ang moh through and through. They’re also prone to hip problems many have hip replacement before 65.

However they seem to be less prone to type 2 diabetes.
 
drink your mother's cunt juice
You got to laugh at those doctors who went for jabs and got turbo cancer and sudden death.

These swindlers don’t even know how to heal themselves lol

And some of you still think these swindlers can save you? Lol
