completely out of breath at low HR. need your help please

Are you sure it's 88-90% max HR and not actually your 100%? The formula of 218-Age isn't appropriate for everyone. It's just meant as a standard approximation and may not be correct for you, personally. You might be an anomaly.

But if you're sure there's something wrong, maybe you should get an ECG.

It could be Ebola.

Yes, I'm sure it's 88-90% not more.

I got my HRmax tested in a lab a few months ago and I got 182. And during today's interval workout it was about 157-162.

Btw I'm 21 if it can help.

Did the OP died?

I think he is dead.

I ran some 1000m repeats today and I couldn't get my HR over 88-90%.

Then I ran a few 400's all out and it didn't get any higher, which means I was pretty slower than I should be.

Assuming I couldn't push any harder it seems real weird. I just don't get it, it felt like I couldn't carry oxygen to my lungs.

Over the last weeks I've felt that during each workout, it feels like my lungs can't keep up with the rest of my body...

has anyone ever experienced something similar? what could it be due to? what are your thoughts?

thanks

it's ebola bro, go get quarantined

At this point, since you're feeling bad/unusual in workouts and you can't seem to max your HR out, I would go to the doctor if it continues.

OP, you have two separate issues here.

1. What is your heart rate normally when you do this workout? Do you know? If not, it's not unusual to not get your heart rate very high during short intervals.

2. You're slower and feel like you can't get enough oxygen. That could be overtraining, low level flu, or something more dangerous. I often have a similar reaction when I'm overtraining, haven't recovered sufficiently from the previous day's workout, or have a slight flu. If it lasts more than a couple of weeks, you need to see a doctor to rule out anything more serious. Oh, and if you're female, it could be anemia (low iron related). It happens to guys too, but it's more common in women due to menses.

Thanks for the advice. If it lingers, I'll definitely go to the doctor.

I'm a dude. So, I hope it's not related to iron deficiency or any other form of anemia.

Any other thoughts?

are your legs feeling like lead? Many years ago, I began losing my breath on very slow runs, and my legs especially quads felt like lead. I had a blood test and got diagnosd with a rare form of Leukemia. regardless, at least get a blood test.

Wow, leukemia! Well it's quite different for me: legs feel OK and I don't have any trouble running at lower pace.

It shouldn't be that bad but I'll probably get my blood checked though.

First suspect is iron - actual ventilation (as in raw oxygen perfusion) is rarely an issue even for the unfit. The difference is how that oxygen is used at the molecular level, and obviously the first step here is haemoglobin.

Next is RBC count (hematocrit or PCV). A variety of disorders can cause your RBC count to drop.

Next is assuming you have enough RBCs with functional haemoglobin to deliver O2 to the cells. Aerobic ATP production is very complex and relies on many sequential steps, with O2 as the terminal electron acceptor. A variety of things can go wrong here.

If you are delivering the O2 and using it correctly to produce ATP, you may have problems with clearing or utilising the byproducts of aerobic respiration - CO2 and lactate respectively.

If you don't feel run down generally, the problem is likely to be easily treatable as it affects only performance and a sedentary person wouldn't notice. Most likely a vitamin or iron deficiency. If you DO feel run down generally, the list is long. In any case, see a GP.

Exercise induced asthma?

I had EIA when first beginning to run. The wheezing is unmistakeable. You're less concerned with hitting a PR as you are with remaining upright.

A good guess though, I can only comment because I have had it.

What were your recoveries?

Never heard of that. I googled it and well it might be a real possibility! Thanks all for your help.

One more thing, the day (or even 2 days) after a race or a hard workout I still have much trouble breathing and my chest is slightly painful. Like today, I went out for an easy run and my lungs still felt sore from yesterday's session...

Anyway, I made an appointment with my GP for next Friday. I definitely need a full check up.

2:30min jog, but I already felt miserable during the first 1000m (after a 2 miles warmup)

Then things went from bad to worse.

could be pneumonia or COPD

Good call Once and Future.

I've been diagnosed with EIA by my doctor. I got an inhaler and now running hard in the cold is fine (or at least much better). thanks all.
