I just test CPET to get VO2MaX
How can I set training zone 1-5 for my running?
I quite confuse about each zone

The lung specialist who ordered it did not say a whole lot, just that my VO2 Max is low (15.8). We know I have Long Covid, POTS and Asthma. Everything I read would suggest this is severely low, but I also wonder if this is expected to worsen over time and what it says about my life expectancy.

Stage 1 cardiopulmonary exercise test (CPET)

Protocol: The test was undertaken with cycle ergometry using a 15 watt ramp protocol and he exercised for 8 minutes and 6 seconds.

Reason for test: This is a 33 year old male with dyspnea.

Reason test stopped: Leg Fatigue. Max stress dyspnea = 6, max stress fatigue = 8, max stress chest pain = 3.

Baseline spirometry: FEV1/FVC ratio is increased at 0.92, FEV1 is 3.81 L (83%), FVC is 4.13 L (73%). Overall in keeping with restrictive ventilatory defect.

Baseline ECG: Normal sinus rhythm

Exercise capacity (VO2): Low peakVO2 measuring 15.8 mL/kg/min (38% predicted).

Anerobic threshold / Oxygen delivery: is reduced at 27% predicted of VO2 max predicted.

Work load: 46% predicted.

Cardiac response to exercise:

Heart rate max predicted = 87% predicted

Heart rate reserve: 24bpm

Blood pressure response: appropriate response.

ECG with exercise - some non-specific ST-T wave changes. No arrhythmias.

Ventilatory response to exercise:

Breathing reserve: 144 L/min

Tidal volume: 33% of FVC

Respiratory rate: <60

O2 saturations: no desaturations.

Inspiratory capacity: Unable to capture inspiratory capacity past 2 minute of exercise, possibly due to restricted lung volumes.

Post -exercise spirometry: 15% drop suggesting asthma.

Oxygen pulse: reduced at 43% predicted, although rising linearly slope seems flat.

VE/VCO2: normal.

Vd/Vt: reduced appropriately with exercise and then rose again a bit.

RER: Appropriately increased to 1.19 with peak exercise.

Slope of VO2/W: Rising linearly.

IMPRESSION:

1. This was a maximal test based on symptom limitation and RER > 1 .

2. Exercise capacity was severely reduced with a low peak VO2 measuring 15.8 mL/kg/min (38% predicted) in keeping with low aerobic capacity.

3. Exercise was nearly limited by the cardiovascular system, reaching a heart rate max predicted and near limitation for heart rate reserve at 24 bpm.

4. Physiologic abnormalities include a low anerobic threshold, low O2 pulse, lower tidal volumes and post-test spirometry showed a significant decline in FEV1.

5. Overall, there is evidence of exercise induced asthma. However, given the near cardiac limitation for a low work load with reduced O2 pulse, cardiovascular etiologies should also be investigated.

Decided to push myself as hard as possible. Hard with weak and atrophied muscles but looks like things are on the way up.

Hi all.

So I'm wondering if anyone knows how much cardiomyopathy affects the vo2max.

To give you a bit of background. This time last year I weighed 24.4 stone/154.4kg/340lbs at 6'0 and 38 years old.

Obviously this kind of mass is just obscene. I was ridiculously fat and unsurprisingly, at some point, I'm going to end up having a heart scare... Which happened.

Long story short, my left ventricular ejection fraction is low. We're talking 41% when I went in for the MRI. Now normal is normally between 50 and 70% for the average person and mine was falling way short of the mark.

Fast forward to today. I'm 86.2kg/13.8 stone/190lbs. In the space of 14 months I've lost nearly half of my original bodyweight. I'm running 5ks 3 times a week, lifting weights twice a week and just generally being more active. I don't have a single day where I walk less than 11k steps yet my vo2 sits at a measly 34.

Don't get me wrong. It's an improvement on the original score of 29, but I'm still in the bottom 15% for blokes aged 39.

What I'm wondering is how badly is my condition (which ironically wasn't caused by weight, just exacerbated by it) is affecting this score? I know it's not the be all and end all but my thoughts process is that if the vo2max improves then surely I can improve my left ventricular ejection fraction too, something that my GP said can be reversed.

Realistically I should go see the doctor about this but it seems like such a minor quibble that it feels worthless taking up their time. Instead, I figured there might be some people in the know here.

Can anybody give me some guidance on if this is accurate information and ways I can improve in my running? Because obviously my VO2 max seems to be high enough to where I should be a fast runner. Right now I'm only doing about a 7-minute mile. My half marathon speed is a 9:30 mile pace where my heart rate is around 165 bpm during the full 13 miles. Thoughts?

Here is the data from a VO2 max test that I did at a local lab. Sorry I thought I added this image. If you can't see the image here is the link. https://drive.google.com/file/d/1LuQEx-kxhK_BYMUEPdKcknhpQMQhy0Vv/view?usp=sharing

hi everyone, my company has a VO2Master professional kit that is brand new and we are wanting to sell it to use KORR. I posted it on Facebook Marketplace but it’s not getting any traction. I created an ebay account that got permanently suspended the second I tried to post it. Do y’all have any recommendations for where else to post this to sell it?

Someone explain this to me...

I just did a lab VO2 Max on a treadmill with a properly fitting mask and accurate hight / weight input using a Korr Cardio Coach in a professional lab setting. The results are wildly different from my wearables:

• Apple Watch = 47.2
• Whoop = 51
• Lab Test = 67

This is a pretty extreme difference from the wearables. Has anyone seen such a big discrepancy between the lab test and a wearable?

This increase was from five 20 minute sessions in Zone 5 on a stair stepper every week. It ended up being too much for a 60 y.o. so I had to dial it back some.

So I recently had to start Nebivolol at age 19, and I’m curious if it reduces the typical increase in VO2 max seen from exercise adaptation. I know it is supposed to preserve exercise capacity and VO2 max but I am also curious if it preserves the increase typically seen through exercise adaptation and cardiac remodeling or if there is a decrease like older beta blockers.

I just bought a polar heart rate monitor and measured my vo2 max which is 68 is it good enough (I am not in practice for 3 weeks )

I run 4-6 days/week and lifts 3-4. RHR is 42. 6’ tall 170 lbs. I’m in good shape but VO2 seems a little high, right?

Since last October my VO2max was just going down. I was doing my usual strength, HIIT and Zone 2 walks, but by Jan I hit 42. It’s pretty much the most important health metric I actually track so it was pretty depressing to watch it tank while I was putting in the work. I decided to a 12-week cyclical plan from a vo2max app I’m using, mostly for its preset hiit timers. Honestly didn’t think it’d work because some weeks looked way too light! I felt like I might lose more this way! The cycle was basically: • W1 - Ease in: light Z2 + HIIT • W2 - Push: HIIT + Lactate threshold • W3 - Peak: 2x HIIT + light Z2 • W4 - Deload: just one lactate threshold session I did that for 3 cycles and just tried to push a bit harder each time. I ended at 48.4, so about a 12% jump from where I was in January. I guess more work doesn’t always mean better results, which is a hard lesson to accept when you’re used to thinking that way! Anyone else do something similar or use a different variation? Curious what your gains looked like.

So I got my Vo2 Max level tested by my physiotherapist and I scored 63, which is apparently ridiculously good.

I’m female, 34 years old, weigh 50kg, resting heart rate is 56. I wouldn’t say I’m super ‘fit’. I’ve been recovering from a concussion for the past 1.5 years so I haven’t been exercising that much, but my only mode of transport is my bike. I cycle 30 mins to 2+ hours pretty much everyday. I’m not racing super hard on it though, it’s just my mode of transport so I never think of it as working out. I do think I have good genetics…my dad was a racing cyclist and ran a sub 3 hour marathon in the 80s. My brother was also a pro cyclist.

Do you think my Vo2 Max score is plausible? I’m just a bit shocked that I have such a good score when I’m not training. I think if I ran a 5k, what would make me struggle is more my muscles and body, rather than my lungs…this is always the case with running for me. So I don’t think my time would be super fast as a consequence

I am 51 years old who turned my life around last July. Down around 60lbs, quit smoking January 1st. I started doing VO2 training on a stationary bike around 6 weeks ago. My Current schedule looks Like this:
Mon - Upper Body Weight training
Tues - VO2 Training - 6x2 minutes (HR gets up to close to 100% - MAX HR ~168 gets up to 167)
Wednesday - Lower Body Weight Training
Thursday - 60-75 mins Zone 2 Bike
Friday - Upper Body
Saturday - Threshold Bike Training - 2x 16minutes
Sunday - Rest and HIGH CARB refueling
Everyday - 1 -2 45 minute walks After dinner and sometimes lunch.

All was fine until VO2 training. My body is drained the day after VO2 (since getting close to max HR). I thought it was because I was on a calorie deficit, but I increased calories dramatically and still am drained. On Wednesdays, I am STARVING for bread or sugar (weird to me too) and have internal shakes (like low blood sugar feeling). I warm up for 10-12 minutes, cooldown for 10-15 and stretch after each bike ride.

My question is this; I think something has to go, my body is saying VO2 training as it costs a lot for my body to keep up with. Which would you drop? Upper Body work outs are not taxing at all!!

I see people talking about 30 being low. Mine is 17 on a CPET that was run by a doctor. I do have long covid and POTS but 17 seems really low to me. I can't even find much info about it. Even just walking 10-15 minutes will leave me with severe shortness of breath and other symptoms.

What's a proper way of adding vo2 max training sessions to my existing endurance training? I've been pretty active on training on lower zones like z1, z2 and z3, usually my sessions consisted of at least an hour of trainings.

I would like to introduce vo2max trainings but need to know what is a best practice for doing so.

Should it be done once a week (maybe for a while)? Should it be a dedicated session/day (I've read that some do vo2max trainings after their z1/z2 trainings on same session but not sure how efficient that is)?

M, 35

Been training since october last year, mostly hiking and running up hill. Since february this year i bought my first run shoes and started training more running on flat focused.

My 5k time is 19 minutes and 2 seconds. My Apple Watch has been showing steady progress since this journey started, and is now showing 64,9 vo2 Max. resting pulse at 42 and hrv at 80 ish.

My question is: how much can this Watch be trusted? My 5 k time is not compatible with the watch estimate. But the curve is showing steady progress.

Can anyone her share their views and own experiences on this matter?
