First Ventilatory Threshold and Fitness

Hi all,

I was reading through this entire thread. So much great information and science. I have a question that some of you might be able to help me with.

I had Vo2 max tested at a sports science lab. My Vo2 max was fine. It was 48, which is 114% predicted. Nothing amazing, but I have been ill and haven’t worked out like I used to. I’ve had unexplained shortness of breath. No doc had been able to tell me what’s wrong.

What I noticed from my CPET test is that my VT1 was 44% of my Vo2 max.

Have you seen number that low? Any clue what this indicates? I thought normal VT1 was much higher than that. Am I overly concerned about this or can VT1 indicate something important about my breathlessness with exertion? Is VT1 very improveable?

Any thoughts would mean a lot!
