Asthma thresholds

Post by nates » January 11th, 2022, 9:44 am

I ran across a paper this morning about aerobic threshold and exercise induced asthma after bumping into constriction a little lower than normal. In the past, 160 bpm was safe, but I was feeling a bit at 145-150 today. I backed down to 140-145 and had no further problem.

The paper seemed to suggested the lower threshold was due to being sedentary, not asthma. I use to joke before I started exercising that I learned long ago that if I left my asthma alone it left me alone.

Anyone with EIB/EIA found anything useful or interesting when you started trying to get fit? Are your thresholds consistent with your fitness levels?

I was diagnosed with asthma in October, but I question the diagnosis as my only symptom is shortness of breath upon exertion.

As I have over a million meters on my Concept2, exercise has been part of my lifestyle and the SOB is a real PITA when hiking, especially uphill.

Oddly, I don't get SOB when doing SS on my erg.

Does your SOB include constriction or wheezing? That's the hallmark of EIA.

I really suspect the lactate threshold is a key parameter here. But I can tow at higher heart rates than I can run at before constriction. Running just blows past it in couple minutes.

No wheezing and rarely any constriction that's noticeable.

Did some short high intensity work this afternoon. That left me gasping for air.

Have you increased your stroke rate, changed the time that you row, or do you know if you've subtly changed your breathing sequence?
48 HWT; 6' 4"; 1k= 3:09; 2k= 6:36; 5k= 17:19; 6k= 20:47; 10k= 35:46 30mins= 8,488m 60mins= 16,618m HM= 1:16.47; FM= 2:40:41; 50k= 3:16:09; 100k= 7:52:44; 12hrs = 153km

Rate was about the same but I rowed later in the afternoon.

Next time I'll take a puff of albuterol 15 minutes before starting the workout.

Also, if in northern hemisphere, consider lack of humidity this time of year.

Not sure if this is a credible source... https://kidshealth.org/en/parents/weather-asthma.html
" Cold, dry air is a common asthma trigger and can cause bad flare-ups. That's especially true for people who play winter sports and have exercise-induced asthma. "

Some warnings about getting humidity too high or too low.
