I've generally noted that vaping doesn't seem to harm my capacity for exercise, but today I noted something that's worth attention.

I was biking up a closed road, starting at an elevation of 1000 feet, the hill rose steadily to 1800 feet by mile 2.7, about a 5.5 percent grade. Having vaped heavily in my car along the way to this closed road, I found that my lungs were not up to the deep breathing necessary for the chore. They were very shallow and tight. I then spent 2 miles on relatively flat road, and I was able to breath more comfortably as the oxygen demand was much reduced. This was followed by a mile and a half steeply downhill to 1300 feet where I let gravity do the work. At this point, I turned around after covering a total of 6.2 miles, and climbed back up 500 feet in a mile and a half. By this time, the breathing had seemed to work my lungs looser, and they didn't seem so shallow or tight.

So as far as I can see, during this 12.5 mile total distance of up and down hills, the pre-trip vaping certainly contributed negatively to my performance.

Still, while I suffered the tightness and shallowness, I didn't suffer the pain, fatigue, and wheezing that I would associate with analogs. and while the shallowness and tightness were a factor, they seemed to have worked themselves out by the time I turned around at 6.2 miles to return the way I'd come.

Bottom line, vaping was not good for strenuous cardiovascular exercise, but it still wasn't as bad as analogs.

The mix I'd vaped prior to hitting the road on my bike was 60/40 VG/PG with 12 mg nicotine.

I'd say the tightness/shallowness didn't really bother me on the non-strenuous sections, but on the extended uphills, I really noticed the effects. I guess by the time I turned around, I'd "worked out" the VG/PG/Nicotine effects such that the return trip was much more comfortable on the uphill pushes.

It makes sense that I should refrain from vaping in the hours leading up to strenuous exertion.
