adapting

[critterbug]

OK so I am totally 100% enamoured of my vk. However, Michelle's post got me thinking (i.e., when does the sense that the throat hit is too much go away). I ordered some carts, and actually like them *all* - I love the flavors. However, everything but my very modest 8mg cart makes me cough and burn. So I have in my [shopping] cart a bunch of low and 0 nic juices and carts, but I'm not sure whether to go ahead and submit the order or wait and see if I adapt to the higher nic carts. Or maybe I shouldn't bother with high nic anyway since even with my lil 8mg carts I have had ZERO cravings for a cig since I started vaping last Wednesday. Before I start worrying about mixing my own VGs until V4L gets them in, I'm thinking maybe my sense of throat hit will go away...

I'm thinking maybe the VG would work better for me since I'm not looking for throat hit and I'm concerned about this lactic acid issue. I'm training for a half marathon in March - and I've got some real serious training to do since the farthest I've run is 10mi - so I'm really straddling the line between hard training and overtraining. So of course I'm worried about the idea of PG and lactic acid. Has anyone had any issues with exercise and vaping? Or do you think the PG/lactic acid would affect recovery time?

Anyway, it's a bit laughable that I'm concerned about the PG's effect on muscle recovery - since I used to love to smoke a cig before a run - but I def. don't want leg cramping while I'm running. I can say that yesterday I ran 7.25 mi. and did not get any unusual cramping. I guess here's my question - to what extent does inhaling PG affect zeee muscles?

Thanks for reading that bunch of rambles! You all are wonderful and I'm so glad you're here! And I'm glad this forum led me in the right direction on the ecigs. I kiss my vk numerous times a day.

Hmmm. lactic acid: exercise :: sugar:exercise???
From Propylene Glycol : Propylene glycol is safe

"The use and effects of propylene glycol have been thoroughly researched. It has been used safely for more than 50 years, including adoption in health-sensitive applications such as food, cosmetics and pharmaceuticals, where the molecule mainly serves as non-active ingredient or carrier of other substances.

Studies have proven that propylene glycol has a very low degree of toxicity. In the body, propylene glycol is rapidly converted into lactic acid, in a similar manner to what happens with sugar (energy) in the muscles during sports.

For the environment, studies have shown that propylene glycol is neither persistent nor does it bio-accumulate - it is readily biodegradable. "

"...In the human body, propylene glycol is quickly metabolised and excreted. Its metabolic pathway is comparable to that of sugar: propylene glycol is rapidly converted into lactic acid, in a similar manner to what happens with sugar (energy) in the muscles during sports. It is the lactic acid in your muscles which makes them ache following intensive exercise. Lactic acid, the metabolite of propylene glycol, therefore, is also naturally present in our bodies. It is excreted via urine."

And from http://home.sprynet.com/~holtrun/dumping.htm

"Lactic Acid - energy source

Think lactic acid is bad for your running--then why do nearly
all our body systems produce it.
According to George A. Brooks Ph.D. Director, Exercise
Physiology Lab, at Berkley, “Lactic acid is not just a useless
byproduct of exercise. It is an energy source involved in using
glucose and glycogen. Oxidation of lactic acid is one of our
most important energy sources. Don’t let this important
metabolite scare you. But do still:
“Train with a combination of long submaximal training and
quality to minimize the lactic acid production and enhance its
removal.”

Which means: do your long runs each week, and speedwork at anaerobic threshold (15K pace) plus some 5K pace running and hill training. After all...lactic acid is not bad for you."

If someone could please help me figure out wth to make of all that! Sorry for the long posts and self-dialogue.

okay. here's a pretty interesting link : http://www.nytimes.com/2006/05/16/health/nutrition/16run.html

first, take everything here with a grain of salt, i'm not a doctor. but i know a bit about how the body works, so i'll try to draw what seem to me to be some reasonable conclusions.

i don't see PG affecting your muscle recovery at all... i'm not even entirely certain that inhaled PG would be converted to lactic acid *in your muscles*, but even if it were--that probably would *not* affect the level of glycogen (your immediate source of energy when running, stored glucose) in your muscles at all.

lactic acid naturally builds up as your body converts glycogen to energy, as a sort of byproduct. but lactic acid is *then* used as a different sort of fuel. you get tired out when you run out of glycogen, NOT because lactic acid has built up, but just because glycogen is a more easily converted source of energy.

*if* PG does get converted to lactic acid in your muscles after vaping, your body will use it as fuel. but remember, even if you vape 5 cartos daily, and even if 100% of the PG were inhaled, and even if 100% of THAT were converted to lactic acid, at a 1:1 ratio, we're only talking about 5 ml of fluid here.

now that, belletrist, is a feel good article. And your input is very helpful and clarifying. Not worrying about the PG anymore. THANKS!

Currently riding 20+ miles daily. No problems from vaping pg, just those darn hills!

delightful to hear. knew posting about it would help.

I walk 4 miles on an inclined treadmill (levels 10-12 are easy now (15 is the highest incline level, Matrix treadmill) 4-7x a week, I also swim afterwards and no problems yet. I have noticed decreased heart rate and increased stamina and much higher fitness level, level keeps climbing. I was exercising before I started vaping and getting hardly any results, started vaping the beginning of September.

critterbug, if the 8mg does it for you why bother trying to go to a higher nic? Zero cravings is great! congratulations!! stay with 8mg or lower, it doesn't seem like you need anything higher than that.

 

[Belletrist]

*nods* if anything, re: the nic level, i'd refill those carts with lower nic. or trade 'em out.

glad the post helped. <3

'm concerned about this lactic acid issue. I'm training for a half marathon in March

Your first? Good luck on your half!

Athletes will fair differently because our bodies are already well accustomed to processing ginormous amounts of lactic acid buildup.

I had a "charlie horse" in my left leg for about 15 hours after a couple weeks. I just sucked it up and went for a hard run and both my burn and the additional lactic acid from vaping was gone in a few hours. That may be just me, but I know my non-athletic friends who have switched have all suffered from it far longer than I did. [ie. YMMV] On the plus side, my times have plummeted incredibly. I didn't think smoking had effected me as much as it had. We're talking 30+ sec/mi at training pace.

The additional lactic acid buildup is trivial compared to a 10mi run, imho.


(I do fulls, ultras, tris, and competitive cycling [Former women's neo-pro back in the day, Cat 3 since I've started riding again])

 

[Adrenalynn]

i'm not even entirely certain that inhaled PG would be converted to lactic acid *in your muscles*

You'll find in the health section, common side-effects, that cramping due lactic acid build-up is a commonly experienced side-effect. Most respondents reported it from my unscientific [counting on fingers and toes ] survey of the reports.

I suspect the even more commonly reported flatulence is directly related as well, given change in ph.

 

[critterbug]

Mema, I think you're right. I think I secretly like the idea of nicotine and want to be able to smoke the higher ones. It feels psychologically... authentic. lol But, ok, I know you're right. I can get some 0mg peach cobbler carts and choc. sundae mmmm and roll with it. It really is the act of smoking that I've always loved. Concentrated breathing, all that.

Ugh, Pugz. 4 mi on an incline? Wild woman with burning quads!

Adrenalynn, thanks for the insight. It is my first half and I am *so* excited. -30 secs/mi over 13 would rock. Tis true, even with the lactic acid buildup [that I haven't actually noticed] I feel better than I did when I was smoking.

Thanks for all the feedback. Y'all are so wonderful and supportive.
