Re: supplementation for hiking?

actually they've shown that caffeine does not dehydrate you.MattCav wrote:Hammer Gel>>>>>>> Gu(GU) It's the stuff dreams are made of.
Gu sucks. Gu has caffeine (some do) which dehydrates. Gu is gross.
Hammer is good tasting. Hammer is made up of puree. Hammer is wonderful.
Sugar, sugar, and more sugar. And something to hold the sugar together.everyday wrote: And I have HEARD of GU, I ment , wtf IS it? like ingredients, lol.

actually not quite. gatorade and a lot of other supplements, yes, but gu...no.Sugar, sugar, and more sugar. And something to hold the sugar together.
interesting, ze. is caffeine still considered a diarrhetic then?actually they've shown that caffeine does not dehydrate you.
but it depends on context. I think they show that if you drink the same amount of liquid after drinking (coffee vs non), you have same hydration level. however my own experience says that perhaps you naturally drink less water after drinking coffee (in total), so you end up dehydrated later on.
still, it should dehydrate you during the hike so much...

Thirty is great. It wasn't until my late 30's that injuries started piling up. TAKE CARE OF YOURSELF. I'm not convinced I took the best care of myself.MattCav wrote: 30 aint so bad. im in the best shape i've ever been in. we're as old as we let ourselves be
Well, i hike n run at least 8 miles a day on the trails out here with at least a 2200elev gain, 3 days a week, and 2 days a week I do 16-20mi with at least a 4500ft-6000ft elev gain. so I dont need a "different" experience. I feel fine after, and the day after all my workouts. So ima stick with just eatin fruits, veggies n dead animals for daily nutrition, and no processed/ chemically stuff. thanx anyway ima stck with my pineapple/oj/water combo, and chocolate milk. I dont like ingesting stuff i cant pronounce, and NO fluids should have a whole paragraph of ingredients! thats crazyMattCav wrote:
and, everyday: i just hit 30 last week... the hammer gels (similar to gu) that i take seem to provide me with a great amount of energy for doing extended hikes (10+ milers). i've tried just using trail mix and fruit juice... and i'm pretty sure it was not the same experience, for what its worth.
i've wondered about that, knowing what i've heard, but i leave home with 8 ozs of caffienated mint tea and have a soy hazelnut latte before most hikes if i can find a Starbucks within reach. i have never become dehydrated (yet) from that combo. i then try and down 6-12 ozs of water before i begin my hikes and i wear a Camelbak reservoir in my pack, so i am constantly sipping water (and peeing!)Zé wrote: actually they've shown that caffeine does not dehydrate you.

That sounds reasonable. One has glycogen stores sufficient to fuel around 20 miles on level ground. Head up Skyline and you're burning enough extra calories climbing to be depleted well before reaching Long Valley.everyday wrote: Is being glycogen depleted what makes the big muscles in my legs/thighs feel week on long uphills? i dont feel hungry, but my legs do! lol -so if i eat, even just a lil, then my muscles feel happier
more or less, yes. there could be other reasons for fatigue, but glycogen depletion is a biggie. even if you are going for a mile run, larger glycogen stores will make you feel like you have more energy (because you do) and you go at a faster pace (burn more glycogen anaerobically) because you have more.everyday wrote: Is being glycogen depleted what makes the big muscles in my legs/thighs feel week on long uphills? i dont feel hungry, but my legs do! lol -so if i eat, even just a lil, then my muscles feel happier
LOL!I just let Ze pull me in my carbon fiber wheelbarrow.
ok, so here's a question for you, ze: if one goes at a pace of 70% their max HR for 5 hours... and another person goes at a pace of 85% of their max HR for 3 hours... is it reasonable to think that the the second person may need to eat more, citing their likely depleted glycogen stores? In my own experience, I've found this to be the pattern.

I resolve to only consume live animals from now on.MattCav wrote: This is becoming an interesting thread. It's cool to see how different things work for different people. Perhaps one reason I am a bit more intentional about my sports nutrition is that I do not consume dead animals (or live ones)...
Glycogen is one form of stored energy -- calories. To a good approximation, you burn a fixed number of calories to go a certain distance on flat ground, regardless of speed. You burn additional calories going uphill -- a fixed number of calories for a certain elevation gain. So, if you go slowly for 5 hours or intensely for 3 hours, you will be more or less equally depleted of stored energy if you covered the same distance and gained the same elevation.MattCav wrote: if one goes at a pace of 70% their max HR for 5 hours... and another person goes at a pace of 85% of their max HR for 3 hours... is it reasonable to think that the the second person may need to eat more, citing their likely depleted glycogen stores?

Really? I'm surprised by that. I would think that it would be more like an automobile. If I drive X miles at 85 mph, it will take a lot more gasoline than if I had driven the same X miles at 25 mph. You're saying it does not work that way with hiking? I find that very difficult to believe.AlanK wrote: To a good approximation, you burn a fixed number of calories to go a certain distance on flat ground, regardless of speed.

I guess the 5/75 and 3/85 numbers came from trying to consider different fuel sources... I always learned that if one is in the aerobic HR zone, they burn mostly fat, but if they are in the anaerobic or redline HR zone, they use up way more of that stored glycogen. I remember seeing your blog about that, too, ze, and it showed me why I suck at hiking by myself (I don't pace myself nearly enough when I hike alone...my average HR is usually in the low to mid 80 percentile over 4-5 hours +).glycogen stores can be depleted extremely rapidly when using anaerobic metabolism. the ratio of glycogen / calories changes between anaerobic and aerobic.
if there weren't other limiting factors that fatigue you when 'sprinting', you'd probably deplete glycogen stores in like 10 mins!
if you were trying to deplete glycogen as quickly as possible, maybe 3 min sprints with rest, repeat 5 times.
as for 5 hours at 75 vs 3 at 85...i dunno exactly what the intensity / duration curve looks like...but both may equally deplete glycogen (possibly). even though calories burned may be different.
