32GI

[rudi-h]

Something like oats without sugar.

Low GI bread with peanut butter

Pronutro is also Low GI I believe?

 

The above options are more like a list of "The three most horrible breakfasts ever". How are the hell are you supposed to wake up in a good mood knowing that you've got to stuff that down your throat first thing.

Fat burns in a carbohydrate flame .

 

I was speaking to the guy at the trail run and it was rather funny. Firstly, he tried to explain to me that it was lower GI because it was glucose...to which I said that glucose actually has a GI of 100... I know that it is in a different form, but still. He then tried to explain to me the benefits of an isotonic sports drink, to which I tried to explain that hypotonic is in fact better than isotonic...

 

Truth is, for high intensity it will not work. The actually product is marketed at endurance, so they even concede to it. Those people here that still want to believe that it will help them with high intensity training close to VO2 max are mistaken.

32 GI does make me feel better on a ride & nowhere near as hungry afterwards.

 

Like Rudi, though, I dont understand the science.

 

If i'm burning 900 calories an hour in a race as Polar tells me, how is a drink of 150 calories or so, able to help?

 

The non-spiking i understand, but then i didnt spike with cytomax.

 

So some simple explanation without graphs would help.

I must admit would be nice if they can give a type of low-gi mealplan?

Coincidently I just received a tub of 32GI (Peach flavour) this week here on planet Zug.

And tried it out yesterday albeit only on a 90 min medium intensity IDT session for which I normally would only drink water.

But seeing I’m thinking on using it soon during the LOTCR 3 day I thought I had better give it a go and see whats what…

 

Drank about 300ml 30 minutes before starting and then 1 x 750 ml water bottle during the 90 minutes, all mixed as per the instructions.

First impression was the taste, not bad but something different in a strange but ok sense of different.

During the training session I got a feeling that I was thirsty, this seemed to occur shortly after drinking 32GI

Other than that no noticeable difference or effect was observed.

 

So far it seems worthwhile to continue trying it and hopefully will be able to try it on a longer outdoor ride this weekend.

 

Hope it does not make me vomit like some other popular brands have (cytomax).

You will need to start loving simple things like oats in hot water if you want to make a difference.

 

I know have oats 2-3 times a day at work instead of bread often.

 

Very boring yes.

 

But something else I have found is that if you eat alot of boring food you end up not over indulging.

 

It is also easy to eat too much "good" food, but even good low gi sandwiches will make you pork up if you eat them all day.

 

So take boring food to work and eventually you will be forcing yourself to eat, because you wont be excited about what you have lying in your draw.

Seems that there is a slight tide against the initial hype of 32GI..

 

How ironic would it be if the hub sales of GI32 spikes massively after the ammount of time it takes to finish one tub, say 2 months.. Then they can take the same marketing graphs, add sales to the y-axis and swop the name of the brands of the lines..

[mojopup]

Didn't work for me either.

Back to Sportron BLITZ!

 

Sportron Drink rocks!! People underestimate it.

 

That said, I am in 2 minds about which is better. I like Sportron and 32GI.

I've read quite a lot of the posts about this stuff and finally seen and tasted it last night at the kinetic night trail run at randpark. I spoke to the salesman and he told me a similar story about the product. Non spiking, sustained energy for 2.5 hours, carbohydrates instead of sugar, don't need to take in any other food etc.

 

There is however something missing with the explanation / marketing of this product...

 

I am an engineer by profession, so firstly I do not believe anything without understanding it, and secondly I work with numbers and facts, not with subjective opinions.

 

The problem is this:

 

When I excercise / race hard, my body burns energy at a rate of roughly 1000 kCal / hour.

 

One serving of 32 GI only contains 189 kCal.

 

If I do the math, that means that for the estimated 2800 kCal that I burn during the 94.7, 32GI can only provide 189 of these. That is less than 7%.

 

If I compare this to my current racing food: (game and snackers bars)

 

2 litres of game (600 kCal)

2 x Snacker / chocolate bars (500 kCal)

1 x Gu (100 kCal)

 

That adds up to 1200 kCal, almost 43% of the energy that I burn.

 

I also realize that sports nutrition is not only a matter of "energy in" vs "energy out", and that the absorption rates, food type, GI and all of that stuff also plays an important role, but please provide a sound scientific explanation as to how it is possible that 32GI will sustain my energy levels "better", even though it has less than 6 times the energy than I currently take in while racing.

 

Please note that I am not running this product down. I have not used it and cannot comment, just curious.

 

Hi Rudi

 

You seem to really misunderstand how the body works when you are exercising. Firstly immediately available energy comes from your glycogen stores, muscle and liver. Muscle mass is larger and muscle glycogen carries about 800 – 2000 assuming your glycogen levels are stacked.

The liver ranges to between 250 – 500 calories. If your stores are full you can easily be carrying a few hours of already available fuel.

So glycogen loaded, with a decent pre-race meal, lets face it pretty much a lot of fuel already for the race. Secondly the aim is to spare the glycogen stores as much as possible. Why u would need to take in so many calories for an event thats less than 3 hours boggles my mind. This past weekend I managed a 4.5hour ride with 2 hours of intervals, just 32Gi and a decent pre-training meal. The bottom line is your calorie intake is way to excessive. I would say your intake would cause you to gain a lot of weight as opposed to losing, be very careful if this is how u r fuelling your body.

32Gi allows you to utilize your fat stores as a source of energy, being able to do this you can spare your glycogen stores, and save them for usage later on in the race. Did you know the average man can run 30-40 marathons on his fat stores alone, its a fact. The other thing you need to know is that professional cyclists actually usually only manage a calorie uptake of about 500Kcal per an hour. The body can only absorb so much, and glycogen cannot be replenished during exercise its impossible. The time that you shut your fat store tapping down is when u hit your anaerobic threshold, where u really need immediate fuel, at this stage it would be good to take additional calories something higher GI

 

I took this excerpt from Dr Allen Lim who is the official doc for Radioshack, actually says this on glycogen sparing:

 

Glycogen is indeed the lion's share of our stored carbohydrate, and it can be affected during exercise in the short-term by drinks, gels, and bars. However, the amount of “exogenous” carbohydrate that can be transported before one hurls, is limited. At best, I find that our guys can uptake only max 500 kcals an hour. So over a 5 hr, 5000 Kjoule day, they are just making it to the end with both exogenous and endogenous fuel. Thus it is extremely important that fat is used to help spare glycogen. Because the use of glycogen is dependent on the relative intensity of exercise as one gets relatively fitter, more fat is burned at a given absolute exercise intensity and more glycogen will be spared allowing for top end energy reserves for that late-in-the-day attack and win.

 

The point I am getting at is under racing conditions for 5 hours, no chance you can only use 32Gi and hope to survive you will need to take in additional calories for sure, or you will hit the hunger pains. But for 2-3 hours 1 gel or 1 little kick to the finish is more than sufficient.

Remember 32Gi is not there to prevent you from taking in additional calories. As I was explaining to my training partners the other day, it stabilises your energy levels, so that what you take in with the 32Gi will cause an increase the gylcemic load and lower the GI, causing a taper of your energy levels instead of a sudden drop. So by all means its fine to take in additional calories would say about 300kcals additional per an hour if you find the need, and the 32Gi will ensure that the energy taper is slow and gradual preventing the pendulum effect, it will make you feel far more balanced. But taking in 1000Kcals per an hour you are doing more harm than good to yourself and you should really re-visit your race nutrition.

 

all the best

Is it suitable for diabetics?

Definitely suitable for diabetics guys, we have a large community using it, I can put you in contact with some of them.

I tried this and had such a K@K ride. Epic pro works so much better for long rides. Just doesn't have enough in it to do anything

Hamster Dog sorry u had a bad ride, I am interested to know how long the ride was, how many rides have you used it on, and what did you eat the night and morning before this particular ride? The kind of intensity as well?

The fat burn thing worries me, I have 8% so can still loose a small bit, but what about really lean/skinny guys, it will surely be detremental to them using this ?

 

Rudi-h : Remember that you will have liver glycogen that should give around 2 hours of energy, also I think its more about how much carbs you need per hour than calories burnt, usually a gram of carb per kg bodyweight per hour (very rough estimate)

Weight weenie, mine is lower than yours LOL, u will never use it up, thats for sure.

[aungiers]

@MDW: I just want to state a fact or two. Firstly with regards to the Dr Lim quote; as far as I know glycogen is the only storage form of glucose.

Secondly I think a lot of confusion and misconception over this topic comes from the fact that people think that energy only comes from fat or carbohydrate; when in reality it is a combination of the 2 substrates with fat utilisation being less important at a higher respiratory quotient. dont know if that will help your argument
