Q: Caffeine and Athletic Performance?

(src) Glycogen "is the main form of carbohydrate storage in animals and occurs primarily in the liver and muscle tissue." (src) Granted those two sources are not good references. I need to do additional research. However, if true, would diet caffeinated beverages not work for diabetics (since the caffeine increases their sugar level)? Also, would caffeinated beverages degrade athletic performance by depleting your muscle glycogen supplies? More investigation is called for. Any insight anyone?

And I'm going to do more research as well- since I may be diabetic, my father in law is diabetic- and he's addicted to Diet Coke...

I'm addicted to Diet Coke too... (1)

I hope you're not diabetic! One reason I started exercising is because I was afraid of becomming obease and developing diabetes. I wonder how many so-called "health" drinks and foods actually increase your blood-sugar level significantly.

Although my mom doesn't have it, her brothers and my grandfather on her side are diabetics. Also, my father, grandfather, and uncle on this side all have it. So I have to be careful!

I'm a T2. Diet caffeinated drinks and coffee (sweetened with Splenda) don't bother me, but I also exercise quite a bit: I'm up to 120 miles so far this year.

The best way to tell how it affects you is to get yourself a glucometer and test your blood glucose every 15 minutes for about 2 hours. At a dollar a test strip, that's 9 bucks (including the one at t=0). I write it off as entertainment.

If you wish to avoid being a T2, you can. There are some important things to keep in mind:

1. Get approval from your doctor for exercise. Exercise burns glucose and fat and builds muscle. The internal fat between your organs seems to be the big culprit in causing diabetes. Liposuction won't do much. Both weightlifting and aerobic exercise help, with aerobic having more immediate effects on blood glucose. If you can only do one, do aerobic. Aerobic exercise should be for at least 30 min., every other day. Aerobic exercise in the "vigorous" range is better, but anything's better than burning yourself out and stopping exercise. Don't try for "vigorous" right away. Start out walking -- even 20 min. miles will help.

2. Diet is important. A diet with 200-500 cal less than you need per day is sufficient to lose weight without provoking your body to go into starvation mode -- that's about .5 to 1 lb lost per week. Your diet should be high fiber and low fat. Believe it or not, high carb foods won't cause you to become diabetic, although you really should take it easy, just for nutrition's sake.

3. Weight control is major. Five lbs lost will result in a major decrease in your risk factors. If you lose weight too quickly or lose too much, you will rebound. Slow is best.

4. Ask your doctor if you are a candidate for an antidiabetic med. to help you avoid diabetes. There's a lot of disagreement on this one among doctors; go with what your physician tells you.

5. Diabetes sucks big time. Avoid it at all costs!

I hope I'm not too- but I got a bad staph infection from a hobo spider last September, and the speed of healing wasn't what my doctor wanted to see, so he mentioned it. I don't even want to know until I've got health coverage again, so I'm kind of avoiding it for the time being- exercising and trying to get back into shape.
