This statement leads me to be less inclined to believe anything she said to me.lowendrick said:...I'm also not real comfortable with the caffeine component...seems counterintuitive as an ingredient to consume when exercising...
Article and quote from said article on the benefits of caffeine to endurance athletes. This was one of the first articles I found when entering "caffeine and aerobic exercise". Google it yourself and you will find hundreds of hits from reliable sources. Your friend seems to be speaking more about personal preference than with any actual proof. She also doesn't seem to understand nutrition and effects on performance. Is has been shown in many studies that caffeine can benefit certain types of athletes, especially endurance athletes.Andrea138 said:Other than just being incredibly overpriced sugar that can contribute to tooth decay, there's really nothing wrong with Gu (or any other gel) if it works with your stomach & keeps you going.
I am with you on the caffeine issue. I think my friend is wrong here. And no, she does not have experience with performance athletes. She is just speaking from a more general knowledge base. Clif gels have 2 varieties with caffeine so they get it too.ibexbiker said:Article and quote from said article on the benefits of caffeine to endurance athletes.

" Research provided by the American College of Sports Medicine (ACSM) has shown that ingestion of 3-9 mg of caffeine per kilogram (kg) of body weight one hour prior to exercise increased endurance running and cycling performance of well-trained, recreational athletes in the laboratory. This correlates to approximately 2-6 regular size cups of coffee.
Improvements have been shown in athletes that perform short-term intense (near maximal) exercise lasting approximately five minutes. The reason may be a direct effect of caffeine on muscle contraction during anaerobic exercise.
The common explanation to why endurance is improved with caffeine is that muscle glycogen is spared. Glycogen is the stored energy in the muscle tissue that is broken down during exercise. Studies suggest that glycogen sparing may occur as a result of caffeine's ability to increase fat availability for skeletal muscle use. It is important to note, however that studies cannot fully explain the ergogenic effect of caffeine."
Gu contains fructoseBioteknik said:"clean" foods like the cliff stuff doesn't provide better energy sources, they might have more nutrients in them, but they are also processed as well. On a molecular level your body doesn't care where the nutrition came from and can't tell a difference.
There's nothing wrong with simple sugars during a workout (as long as it's not just glucose, or fructose as that can cause stomach cramps)
I don't like solid food during hard workouts or racing either. Brown rice syrup is typically listed as 50% soluble complex carbohydrates, 45% maltose, and 3% glucose. While I am still trying to find out exactly what those complex carbs are, as it's not listed anywhere, the maltose and glucose absorb about as fast as maltodextrin so you can still get that fast kick, but you still have something left for later. As you take gel shots once every 20-30 min, you don't want to have a kick for just the first 5 minutes, IMO.d-town-3- said:the one reason i prefer GU's over a cliffbar etc, is the moment the GU hits my mouth its absorbed and used instantly for your immediate energy needs. The worst is when iam pumping out crazy watts with labored breathing and all i have is a powerbar. I can watch my heart rate increase just from trying to chew that thing, it screws with my breathing. The GU is like a line of coke(not promoting drugs), for athletes. Suck it down and feel like a new rider. I crave those little jelly packs, its a mental boost when you eat it.
