no it's not the "bikes and cars don't mix" article. some MD namepd Gupta from CNN says you only need sports drinks for events like the "iron man" that last 12+ hours.

I think the doc was talking off the top of his head rather than basing his conclusions on research or actual experience. When I go on long rides, particularly on hot days, you can see the salt crystals on my helmets straps, jersey and shorts. I have found that my right calf often starts to cramp (it feels like a muscle pull) on hot days, but the cramping goes away if I drink some Gatorade -- or it doesn't happen at all if I start out with a bottle of Gatorade. It works for me, particularly on long rides.

Gatorade was originally developed for the University of Floida Football Team, which kept losing players to heat prostration in the 2nd half. The Gators became known as a second half team after the invention of Gatorade.

I don't think they were playing any 12 hour football games.

As far as cramping, before a Century or a long ride, I chew a couple of Tums for calcium before the ride, as well as hydrating with Cytomax, GU20, Hammergel or Accelerade during.

We have two MD's in our tri club who do ironman events, and their talk on nutrition during extended events basically agree with this premise. They told us that there is such a requirement to intake carbs during the race that they normally use only sports drinks (various types not just gatorade), plus solid food and gels....they also say that they lose so much sodium that they must intake food on the bike high in sodium, such as pretzels....Their point being if they were taking in half their fluids in the form or just water, they would have a much harder time getting the necessary required carb intake.

I am not sure the question I responded point was that during endurance events these MD's do not normally use any "straight water"...the do "sports drinks", gels, and some solid food while on the bike.

Another thing you may want to try is Endrolytes from One capsule contains 100mg Sodium Chloride, 50mg Calcium, 25mg Magnesium, 25mg potassium, 6.6mg VitaminB-6, 1.6mg Manganese, 50mg L-Tyrosine. I use them on my long rides it hot weather 1-3 caps per hour. used them on my 6.5 hr ride on Sunday here in Charlotte, NC area temp was about 96-98 with 40-50% humidity didn't have any problems with cramps or anything of that nature. Even on my 2hr rides I carry 1 bottle water 1 Bottle cytomax works fine .

There is some truth to that. It really has a lot to do with your overall diet too. Personally I shy away from sports drinks because the sugar does tend to cause stomach cramping.
Usually no stomach cramps if sugar is below 7% solution. -nmTig

This guy's never heard of my favorite century, the Hotter'n Hell Hundred. The 91 mile rest stop looks like a MASH unit with IV's plugged into the arms of all those riders who thought water was enough. And for some folks the IV's were too late.

When the doc refers to 'most people' being better off with just water, he is probably right. Most people don't need the carbs and what not from sports drinks at the intesity and duration that they work out. Most people tend to drink sports drinks faster than they were designed to be consumed, and this can cause stomach cramping due to the fact the digestive system can't pass the sugar as fast as it is being taken in. Drinks like Gatorade were developed at a ratio of 6% glucose meant to be taken in at a rate of 8oz per 20 minutes or so. Also, your liver has enough glycogen stores to get you through about 2 hours of pretty intense exercise, so most people aren't running this out and don't need the extra carbs. Most people, the way that the average person works out doesn't need a sports drink. I'll agree to that much.

I would disagree though that an athlete doesn't need something along the lines of a sports drink in exercise lasting more than 90 minutes. An athlete like a cyclist exercising for longer periods of time will run down their glycogen stores in their livers, and need to replenish these, and keep their blood sugar levels up. This is why the carbs (glucose) in Gatorade is good. I would also disagree with the doctor that these drinks have enough electrolytes and sodium to keep up with an athlete in training. Most of these drinks are actually inadequate to replenish these losses, and it doesn't take an ironman to get way too low. Ever gone on a ride in which your sweat started to taste good or sweet? You were running out of sodium. Happened to me last weekend on a sub three hour ride in the heat. Definitely doesn't take ironman duration.

I think this guy is relaying info off the top of his head that applies more to the person who thinks walking around the block is strenuous and quaffs Gatorade the whole way. I don't think he is really filled in as to what an athlete needs during exercise, or the finer details of the amounts of sodium and electrolytes in sports drinks. Doctors are great, but most only take a solitary course or two in nutrition. I think when many doctors talk about exercise or nutrition it is like a dietician or physiologist talking about what antibiotics to take. Might have read something, but should probably leave it to those in that field. My 2 cents FWIW.

Let's think about this for a few seconds. This board is dominated by higher intensity bike riders. How much of the general populous ride or run or something? Very few I think with an intensity level required to drink a supplement on a regular basis.

It's more simple than that, and less scientific...miposy

You results may vary, but my personal threshold is about three hours.

For rides shorter than that Cytomax does not seem to make a difference for me, but for rides longer, Cytomax has been the difference between cramps and no cramps. Note that at less than 100 miles a Cytomax before the ride is sufficient, but if I go longer, another Cytomax at 100 miles is quite helpful.

The effect is even more exaggerated on MTB climbs, where I can start cramping as early as two hours if I don't Cytomax before the ride, and where I always do another at the top of the climb (usually two to three hours).
