I started hitting for about 40mins around 7.30am then stopped playing for a few hours before my game started at around 10.30am. I took alot of fluids (water and energy drink) after the hit out and by the time I started playing again it was around 30degrees Celsius and my whole body was feeling exhausted and did not want to be there.

On the way to the club (whilst driving) I had a can of energy drink (you know red bull). this was taken like 3hours before my game at 10.30am. On the court i started feeling like my whole body was numbing and really struggling for breath and just wanted to finish the game and sit in the shade. In the end, i just didnt feel like being there.

My question is, what was I suffering? Lack of fluids? dehydration? sunstroke? did the redbull affect my game? The annoying part was I lost to the heat and lack of motivation in the end.

Anyone can tell me what happened?

Some female pro once said (I think it was Kuznetzova [sp?]) that she drinks that much water/etc. before a match until her pee is clear.

So, one small can of red bull 3 hours before a match is definitely not enough! Especially not when it's 30C outside. :rolleyes: When I play I drink at least one bottle (1.5 liters) right before a match - that means I start drinking about one to 1.5 hours before -, not for practice though.

I often have problems with low blood sugar (Hypoglycemia (http://en.wikipedia.org/wiki/Hypoglycemia)) when I warm up and get my body going and then stop for 30-60 minutes. After that, I regularely have problems when I continue playing. The symptoms then are dizziness and sometimes I have a bright spot in my vision. I don't know if that is similar to what you have experienced, I just thought I'd mention it. ;)

If I will be exerting myself in hot weather, I will drink throughout the day before the match until my pee runs clear. I have heard this allows the fluids to get into your tissues, etc. Drinking during the match doesn't help much; it's too late.

I don't know much about Red Bull, other than it tastes horrible. I would never drink such a thing before a match. I'd probably have a stroke. :)

A buddy of mine drank a red bull before a match we played one time. He had to stop several times during the match because it was really driving his heart rate up and making him feel bad. Just drink water and if it is hot, then also drink an electrolyte drink.

Red Bull has both caffeine and a high sugar content.
The caffeine could have made you jittery (less focused) and pushed your heart rate up even more than just the exercise would have. A high heart rate is less efficient than a lower heart rate. And if you were partially dehydrated, the problem would have been compounded.
The high sugar content in Red Bull causes an increase in insulin output from your pancreas. The increased insulin will push your blood sugar down. But that is counterproductive if you are exercising, as your muscles are using a lot of sugar, and your blood sugar level can then fall too low for a time, leaving you listless.

NEVER drink a Red Bull (or similar drink) before playing sports. I was talking to a buddy of mine who is an actual distributor for an energy drink and he said he's surprised that more people don't keel over since it's so dangerous to mix it with sports.

Definitely something like this. Thanks guys. no more energy drinks for me before the game!

Caffiene increases urine output and therefore contributes to dehydration. Go with high volumes of sports drinks not energy drinks (which BTW don't provide any "energy" beyond their sugar content).

According to recent findings, the diuretic effect of caffeine is a myth. (I've previously provided links on this). Most current sources indicate that the dehydrating effects of caffeine is, at most, very mild or even non-existent. People need to pee after drinking caffeinated drinks because they drink to much liquid, not because of a diuretic effect.

I am unaware of a direct diuretic effect but as a known stimulant it should increase CO and thus renal blood flow.

Caffeine, as a stimulant, would increase the size or the population of Colorado?

CO = Colorado ?
CO = Carbon MonOxide ?
CO = Cardiac Output (ding, ding, ding! we have a winner)
