Don't Forget to Bring the Cooler !

Summer (with its heat and humidity) is almost over, but it's always a good time to think about ways to improve your performance.


For those of you living (and playing ball) in hot, humid climates, here's an interesting study from the United Kingdom that appears in the September 2008 issue of Medicine & Science in Sports & Exercise, the official journal of the American College of Sports Medicine.


Researchers wanted to examine the effects of drinking a cold liquid (instead of one at room temperature) on an athletes body temperature, heart rate, and endurance in the heat.


They took 8 young men (average age =22) and had them pedal on a bicycle to exhaustion in a hot and humid environment, once while drinking a warm (98.6 degrees fahrenheit) liquid and once while drinking the same amount of liquid at a cooler temperature (~39 degrees) .


They found that compared with the warmer liquid, drinking a cold drink before and during exercise in the heat reduced physiological strain (kept the body cooler) and increased the athletes' endurance capacity by more than 20%.


So what does that mean for you? The next time your team is scheduled to play a tournament outside or in a hot gym environment, it might be worth the cost and effort to store your drinks
(water, sports drinks) in a cooler. Don't like to be the one to carry the cooler(s)? Then you can ride the Cooler Train (above). It might help you get where you want to go.

I would be interested to know if results would be different if the subjects were doing some kind of intermittent sprint activity rather than a long distance event. More important, less important, no difference?

Excellent point, david!
While this research would be most relevant to people who were going out for a long distance bike or run, the use of cool liquids to reduce body temperature should, in theory, improve endurance in any exercise.
Would it make a great difference for one basketball game? Maybe not.
But if you're playing 3 games a day in a Summer tournament, or just trying to hold Winners Court on a hot and humid afternoon, this might help.
It should also be noted that the results might be even more significant if the test were performed on younger athletes (who don't cool off as well as adult athletes).
By the way, for you academicians out there, this also points out the need to look closely at hydration research articles to make sure that the temperature of the liquids provided is reported.
