45 physically active men about 30 years of age from Phoenix , Arizona participated in two workouts about three weeks apart. Their workouts included 60 minutes of strength and cardiovascular conditioning followed by performance tests in broad jumping, weightlifting and stationary cycling. This study evaluated whether or not drinking cold water versus drinking room temperature water made any difference as far as regulating internal body temperature and preventing dehydration. What do you think the findings of this study might be?
If you thought that drinking cold water during strenuous exercise is faster and a more effective way to regulate internal body temperature and preventing duration, then you are correct. In this particular study participants consumed identical portions of water at 39° Fahrenheit in one group session and 72° Fahrenheit in the other. During the workouts, the participant’s core body temperature increased 2.2% in cold water experiment and 3.1% in the warm water condition. Cold water slowed the rise in temperature. While average core temperature increased from 98.7 to 100.2 degrees Fahrenheit with cold water and from 98.3 to 100.4° Fahrenheit with warm water. This study was found in the November 6, 2012 edition of the Wall Street Journal.
This finding may explain, in part, Secretariat’s secret in his ability to run fast. For every run, Secretariat’s water bottles are put in his refrigerator overnight regardless of the temperature outside. You might wonder how he does this. Well, he uses a holster to carry his two water bottles. Since I carry my two water bottles, I plan to keep them in the refrigerator overnight as well but only during the summer during warm weather.
All you that do or perform strenuous exercise consider using cold water if you’re not already doing so. I’d be interested in hearing your results and experiences with cold water.
On Monday, Chris, Secretariat, and I hit the trail for a short loop. During the evening, Chris’s hosting Monday night football( lots of laughter) and we will be joined by Perry and Lon. Tomorrow, Madhu, Farah, Secretariat and I plan to do a 10 mile or so trail run. We did that and made plans for a long trail run Saturday.
Keep moving and laughing as long as you can.
