A couple good topics for this week’s round-up. Who could pass up the headline "Slushies vs. Frozen Underwear for Hot-Weather Workout"? Not only a killer headline but an interesting topic. Also, how important is eating breakfast for your running if you run in the evening?
Slushies vs. frozen underwear?
Would you rather wear frozen underwear or eat a slushie? Easy call, right?
Well, maybe not if you’re interested in performance in hot weather. Or at least not the answer you were just thinking.
But the results also indicate that if you use only one type of precooling, you might want to concentrate on icing your skin instead of your stomach, since the effects seem to linger longer.
It’s important to note that both methods of cooling had benefits but it appears cooling the skin is more long lasting than cooling the gut.
The practical take home of this is do what you can to keep cool before a warm weather run. Cooling the skin is better than cooling the gut but both are good.
Eat your breakfast!
We always hear about the importance of breakfast. How important is it for runners?
Apparently, very important:
They measured exercise performance (30 minutes of steady-state cycling followed by a 30-minute time-trial) at 5 p.m., with or without breakfast. The subjects had eaten as much as they wanted for lunch (and the subjects did indeed eat about 200 calories more after skipping breakfast compared to when they ate breakfast), but this wasn’t enough to make up the deficit. Time-trial performance was 4.5 percent worse after skipping breakfast.
As noted in that article, it is important to note that these were habitual breakfast eaters. It’s possible that those who don’t normally eat breakfast would experience different results.
