Don’t let the summer heat burn your performance. Here’s a tip that will make your next run better: Freeze Your Sports Drinks!
A study conducted by a researcher at the University of Chicago found that runners performed significantly better in a run to exhaustion in the heat when they consumed a slushie beforehand instead of a cold drink. Both drinks contained sugars in amounts similar to sports drinks. The slushie was just colder and reduced both core body temperature and perceived effort during the run.
So before your next race or hard run in the heat, consider freezing your sports drink and taking it in slushie style!
