Oddly popular for such an uncomfortable practice, the ice bath is hotly (sorry) debated in the fitness world. A new study adds fuel to the fire with the finding that a chilly dip after a tough workout won't do anything to ease soreness or reduce the loss of strength that's typical post-workout.
In the study, researchers had 20 active men run for 40 minutes downhill on a treadmill to induce muscle damage. After, half sat for 20 minutes in an ice bath at 5 degrees celsius (that's around 40 degrees Fahrenheit!) while the other half stayed warm and dry.
When it came to a battery of post-bath tests, including quad strength, thigh circumference and reported soreness, there was no difference between the two groups, HealthDay News reported. The men who sat in the frigid tub did show alower measure of a particular blood marker for inflammation, but not significantly, according to the study.
Lead researcher Naomi Crystal said in a statement that she's not entirely convinced ice bath devotees should hop out of the tub, but advises exercisers to use them sparingly, after the highest-intensity workouts. "If it doesn't work, you don't want to waste your time," she said. "For day-to-day athletes, I wouldn't recommend them. They're painful, and they're time consuming."
