CrossFit, America's high school weight room for adults, is suing the National Strength and Conditioning Association for publishing a study it says is "based on data that is objectively false" and "intended to scare participants away from CrossFit."
The study, published in November by the NSCA's Journal of Strength and Conditioning Research, is titled "Crossfit-based high intensity power training improves maximal aerobic fitness and body composition." Researchers from Ohio State's kinesology department examined the changes that occurred in a group of 54 CrossFit participants (all of whom, amazingly, were on a paleo diet) over 10 weeks, concluding that subjects lost body fat and increased their VO2 max, or oxygen consumption. But they also included one sentence that has become the center of the suit:
Of the 11 subjects who dropped out of the training program, two cited time concerns with the remaining nine subjects (16% of total recruited subjects) citing overuse or injury for failing to complete the program and finish follow up testing.
