The Journal of Strength and Conditioning Research has retracted the article entitled “CrossFit-based High Intensity Power Training Improves Maximal Aerobic Fitness and Body Composition” by Smith, MM, Sommer, AJ, Starkoff, BE, and Devor, ST, published in the November 2013 issue of the Journal of Strength and Conditioning Research (Vol. 27, pp. 3159-3172). The Journal of Strength and Conditioning Research was advised on May 4, 2017 by one of the authors that the study was not conducted under an IRB approved protocol for that study, as was stated in the article.
