The following erratum, a correction to a published article, appears in the October 2015 issue of the Journal of Strength and Conditioning Research. A panel of reviewers has examined new information regarding questions raised on the reasons described in the article for subjects not completing the study.
The National Strength and Conditioning Association is issuing the erratum on the recommendation of the reviewers. Other than as is described in the erratum, this change does not affect the overall conclusion of the study.
In reference to Smith, MM, Sommer, AJ, Starkoff, BE, and Devor, ST. CrossFit-based high-intensity power training improves maximal aerobic fitness and body composition. J Strength Cond Res 27(11): 3159 – 3172, 2013, the authors have stated that the reasons for participants not completing follow-up testing, as reported in the article, were provided to the authors by the club owner. The club owner has denied that he provided this information.
After the article was published, 10 of the 11 participants who did not complete the study have provided their reasons for not finishing, with only 2 mentioning injury or health conditions that prevented them from completing follow-up testing.
In light of this information, injury rate should not be considered a factor in this study. This change does not affect the overall conclusion of the article.
