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.
