RETRACTION: D. García-López, K. Häkkinen, M. J. Cuevas, E. Lima, A. Kauhanen, M. Mattila, E. Sillanpää, J. P. Ahtiainen, L. Karavirta, M. Almar, and J. González-Gallego, “Effects of Strength and Endurance Training on Antioxidant Enzyme Gene Expression and Activity in Middle-Aged Men,” Scandinavian Journal of Medicine and Science in Sports 17, no. 5 (2007): 595–604, https://doi.org/10.1111/j.1600-0838.2006.00620.x.

The above article, published online on 20 February 2007 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, José A. Calbet, and John Wiley & Sons Ltd. Following publication, concerns were raised by a third party that portions of Figure 1 were duplicated. Internal investigation confirmed the duplications in this figure, as well as in Figure 2, and splicing in Figure 2. The authors provided original data, but these were not sufficient to resolve the concerns, and the authors were unable to provide a satisfactory explanation to address the concerns. The retraction has been agreed because of concerns that the images were manipulated, affecting the interpretation of the data and results presented. The authors disagree with this decision.
