No significant changes were seen during the 12 week training program in any of the power performance measures for either group. Although protein supplementation has been shown to significantly enhance power performance (Anderson et al., 2005), others have shown no significant differences between subjects consuming a protein supplement compared to placebo (Chromiak et al., 2004). However, neither of those studies used experienced strength/power athletes. It is likely that the lack of specificity between the training program and exercises used to assess power performance in this study was the primary factor that negated any potential effects of the supplement on power assessments.
