Letter to the Editor

Dear Editor,

Thank you for allowing us to respond to the letter by Cross et al. [1], which we have read with great interest and amazement, given some of the unfounded comments made. First, we must emphasize that the meta-analysis published by Alcaraz et al. [2] did not intend to analyse the effects of resisted sled training (RST) loading and training status on sprint performance. This meta-analysis performed an updated systematic review to determine the effectiveness of RST on sprint performance, and secondarily, to explain which variables produced a greater improvement in sprint performance in both the acceleration and maximum velocity phases.

Secondly, Cross et al. [1] criticize the operational basis of our review, when in fact all recommendations in the PRISMA statement [3] were followed. We clearly formulated the question using systematic and explicit methods to identify, select, and critically appraise relevant research, and collected and analysed data from studies included in...
