This article has been retracted at the request of the authors and editor. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: It is a duplicate of a paper that has already been published in J. Sports Sci. Med., 6 (2007) 429–433. When submitting the manuscript to another journal, i.e., Pathophysiology, there was a misunderstanding on the part of the authors that the option to publish in Journal of Sports Science & Medicine had closed as they were unable originally to pay the required publishing fee.
