Concentric and Eccentric: Muscle Contraction or Exercise?

摘要

This inclusion considers the use and possible misuse of the terms "Concentric and Eccentric" in three possible contexts: first, the origin of terms; second, different approaches; and third, the possible uses. To the best of our knowledge, three articles (Aboodarda, 2011; Bdel-Aziem and Mohammad, 2012; Krol and Mynarski, 2012) have been published in the Journal of Human Kinetics misusing the term "concentric/eccentric exercise" while none of the articles have used the terms correctly. The purpose of this letter is to foster the use of the terminology 'positiveegative work' together with 'concentric/eccentric contraction1 to ease references search (i.e., through key words) and comprehension.
