You should think about the operationalisation of the question. What is the worth of a one rep eccentric test. If you shouw that it improved, so what...How is that of any benefit to someone unless they function as a human forklift once every 20 minutes??? I would look for a better measure than this and thing about what it is that is the benefit to the individual who would undertake the training that you wish to give them....lets keep research useful...sorry don't mean to be an arse!!!!
