Of particular interest, however, was the fact that Dr Berkoff preceded his article with a definition of ‘hot’. Within sports and exercise medicine, and indeed in all scientific disciplines, definitions are of great importance. In fact, “The primary advantage of operational definitions lies in the unification of science and the resolution of controversy.”2 It is the definition and use of a term within a topic that might also be deemed as ‘hot’ that this editorial attempts to address: Intensity in resistance training (RT).

Thus, this editorial seeks to ask the readers of BJSM, and the wider community involved in RT, to consider the use of the term intensity as it stands and whether both sides of the disagreement are defending inappropriate idioms. More specifically, however, it …
