The 1993 definition also starts with the condition of it being a physical activity which is the stumbling block. Many sports have a negative health impact as well as a positive one - American football and boxing come under this category but it would not matter if they had no positive health associations at all, since that part of the definition comes under the OR and they would qualify under the competition sub-clause. Parsing the definition gives:
sport =(physical activity) AND (((imp physical fitness) AND (imp mental well-being)) OR (forms social relationships) OR (obtains results in competition))
A pub crawl is a physical activity that forms social relationships, ergo clearly a sport! In any case, this "physical activity" part is the reason why the question of whether the 1993 or the 2011 definition should be used is so important. But showing health benefits alone is not enough under either definition.
