Although i'm rather sceptical I'd like to see that article.
Top Velo, (in French), August 2011, no. 173. Article by Guy Thibault Ph.D.
I've sniffed around the net a bit, and there is at least one similar article which seems to refer to the same study or studies:
http://www.twc.bc.ca/storage/Muscle%20Cramps%20in%20Athletes.pdf
"This month a study from the University of Cape Town, South Africa showed that the athlete who is most likely to suffer muscle cramps is the one who runs the fastest and the one who has had previous muscle cramps (British Journal of Sports Medicine, June 2011). Of 210 triathletes competing in an Ironman triathlon, 43 developed severe muscle cramps, while 166 did not.
There were no significant differences between groups in any pre-race or post-race blood mineral levels or body weight changes (a measure of dehydration).
This supports many other studies that show that the most likely cause of muscle cramps in conditioned athletes is muscle damage. The most likely causes of muscle cramps in out-of-shape exercisers are lack of salt or water (1)."
Original BJSM article would appear to be this one: http://www.ncbi.nlm.nih.gov/pubmed/21402566. There are a number of other articles referring to it and to ongoing work in this area by Martin Schwellnus, for example:

And if you want to jump into the debate:

FWIW, I have no opinion or expertise in this, just passing on the info. On the other hand, having had cramps last weekend for the first time ever on a bike while doing some strenuous hill repeats on the tail end of a pretty hard 100 km ride (during which I was supposedly well-hydrated and electrolyted ...) I'm more inclined to go with it than not. I might try some longer water-only rides to see what happens.
