Research on Cramps (in rugby)?

[Grant Jenkins]

I have just done a brief lit review on Pub Med and the NSCA website for info on cramping.

Current research suggests that cramping is associated more with EMG activity than the "mythological" hydration, or electrolyte levels. Schwellnus seems so be the leading reseacher in this area.

If you have research (not published at the Gatorade Sports Science Institute!!) that suggests otherwise, please email me - gjenkins@bbc.qld.edu.au ).

Thank you,

One thing is definite that they appear to be much more frequent in hot weather. Whether this is direct heat effect, extra fatigue or dehydration is debatable, but there must be something doing.
