Another Correction: in response to someone's enquiry about a sports science
user group I supplied a certain website address. The previous one
should be corrected to read:

http://www.sportsci.org

The www was accidentally omitted!

There is also a website which provides a list of numerous medical,
sports scientific and physiotherapeutic user groups:
