I don't know the answer to that question, but as an example take look at the
source code involved in sending the next message to the list, written by
Steve Aspinall in HTML. So as not to annoy people I have appended the code
at the bottom of this list. You can see the possibilities for slipping in
some malicious code (no offince Steve, just using your message as a
convenient example!).

Nicola,
Back on the 17/12/99 I sent a post with some views re warm ups, =
have a glance at it via the archives, you may find some of the =
references useful. Also have a glance at: =20
=20
Ekstrand J, Gillquist J, Moller M, Oberg B, Liljedahl S.O. Incidence of =
Soccer Injuries and their Relation to Training and Team Success. =
American Journal of Sports Medicine, 11(2):63-69, 1983. =
Amongst other things the authors comment on injury incidence as it =
relates to warm up. =20
=20
I think the biggest problem with justifying warm ups, cool downs and =
stretching is finding quantifiable evidence that they improve =
performance, reduce injuries, speed recovery etc. Take for example the =
relationship between hamstring flexibility and injury, there have been =
numerous published trials that seem to show that stretching and improved =
flexibility have no effect on hamstring injury. A number of authors have =
proposed that although no single aetiological factor can be identified, =
a multiple factor model may be more appropriate (real life!) .e.g. =
Strength, flexibility, warm up, fatique, technique/motor control etc. =
This obviously complicates matters and makes it more difficult to assign =
a quantifiable value to a specific activity. With regard to Hamstring =
Injury and the multiple factor model have a look at:
=20
Perrin, D.H., Worrell, T.W. Hamstring Muscle Injury: The influence of =
Strength, Flexibility, Warm-up, and Fatigue. Journal of Orthopaedic and =
Sports Physical Therapy, 16(1), 1992. The authors provide a =
further 11 references that support the importance of multiple factors =
over single factor aetilogy.
=20
At the end of the day, I think it very much comes down to the specific =
situation and individual. We all pretty much understand the physiology =
(& psychology:skill specific warm up, confidence etc?) of warming up, =
stretching etc, we need to relate that to the individual situation, time =
constraints, demands of situation and weigh up carefully the possible =
pro's and con's.
=20
On a purely personal note I do a skill specific warm up, stretch =
according to the demands of the activity (e.g. For Kickboxing I'll do =
quite a bit of stretching, whereas for mountain biking I'll do none) and =
usually (when time allows) integrate a cool down into the end of my =
activity (as opposed to a specific cool down) .
=20
Anyway, hope something can be salvaged from my rambling, I have to =
return now to be buried under my mounting pile of =
assignments...............who said students have an easy life?
=20
