research done on rats shows that a hypertrophied muscle is more elastic and
will tear if submitted to abnormal range of motion stretching much latter
than control rats muscles.
If you have any references stating that a stretching program must be
implemented in addition to full range weight training to avoid flexibility
losses please send it to this group.
Anyway muscles contract and "stretch" while engaged in any dynamic phisical
actvity such as weight training. The degree of the stretch ocurring is
determined by the range of motion used in the exercises.
Otherwise the effect of "exclusive" use of "partial range" of motion
strength exercises on flexibility would be an interesting issue to be

Agreeded, and very big muscles could for some joints possibly limit room for
movment, not due to a non flexible state of the muscle, but due to a
reduction in free space, now ocuppied by big muscles. This can be seen in
some very big lifters which barely can do full squats or some bodybuilders
which cant touch their shoulders with their hands due to a very big biceps
and forearm muscles.
Also thanks Andrew for your references list
