I think that the title is only somewhat misleading. When I think of "stretching" I think of the classical static stretching which is increasingly coming under fire.
I grew up calling dynamic stretching "warm ups".
I think this is probably true for most people, but I admit that it may depend a lot on the fitness environment one grew up in.
The article actually means static stretching. I grew up knowing the difference and used dynamic stretching[1] pre-explosive events and static stretching at off-times.
