Here's a classic example of a study the media will distort beyond all utility.

Stretching does not live up to its reputation as an injury preventer, a study has found.

"We could not find a benefit," said Stephen Thacker, director of the epidemiology program office at the federal Centers for Disease Control and Prevention in Atlanta. Athletes who stretch might feel more limber, but they shouldn't count on stretching to keep them healthy, he said.

Then, at the end of the story, we find:

Other research has found that warming up can reduce the risk of injury. Gymnasts and dancers might be exceptions because their activities require great flexibility, so stretching might help them, Thacker said.

There you have it, stretching is both beneficial and not beneficial. Whatever.
