It's really only static stretching for long periods of time (like I think it was 60s for those studies).
But yeah, there's some decrease and may be significant. but if people stay healthier or move better because of it then it works.
The effects go away after about 30 minutes too. So if someone is warming up 30 minutes before a workout then you can add it in before then.
