I don't understand how this relates to what we were talking about, stretching was the topic. It doesn't relate to athletes either, there's studies showing that doing the same exercise standing up and lying down only helps with the position you trained in, I'd expect that to be the same with this vertirun. I'd expect it to cause injuries in athletes more than anything, you're avoiding working the hamstrings eccentrically and a lack of eccentric hamstring strength is known to be the biggest risk factor for hamstring injuries.
