Not really. At least not according to a study titled “Impact of stretching on the performance and injury risk of long-distance runners” which concluded, among other things, that:
- Static stretching can reduce running economy and performance for up to an hour afterwards
- Static stretching doesn’t reduce the longevity or intensity of DOMS (delayed onset muscle soreness)
- Static stretching doesn’t do much for chronic injuries
- On average elite athletes are less flexible than their non-elite counterparts
Kind in mind the study only addresses static stretching. Dynamic stretching is something I do before every run.
