Isometrics or Static Stretching for Runners?
Researchers look at most effective protocol for running prep.
Many runners don’t know that static stretching can impair athletic performance and increase injury rates (which is why it’s important for you to educate your clients who like to run). It may be worthwhile to examine isometrics which, in contrast, have more positive effects and less negative impact than static stretching.
While isometrics do not significantly improve sprint performance, isometric holds can stimulate weakened muscle groups to increase activity. This can be particularly beneficial for runners who have muscle imbalances.
More research is recommended to further understand specific exercises and hold times for maximum benefits. These findings are described in a review study in the International Journal of Exercise Science (2021; 14 (6), 1204–18).
