How strong is the evidence for Foam Rolling?

Meta-analyses and systematic reviews of foam rolling and self-myofascial release consistently find modest short-term improvements in range of motion and some recovery-related performance parameters, without the flexibility loss sometimes associated with static stretching before exercise. That evidence is currently rated moderate (42/100), built on 9 published studies, including 3 randomized controlled trials and 1 meta-analysis -- a reasonable base, but not yet enough for full certainty.
