How many studies support Stretching?

Meta-analyses consistently and robustly confirm that both acute and chronic stretching improve range of motion and flexibility, with recent meta-regressions clarifying optimal dosing and the underlying neuromuscular and mechanical mechanisms. That's backed by 9 published studies in Vitaebase's database, including 9 meta-analyses, the most recent from 2025 -- a fairly substantial body of research for a single topic.
