Static Stretching and Human Movement: An Integrative Narrative Review of Tissue Mechanics, Neuromechanical Responses, and Functional Performance

Static stretching reliably improves joint range of motion (ROM), but its consequences for human movement are less consistent. This integrative narrative review examines acute and chronic responses across seven domains: ROM and flexibility, passive tissue mechanics, force and strength, power and stretch–shortening cycle function, jump performance, landing biomechanics, and balance or postural control. Structured searches in PubMed, Scopus, and Web of Science supported publication-level evidence mapping and targeted source verification; no new meta-analysis was conducted. ROM gains may reflect increased stretch tolerance, reduced passive stiffness, or both, and do not independently demonstrate structural tissue adaptation. Passive mechanical responses vary across tissues, protocols, and measurement approaches. Acute static stretching can transiently reduce maximal strength, particularly after longer exposures, whereas chronic interventions show small average strength gains supported by low-certainty evidence. These findings do not establish comparable improvements in mechanical power or complex movement performance: pooled chronic jumping effects are trivial, and landing and balance responses remain heterogeneous, with limited chronic landing evidence and uncertain static-stretching-specific balance effects. The proposed framework relates joint mobility and passive tissue mechanics to neuromechanical measures and task-specific outcomes, while distinguishing observed responses from hypothesized cross-domain pathways. Neuromuscular and sensorimotor processes and contextual factors guide interpretation without establishing neural mediation or uniform moderation. Functional changes must therefore be assessed within the intervention and task tested. Concurrent multilevel measurements and longitudinal analyses are needed to determine whether changes in one domain contribute to outcomes in another.
