Flexibility & Injury Prevention
topic
The relationship between flexibility and injury prevention is more nuanced than commonly assumed — with optimal injury prevention requiring adequate flexibility (sufficient tissue extensibility to accommodate athletic demands) combined with adequate stability and strength through that range of motion (mobility rather than passive flexibility alone). Excessive passive flexibility without muscular control (hypermobility) actually increases injury risk in some joints, while the more common deficit — insufficient range of motion at the hip, thoracic spine, and ankle — forces compensatory movement at adjacent joints that are not designed for those demands.
Role
Flexibility and injury prevention literacy corrects the over-simplified 'more flexible = less injury' belief that drives stretching practices focused solely on flexibility increase without the concurrent strength development through range of motion that produces injury-protective mobility. The gymnast with extreme passive flexibility who lacks the muscular control to stabilize those positions is more, not less, injury-prone than the normally flexible athlete with controlled range of motion. Most injury prevention programs address the deficit of inadequate flexibility without addressing the equally consequential deficit of inadequate strength through range — leaving half the injury prevention prescription unaddressed.
