Stretching Can Be Part of a Warm-Up, but Injury Prevention Is a Different Question
Stretching can increase range of motion, but evidence does not establish that a stretch before one workout protects against injury in that session.

Muscle injury classification distinguishes structural tears from functional disorders, so pain or dysfunction alone does not establish a tear.
Terminology for muscle problems in sport has historically been inconsistent, particularly for terms such as “strain.” The Munich consensus was developed to distinguish muscle-related conditions more clearly and improve consistency in research and clinical communication .1
That classification distinguishes functional muscle disorders from structural muscle injuries. Functional disorders involve muscle-related symptoms without macroscopic evidence of a fiber tear, whereas structural injuries involve macroscopic damage such as partial tears or (sub)total tears and tendinous avulsions .1
The distinction means that muscle pain or dysfunction should not automatically be described as a structural tear. In sports injury surveillance, researchers also need explicit definitions and classifications so that muscle injuries can be recorded and compared consistently across studies .1,2
