Science largely supports the idea that good mobility, defined as the ability to control a joint within a given range, is a pillar of musculoskeletal health.

Science largely supports the idea that good mobility, defined as the ability to control a joint within a given range, is a pillar of musculoskeletal health. Studies, such as systematic reviews on injury prevention in running (e.g., Lauersen et al., BMJ), confirm that strengthening and motor control work (often integrated through mobility) reduce the risk of injury. Regarding performance, the effect is more nuanced: while insufficient mobility can limit biomechanical efficiency, excessive flexibility is not systematically synonymous with better performance, as the body requires a certain degree of stiffness to store elastic energy (the spring effect). The assertion that mobility 'increases performance' is therefore partially true but simplified, as performance depends on a balance between mobility and stability. Finally, the direct link between mobility exercises and the immediate reduction of chronic pain is supported by observational and clinical evidence, although the response is highly individual. In short, the approach is sound, even if the benefit for pure performance is multifactorial.

What’s uncertain
Whether long-term stretching also changes muscle structure is debated; short-to-medium-term gains are mostly explained by increased stretch tolerance. Effects on injury prevention are modest and separate from flexibility gains.
