The Claim

High-intensity static stretching increases stretch tolerance, measured as passive torque at end-range dorsiflexion, in young men over a four-week period, whereas low-intensity stretching fails to produce significant adaptations in this neuromuscular parameter, indicating that higher discomfort levels during stretching training promote central nervous system adaptations that allow greater joint angles without altering underlying muscle-tendon mechanical properties.

In plain English

Doing intense static stretches for a month makes your body more comfortable with being stretched further, mainly because your brain and nerves get used to the discomfort rather than your muscles actually changing. Light stretching doesn't trigger this response, so you won't see the same flexibility gains.
