The Claim

Concurrent implementation of long-duration static stretching and resistance training is associated with substantial improvements in ankle dorsiflexion range of motion in highly trained individuals, with observed increases reaching approximately 25.9% over a 12-week intervention period, suggesting that adding prolonged stretching protocols to established resistance training regimens may enhance joint mobility without compromising existing training adaptations in experienced athletes.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If experienced athletes add long static stretching to their regular weightlifting routine, they can significantly improve how far their ankles bend without losing the strength or muscle gains they've already built.

  1. Study: The effect of a combined long‐duration static stretching and resistance training regimen on a competitive bodybuilder: A case study

    A single bodybuilder who added long stretching sessions to his weightlifting routine saw his ankle flexibility improve by about 26% over three months without losing strength. While this shows the combination works for him, more research is needed to confirm it works for everyone.
