TED-Ed: How stretching actually changes your muscles | Malachy McHugh

The video explores the role of stretching in preventing injuries and improving flexibility. It distinguishes between dynamic and static stretching, explaining how muscles, unlike rubber bands, are viscoelastic. Stretching affects muscle fibers and sarcomeres, temporarily enhancing flexibility. Long-term flexibility requires consistent stretching, which can also increase pain thresholds. However, excessive stretching can be harmful, and not all activities benefit from stretching. A tailored approach is necessary for different lifestyles.
