A vote for tolerance
Does stretching increase range of motion by changing the physical characteristics of soft tissues (“plasticity”)… or our neurological tolerance for elongating it? It’s one of those surprisingly basic body mysteries. Here’s a fresh new data point in the plasticity vs. tolerance debate, from Konrad et al:
The increased range of motion could not be explained by the structural changes in the muscle-tendon unit, and was likely due to increased stretch tolerance possibly due to adaptations of nociceptive nerve endings.
