Relations between daily stressful events, exertion, heart rate variability, and thoracolumbar fascia deformability: a case report.

Background: The posture of performance-oriented sport climbers adapts in a way that likely promotes the development of low back pain. The thoracolumbar fascia, while also contributing to performance, seems to be involved in that process. Furthermore, there has been evidence of the stiffening of the fascial structures in disorders associated with negative affectivity.
