ResumoThe emergent nature and dynamics of Task-Related Thoughts (TRT) during accumulated physical effort was used to test a model of attention focus based on the application of nonlinear dynamic systems theory (NDST). A one-group two-trials quasi experimental design was employed. Eleven physically active participants ran twice on a treadmill at an intensity of 80% of their HRmax until voluntary exhaustion. During the first run their intrinsic dynamics of attention focus was established. Accordingly, during the second run they were asked to intentionally maintain Task-Unrelated Thoughts (TUT), and reporting back about spontaneous switches from TUT to TRT, and vice versa. Results revealed that the intentionally imposed TUT was stable at the beginning of the test, switched spontaneously to TRT with accumulated effort, competing with TUT and showing metastability, until a final TRT state prevails. The observed phenomena points to a nonlinear dynamic self-regulation of attention focus during accumulated effort.
