[Stress-induced changes of attention during choking in judo].
The aim of the investigation is the registration and analysis of cognitive parameters in the alarm phase of the stress reaction during a conventional judo cross choking technique. 57 judoka (41 males, 16 females; mean age 23.1 +/- 6.7 years) underwent a standardized cross-choking maneuvre (juji-jime), which lasted for 6 - 8 s until giving up, carried out by a black belt physician. The Stroop inference test was performed before and twice after the intervention. The reading velocity of the interference task was reduced by an average of 77.4 s to a mean of 74.4 s (p < 0.01), and the number of reading errors decreased by a mean from 2.9 to 2.1 (p < 0.01), finally increasing to 2.4 s. The data show the most important improvement in performance in 25 s after choking in the male judoka. In the female judoka increasing performance started already 25 s before choking and continued 25 s after the intervention. The alarm reaction following the potential life threatening stressor with an attack upon the throat improves selective attention before (female subjects) and after choking (female and male subjects) depending on gender.
