> The present study was designed to investigate the effects of
> a cross-choking-technique commonly used in Judo on visual
> acuity. In 156 Judokas, experienced in competition, visual
> acuity was examined before and after choking (Juji-Jime). The
> average age of the 46 female and 110 male subjects was 22.8
> years (standard deviation 10.5 years). In all examined grades
> of distance (infinite, 0.55 m and 0.4 m), eye tests showed an
> improvement of visual acuity after choking on a highly
> significant scale. In quantitative terms, vision the far
> sight range was optimized more clearly than in the close
> ranges. The following mechanisms are discussed as possible
> causes of the present results: an increase of blinking
> frequency induced by stress, an optimized tear film covering
> the cornea, a stenopaeic gap induced by improved blinking,
> pupillomotor alterations and an improved cerebral processing
> of visual signals and information. From an evolutionary-
> biologic perspective, the benefit of this psychophysiological
> mechanism might consist in an improvement of visual acuity in
> moments of danger, approaching from a distance and, thus,
> better chances of survival.
