title: [Sexual dimorphism of the psychophysiological indices in sportsmen of higher qualification].
abstract: To determine the influence of sexual dimorphism on mental characteristics in elite athletes, 24 sportsmen (18-27 years old) (17 men and 7 women members of Ukrainian National Judo Team), 20 sedentary men and 20 sedentary women (20-29 years old) were studied. Results obtained confirmed significant difference of sexual dimorphism indices in athletes and sedentary people. It was determined that sexual dimorphism manifestations in athletes were as follows: (1) short memory capacity (62.58 +/- 3.21%) and coefficient of operational thinking (2.67 +/- 0.16 standard units) was increased in women in comparison with men (55.78 +/- 2.07% and 1.44 +/- 0.30 standard units, p < 0.05, accordingly), (2) on the contrary neurodynamic functions were decreased in women (latent time of simple (266.92 +/- 4.73 ms) and composite (494.44 +/- 6.38 ms) visual-motor reactions and power of nervous processes (18.49 +/- 8.93%) in comparison with men (239.62 +/- 5.26 ms, 440.10 +/- 6.61 ms, 5.33 +/- 0.59%, p < 0.05, respectively). Results obtained indicate influence of sexual dimorphism on psychophysiological functions.
