“…This may be only true for visual stimuli, as for auditory stimuli no gender related differences in the evoked gamma response were observed (Karakaş et al, 2006). This finding is in concordance with findings on the behavioral level indicating a female superiority in perceptual speed, the ability to rapidly absorb the details of a visual stimulus, which has been recognized since the 1940s (e.g., Harshman, Hampson, & Berenbaum, 1983;Kim & Petrakis, 1998;Tyler, 1965;Wesman, 1949) and generalizes to many types of visual stimuli.…”

“…Superior anticipatory skills (Mori et al, 2002), and a faster visuoperceptual speed (Kim and Petrakis, 1998) also arise from the comparison between different skill levels. Furthermore, a comparison of techniques has also been studied (Sforza et al 2000;Gulledge and Dapena, 2008), as the force at impact (Girodet et al, 2005).…”

a b s t r a c tThe aims of this study were: (i) to present the kinematic and electromyographic patterns of the chokuzuki punch performed by 18 experienced karatekas from the Portuguese team, and (ii) to compare it with the execution of 19 participants without any karate experience. The kinematic and electromyographic data were collected from the arm and forearm during the execution of the specific punch. A two-way analysis of variance (ANOVA) was used with significant level set at p 6 0.05. We found that the kinematic and neuromuscular activity in this punch occurs within 400 ms. Muscle activities and kinematic analysis presented a sequence of activation bracing a near-distal end, with the arm muscles showing greater intensity of activation than muscles in the forearm. In the skill performance, the arm, flexion and internal rotation, and the forearm extension and pronation movements were executed with smaller amplitude in the karate group. Based on the results of this study, the two groups' presented distinct kinematic and electromyographic patterns during the performance of the choku-zuki punch.

“…Testimonies from the participants confirm that long-term training significantly influences the reduction of anxiety not only before and during kumite, but also in everyday life [29]. It is a fact that the offensive approach is most widely used in tactical preparation, and it characterizes the athletes with efficient attention processes, thus providing fast and accurate reactions to spatial and visual stimuli [19,[30][31][32][33] and with extraordinary sensory and motor performance in relation to the speed and power during kumite [34][35][36][37].…”

This text represents a research that by individual treatment explores the influence and effect of the so-called advanced karate training (combined training program for development of physical and mental skills) in strengthening the person's tolerance to difficult and stressful situations. The aim of the research was to achieve optimal performance by the athletes during the kumite 1 in karate. The research involved initial, control and final experiment, where the karate practitioners were focused on the training model given (group; n = 13) and working in a group with additional individual intensive sessions provided for each participant. All athletes were male contestants aged 26.4 ± 6.8. The aim of the research was to explore how their performance can be influenced using psychological techniques during karate trainings, or how not to fall into one of the four undesirable states of mind called Shikai 2 .Results confirmed that the model of combined physical and mental training for athletes improves their physical skills and optimizes performance during competitions.
