The police forces performance is demanding on well-timed and quick reaction. Single reaction time and choice reaction time are crucial when the jeopardy appears. Performing under stress in life-threatening situations needs a good level of stress tolerance. In our study, we used two nonspecific, and two specific (shooting) tests to analyse the reactivity of police officer under different conditions. Material and methods: The research sample consisted of n=18 male Czech police training instructors. The group is unique as these police officers are specialised in the professional self-defence with focus on the coercive means use and shooting skills. Two standardized non-specific tests administrated with the Vienna Test System (VTS) by Schuhfried GmbH were used for data gathering. Single reaction time (SRT) was measured by the Reaction test, stress tolerance and choice reaction time (CRT) was measured by the Determination test. Two practical non-standardized shooting tests were used for the reactivity analysis in the goal oriented environment (shooting range). Results: The single reaction time among police training instructors was M=261.56±33.60 ms, which corresponds to the 66.28 percentile of age norm. Performance in the stress tolerance test also matches the average performance in population (M=45.56 percentile of correct reactions, M=61.67 percentile of incorrect reactions, M=51.44 percentile of skipped signals). According to the Pearson correlation coefficient, there is no correlation between single reaction time in the Reaction test and choice reaction time in the Determination test (r=-0.03). There is no correlation between single reaction time in the nonspecific Reaction test and performance in the specific Shooting test 1 (r=0.06) and Shooting test 2 (r=-0.01). Conclusions: There is no relation between the results in the specific and non-specific reaction tests. Nonspecific tests of single reaction time and choice reaction time are suitable for a general assessment of motor abilities. Specific tasks need specific training and specific evaluation methods.

A scientific framework for this study is the Humanistic Theory of Martial Arts, and the psychology of sport using the concepts of goal, task and success. The problem and aim of this study was an explanation of “perception of success” in groups of adults practising martial arts. Is perception of success influenced by the respondents’ social background or the type of martial art practised? Would there be any differences in results depending on their country of origin and residence, and if so, what results? The research was done within the framework of the IMACSSS.1A/2011: “Social determinants of participation in martial arts schools and clubs”. The tool was Perception of Success Questionnaire, which was used to survey a number of respondents from the United States, the Czech Republic and Poland, who were selected randomly and participated voluntarily. The statements and calculations have been ranked by more or less contact forms of martial arts. The results obtained in this study indicate a poor relationship between perception of success and the type of fighting style practised and a measurable relationship between the perception of success and social origin. There is a weak relationship in perception of success by respondents from American or European cultures.
