The use of computer technologies at an assessment of sensory-motor reactions in single combats

. purpose: to develop a complex of program applications by an assessment of sensory-motor reactions of sportsmen who are engaged in different types of single combats. Material and Methods: theoretical analysis and generalization of scientific and methodical literature, method of computer programming. results : the computer program applications by an assessment of sensory- motor reactions of sportsmen-wrestlers are developed and the preliminary approbation of appendices is carried out, their metrological informational content is confirmed. Conclusions: during the approbation the received results confirm the data on characteristic values of the level of psychomotor reactions of sportsmen which are available in literature. it allows recommending the developed computer applications for a practical use.

3. Assessment of a simple acoustical motor reaction (SAMR). 4. An assessment of reaction of a choice among static objects. 5. An assessment of reaction to a moving object (RMO).
6. An assessment of feeling of speed. 7. Assessment of reaction of distinction, reaction to a dynamic object. 8. An assessment of reaction of a choice from two dynamic objects. 9. An assessment of force of nervous system (Tepping-test). 10. A time sense assessment, both with a use of sound intervals, and light. The program applications including the above-named test tasks are developed in the Swift programming language and calculated on a use on tablet computers with the operating system iOS [13].
The preference to these tablets and the operating system were caused by their speed, reliability, technical characteristics and simplicity of communication with the user.
The interface of all developed programs is simplified and consists of two operating buttons "Start" and "Reset" (pic. 1).

All tests are developed in one style, and the process of testing is carried out in the automatic mode. The testing technique practically of all tests includes the offer to the examinee to execute 12 attempts, and after the implementation of the test the program selects 10 best results, calculates an arithmetic average, defines a normality of distribution of the received results according to the criterion of Shapiro-Wilk and, at the compliance of data of the law of normal distribution, suggests to keep result in a database (pic. 2).
At the unsuccessful implementation of the test it is offered to pass it repeatedly. No more than one minute is on average spent for the implementation of the test.
More than 50 sportsmen who are engaged in different types of single combats (fight, taekwondo, karate) having qualification from 1 category to the master of sports of the international class (MSIC), various age (from 16 till 22 years old) took part in a preliminary approbation of the developed applications. As the tested the tablet computer iPad of the 4th generation was used.
Results on some tests (SVMR -simple visual motor reaction, SAMR -simple acoustical motor reaction, RMO -reaction to a moving object) are presented in tab. 1. note. SVMR -is a simple visual motor reaction, SAMR -is a simple acoustical motor reaction, RMO -is a reaction to a moving object.
The given results in the tab. 1 and the results received by us according to other tests confirm the data which are available in literature [5; 7; 11] on characteristic values of the level of psychomotor reactions of sportsmen. It allows recommending the developed computer applications for a practical use.

Conclusions:
1. The analysis of special literature confirmed the relevance and the importance of a problem of an assessment of psychomotor reactions at sportsmen, and also defined the directions of improvement of a technique of preparation in single combats taking into account a functional condition of psycho-physiological functions at a sportsman.
2. The test tasks for an assessment of psychomotor reactions of sportsmen of single combats including the tasks according to simple and difficult motor reaction, and also the tasks according to specific perceptions, such as feeling of speed, time sense are selected.
3. The computer program applications by assessment sensory-motor reactions of sportsmen of single combats are developed and the preliminary approbation of appendices is carried out, their metrological informational content is confirmed.
Prospects of further researches. The further research will be directed on an approbation of appendices on tablet computers of other models, the question of transfer of appendices on smartphones and their optimization according to technical capabilities of mobile devices, import and export of databases to cloudy storages with possibility of their further use is also considered.
