Introduction: The study of athletes' psychophysiological characteristics is one of the major problem at sports science. The aim of the study is to perform comparative analysis of athletes' power and adaptive capacities during the implementation process of controlled activity, like performing screen-selection activity. Materials and methods: In research participated divided into 3 groups martial arts athletes: taekwon-do ITF and karate WTF (n=34); Greco-Roman and freestyle wrestling athletes (n=18); sambo and judo athletes (n=11). As a device, a tablet of Apple company - iPad, fourth-generation, with 9,7-inch screen was used. For the heart rate (HR) registration it was used BT4.0&ANT+ Heart Rate Monitor. Participants performed a sample: the response rate of the selection. The attempt was to react to one given signal from the five proposed. Results: Taekwon-do ITF athletes, karate WTF, hand-tohand combat showed the best reaction selection time rates. The worst reaction selection time rates were shown by Greco-Roman and freestyle wrestling athletes. Conclusions: The handled comparative analysis reaction time of selection for athletes of different kinds of martial arts has verified its high informative value. Taekwon-do ITF, karate WTF, hand-to-hand combat athletes have better results. The results suggest that participants' state of adaptiveness was normal. The high informative value of used test allows recommend it as screening in the selection of promising athletes to the combat martial arts which mostly emphasize striking techniques.
