The purpose of this study was a comparative analysis of the physical development of armwrestlers with different levels of sports mastery applying the index method. Participants: 37 athletes were divided into 2 groups. Group 1 (n = 17, age - 18.94 ± 0.57 years), qualification – from beginners to 1 rank athletes. Group 2 (n = 20) age – 25.60 ± 1.10 years), qualification – from the candidate for the master of sports to the international master of sport.19 anthropometric indices were applied for the analysis. Results: average results dominated by body mass index. The athletes with a shoulder width index below the norm prevailed in group 1. Erisman index for the majority of participants in group 2 complied with the standards. The athletes with a strong body build prevailed by Pignet index. The average Livi index is set in 40-47% of athletes. All athletes had a hypersthenic body build by Vervek index. Qualified athletes demonstrated the significant increase in body mass index, shoulder width, Erisman index, Livi index, Vervek index, body surface and relative body surface, limb segment mass and conditional moments of the force of limb segments strength. It was impossible to determine any significant differences between the groups by power and vital indices. Conclusions: It was confirmed the effectiveness of the physical development analysis of armwrestling athletes by indexes. Qualified athletes are characterized by high index values demonstrated muscle development. The mass indices and conditional moments of force of the limb segments strength demonstrate the predictors of success. Keywords: Armwrestling; physical development; indices; sports mastery level.

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-to-hand 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.

The purpose of the work: study of students' mental workability with the help of different methodic and comparative analysis of the received results. Material: 40 students of 22–23 years' age (30 boys and 10 girls) participated in the research. We used battery of tests, which included Anfimov's tables, tapping test and audit tables by Kreppeling. Results: results of correcting test reflected stable state of mental workability in interval Monday-Wednesday with gradual decrease in the second half of week. Some links of functional system worked by different mechanisms (growth, stability, reduction). Against the background of low initial level of system's work it was assessed as formation of pre-nosological state. Conclusions: results of all tests shall be assessed as reflection of fatigue's gradual formation. Mental workability state is and indicators of functional state. It reflects imbalanced condition of regulatory mechanisms, characteristic for pre-nosological state.
