Purpose: to determine the relationship between physical development and physical readiness among qualified wrestlers. Material & Methods: in the study involved thirty qualified wrestlers, aged 19–22 years. For the purpose of analyzing indicators of physical development and physical preparedness, pedagogical testing. Results: the results of the study testify to the homogeneity of the indices of physical development of the athletes under study, the coefficient of variation is in the range from 2,43% to 10,93%. It is revealed that the indices of physical readiness of qualified wrestlers are characterized mainly by small variation in the testing of speed-strength qualities, coordination abilities, general and strength endurance, and average – in the results of special endurance. Conclusion: it is determined that the most informative indicators of physical development are the weight of the wrestler’s body, which has a connection with 15 physical preparedness tests, followed by a vital index (12 statistically reliable relation-ships) and a strength index (11 interrelations).


Introduction
One of the most pressing problems of modern sports science is the search for effective ways to achieve high results provided that athletes develop harmoniously and maintain their health. A successful solution to this problem is significantly hampered by the intense professionalization of sports activities, a notable trend of increasing volumes and intensity of the load [6; 10].
Modern sports of higher achievements make high demands on all sides of the athlete's preparedness, in addition, the main problem of the sport of higher achievements is the impossibility of an infinite increase in training loads, which leads to the need for further searching for new, more effective pedagogical tools and methods in the system of training highly qualified athletes [1; 2; 9; 11].
The main source of information for the preparation of athletes for competitions is the complex control of their condition after the fulfillment of certain loads. The increasing importance of the methodology of comprehensive control of the preparedness of athletes and the management of the training process is due to many reasons that are typical for modern sport, among them: a significant complication of the system of training athletes; lagging the quality of complex control from the requirements for organizing sports training as a controlled process; increase in the number of measured indicators recorded during training and competitions; Increase of requirements to metrological maintenance of gathering and the analysis of the information on readiness of athletes [5; 7].
Relationship of research with scientific programs, plans, themes. The work was carried out according to the plan of research of the Kharkov State Academy of Physical Culture.
Purpose of the study: to determine the relationship between physical development and physical readiness among qualified wrestlers.

Objectives of the study:
-to reveal the level of physical development and physical readiness of qualified wrestlers; -to establish the degree of correlation between the indicators of physical development and the level of physical preparedness of qualified fighters.

Material and Methods of the research
Research methods: analysis of scientific and methodological information, generalization of best practical experience, pedagogical testing, methods of mathematical statistics.

Results of the research and their discussion
Based on the analysis of scientific and methodological information and generalization of best practical experience, it has been established that one of the main tasks of the wrestling training process is the development of physical qualities and the enhancement of the functional capabilities of the athlete's organism at all stages of long-term preparation [12].
Pedagogical testing was carried out for the purpose of analyzing indicators of physical development and physical preparedness. Table 1 presents the average indicators of the physical development of qualified Greco-Roman wrestlers.
For the homogeneity of sample observations, the coefficient of variation was used. It is believed that if the coefficient of variation does not exceed 10%, then the sample can be considered homogeneous [4]. The obtained data testify to the homogeneity of the indices of physical development of the athletes under study, since the coefficient of variation lies in the range from 2,43% to 10,93% (Table 1).
Physical training of wrestlers has its own specific features, which must be taken into account when constructing the training process and load distribution [3; 8]. It is necessary to observe the correspondence between the capabilities of the organism and the requirements presented to it when choosing the means and methods of training, therefore we used various methods of testing the coordination abilities, power endurance, speed-strength qualities, general and special endurance for assessing the physical preparedness of wrestlers. On the basis of these data, the indicators of the physical readiness of the qualified wrestlers of the Greco-Roman style were obtained ( Table 2).
The fluctuations of the mean group values of the indices of physical readiness of qualified wrestlers were estimated from the value of the coefficient of variation (V, %). Variability is considered small if the coefficient of variation is in the range from 0% to 10%, medium -from 11% to 20% and high -more 21% [4].
It is revealed that the indices of physical readiness of qualified wrestlers are characterized by predominantly low variability in testing the speed-strength qualities, coordination abilities, general and strength endurance, and the average in the results of special endurance. This gives grounds for the fact that in the training process of qualified wrestlers Greco-Roman style more time was devoted to the development of special endurance.
The informative nature of the relationship between physical development and physical readiness was determined by the method of correlation analysis (Table 3). According to the indicators of the table, the critical value of the sample correlation coefficient for the sample n=30 is equal to r=0,361.
The results of the study showed that the volume of the lungs has an average statistical relationship with the speed-strength abilities (suplex (r=0,37), climbing on a 5 m rope without the help of the feet (r=0,44), lifting the trunk from the supine position on the back for 20 s (r=0,39)); (endurance of the partner by the capture of the trunk from standing on parallel benches (r=0,44)) and general endurance (run 2х800 m (r=0,39)).
The life index has interrelations with the strength endurance in the tests: lifting the legs to the grip with the hands in the vise on the gymnastic wall (r=0,51), the maximum number of squats with the partner (r=0,40), the maximum amount of pull-ups (r=0, 43), the maximum amount push-ups (r=0,37), the partner's ascents by the trunk grip from behind, standing on the parallel benches (r=0,60); coordination abilities in the tests: running the "bridge stand" (r=0,43), 15 coups on the "bridge stand" (r=0,37); total endurance in the tests: run 800 m (r=0,54) and run 2x800 m (r=0,58) and special endurance (in the second (r=0,45), third series (r=0,57) and the sum of three series (r=0,51) of hip-roll).
The analysis of the left hand dynamometry indices revealed one statistically significant relationship with the first series of throws through the back (r=0,36), which characterizes the special endurance of wrestlers. Probably, qualified wrestlers play a crucial role in competitive actions on the right hand, so wrestlers in training sessions should pay attention to the strength of the left hand.

conclusions
The results of the study testify to the homogeneity of the indices of physical development of the athletes under study, since the coefficient of variation lies in the range from 2,43% to 10,93%.
It is revealed that the indices of physical readiness of qualified wrestlers are characterized by predominantly low variability in testing the speed-strength qualities, coordination abilities, general and strength endurance, and the average in the results of special endurance. This gives grounds for the fact that in the training process of qualified wrestler's Greco-Roman style more time was devoted to the development of special endurance.
The materials of the research showed that the most informative indicators of physical development are the weight of the wrestlers body, which has connections with 15 tests of physical fitness, followed by a vital index (12 statistically reliable relationships) and a power index (11 interrelations).
Next on the informative indicators are the body length and the Quetelet index, they have 9 reliable correlation links, then follows the age and the right hand dynamometry -6 statistically reliable interrelations, and the volume of the lungs -5 reliable correlations.
An analysis of the left hand dynamometry revealed one statistically significant relationship. Probably, qualified wrestlers play a crucial role in competitive actions with their right hands, so fighters in training sessions need to pay more attention to the strength of the left hand. further research will be aimed at determining the relationship between psycho-physiological indicators and the special physical preparedness of wrestlers.
