Model characteristics of anthropometric indicators of Juvenile category athletes in acrobatic rock ’ n ’ roll ( preliminary preparatory stage )

Acrobatic rock’n’roll is a pair sport, in which, when selecting a sports couple, you should take into account the weightgrowth index of the male partner and female partner [2; 5; 6]. This is especially important at the initial stage of the formation of a sports couple. When preparing athletes for acrobatic rock’n’roll at the stage of preliminary basic training, it is important to find the optimal weight-growth index that will correspond, as much as possible, to the technique of conducting in pairs, to the sensation of the partners of simultaneous performance of basic and choreographic exercises in the competition composition of this category. In the future, with the increasing technical skill of the male partner and female partner in the performance of the basic dance technique and the transition to a different age category where acrobatic elements are used, the optimal selection of a sports couple and their weight-growth index play a big role in the indicator of the sport result [1; 3; 4].

On this basis, it is important to have an idea of the optimal difference in weight-growth rates between a male partner and female partner.

Objectives of the study:
1. To analyze the sources of special scientific and methodological literature on the research problem.

Material and Methods of the research
Research methods: theoretical analysis and generalization of data from special scientific and methodological literature, methods of mathematical statistics.The study involved 20 sports couples (20 male partners and 20 female partners) of an acrobatic rock'n'roll category Juvenile aged 10-14 years.it possible to establish that the selection of a sports couple (female partner, male partner) in acrobatic rock'n'roll at the stage of preliminary basic training is of great importance in their competitive activity [2; 5].

results of the research and their discussion
The analysis of the weight-growth index of the Juvenile category athletes from acrobatic rock'n'roll gives grounds to state about the importance of the optimal difference in weight-growth rates between the female partner and male partner (Table 1-3 ence the technique of pairing, the feeling of partners during synchronous performance of basic and choreographic exercises in the competitive composition of this category, and also influence the technique of performing acrobatic elements in the transition of sports couples to the second age group. Based on the obtained results of the study, model characteristics of anthropometric indices of the Juvenile category athletes in acrobatic rock'n'roll (Table 4).prospects for further research will be directed to the development of model characteristics of special physical and technical preparedness of athletes of acrobatic rock'n'roll category, Juveniles aged 10-14 years.

SlobozhanSkyi herald of Science and Sport
At the moment, we have not found any publications on the study of anthropometric indicators of the Juvenile category in acrobatic rock'n'roll.In this regard, one of the current problems in acrobatic rock'n'roll is the lack of model character-istics of the anthropometric indicators of the athletes of the category Juvenile of this sport.relationship of research with scientific programs, plans, themes.The work is carried out in accordance with the Consolidated Plan of research work in the field of physical culture and sports for 2016-2020.On the topic: "Psychosensory regulation of motor activity of sportsmen of situational sports" (State registration number 0116U008943) the purpose of the research: to develop model characteristics of the anthropometric indicators of the Juvenile category in acrobatic rock'n'roll.

conclusions 1 .
As a result of the weight-growth study of the Juvenile category in acrobatic rock'n'roll, the pair selection model.2. Developed model characteristics can be used for an optimal selection of a partner and partner in a pair, and also for optimization of the training process of athletes at the stage of preliminary basic training.
