INFLUENCE OF STIMULATED PLASTICITY TRAINING METHOD ON COORDINATION INDICATORS OF HIGH PEDAGOGIC EDUCATIONAL ESTABLESHMENTS’ GIRL STUDENTS

Purpose: study of stimulated plasticity training’s influence on coordination indicators of pedagogic HEEs’ girl students. Material: 264 girl students participated in the research. Experiment was being carried out during three years. Responding abilities, static and dynamic balance, orientation in space, promptness of operative thinking, volume of mechanical memorizing, distribution of attention, accuracy, quickness and of attention reswitching, accuracy of tasks’ fulfillment were assessed. Results: it was found that plasticity has different kinds and forms of manifestation. Creative motor tasks require different conditions for their realization. We determined rates of plasticity increment by its main kinds. Plasticity of body movements was achieved at high level of different muscular groups’ coordination, optimal rhythm, rational correlation of tension and relaxation. Conclusions: it was found that plasticity shall be trained in compliance with its kinds and manifestations. It requires appropriated approach to content of methodic of its perfection.


PHYSICAL EDUCATION OF STUDENTS
Girl students' accuracy was assessed with the help of the following tests: 1) accuracy of reproduction of set force value (with hand dynamometer); 2) accuracy of reproduction of set arms movements' amplitude (with kinematic meter of M. Zhukovskiy).
Responding abilities (dexterity) was assessed with the following tests: test for quickness of reaction (Catching of rule", S.A. Dushanin, 1978); 2) test for response to moving object.For this test computer program "Prognoz", worked out by Institute of physiology, named after A.A. Bogomolets, of Ukrainian AS was used.3) test for quickness of visual motor response (simple and complex) (test "Catching of stick" of I.V. Afanasyev, 2008); 4) complex coordination test, oriented on determination of exact, differently oriented speed-power movements for certain time (t computer program "Prognoz", worked out by Institute of physiology, named after A.A. Bogomolets, of Ukrainian AS, Kiev).
For estimation of ability to keep balance the following tests were used: 1) assessment of static balance (Romberg's test, "Stork" posture); 2) dynamic balance was estimated with test "Turns on gymnastic bench" (P.Khirts et al., 1985).
Results of the researches The methodic of plasticity training included complexes of motor tasks, mainly oriented on increment of some certain kind of it.Besides, we considered simultaneous impact of physical load on perfection of main characteristics of the studied coordination.For this purpose we used system of tests and assessment criteria [8,11,12,26].It permitted to sufficiently objectively measure the rates of plasticity increment by its main kinds.Great attention was paid to variability of muscular load, which was based on physical education program for pedagogic HEEs girl students.Wide usage of various physical exercises (as well as different conditions and means of their fulfillment, implementation of creative tasks) activated girl students' motor functioning, stimulated realization of their reserve potentials.In experimental groups all trainings were conducted with the help of play methods.Main attention was concentrated at development of body movements', upper girdle belt, lower limbs' and hands' plasticity.
To larger extent plasticity is intrinsic to junior age children.Natural plasticity disappears rather quickly, if it is not trained.For further its improvement special trainings are required.Materials of the research witness that usage of methodic of stimulated plasticity training permits to achieve increment of its indicators in girl students.Perfection of this coordination goes at different rates, depending on its kinds.
Analysis of body movements' plasticity did not show important differences between increment rates of experimental and control groups' girl students (see table 1).In stimulated training of upper limbs movements' plasticity rates of indicators' increment of experimental groups' girl students are ahead of control groups' indicators.It is connected with the fact that during rather long period of time girl students systemically fulfilled purposeful exercises.These exercises were oriented on training and strengthening of girdle belt muscles with simultaneous achievement of movements' expressiveness.Girl students were explained importance of the fulfilled exercises.Wide range of application of the received skills permitted to encourage interest to trainings.
Increment rates of hands movements' plasticity were lower in control groups.However, strengthening of small muscular groups with the help of special exercises and methodic permitted to sufficiently quickly influence favorably on development of this kind of plasticity.
Analysis of dynamic of indicators increment of lower limbs' movements showed average increment rates with natural and stimulated their development.It is connoted with gradual expansion of motor skills' range with fulfillment of different dance and choreographic exercises.Such exercises were the part of methodic of stimulated training of this kind of legibility and were characterized by higher dance fitness.
High mobility of nervous processes permits to quickly replace excitation processes by inhibition ones (alternate muscles' tension and relaxation).Application of special methodic ensured higher increment rates of the set posture plasticity in experimental groups' girl students The level of their physical condition permitted to keep the set posture during required time, which achieved by regular practicing of exercises' system of play and competition methods.It permitted to strengthen back muscles and articular ligaments.Such approach is the basis for mastering different postures with accurate distinguishing of muscular tension's character.It is a necessary condition of movements' beauty and plasticity.
To master such motor actions it is necessary to have sufficient coordination: dexterity, accuracy, mobility, rhythm.Large and variable fund of motor actions permits to easier muster and extrapolate qualitatively new motor acts, which require their emotional perception and reproduction.

Discussion
Body movements' plasticity was achieved with high coordination of different muscular groups, optimal rhythm, rational correlation of tension and relaxation.It manifested in such movements as turns, bents, rotations, squatting [7, 11, and 20].Different motor actions have specific means of expressiveness.For example, natural movements (run, jumps, throws) differ from gymnastic jumps, turns and acrobatic exercises.But all they have certain plasticity.That is why in the process of the research girl students' attention was accentuated on motor actions with maximal expressiveness, ease and grace.
Trainings' effectiveness is much higher with musical accompaniment [21,26,32].Character of movements can be transmitted with the help of tambourine, different sound signals and claps.With it attention is accentuated on preparatory movements and on main link of motor action.In training great role shall be played by visual analyzer, basing on fulfillment of exercises at mirror.It permits for gi rl students to independently assess fulfillment of exercise and compare it with standard as well as to correct it, if required.Such approach helps for girl students to find the reasons of mistakes.Other important methodic technique is application of visual bench marks [23,35].Girl students are keen for beauty and wish to reach it in music, art and dances.They start to see and understand it in movements.That is why girl students 'involvement in beautiful is an additional stimulus for them.Opportunity to enrich motor experience with new original movements at trainings increases girl students' interest.
Plasticity is a natural basis of aesthetic of any movements.It permits to transfer all gammas of feelings and emotions.Independent on difficulty of the fulfilled movement (simple step, jump, turn, dance movement) plasticity presents in all.At the dame time, plasticity manifestation depends on certain level of strength, quickness, endurance, dexterity, flexibility, mobility, accuracy.Depending on character and complexity of the fulfilled movement, different coordination qualities can be leading ones or additional [21,37].
When training sport movements' technique instructors do not pay attention to special training of plasticity.The main reason of it is insufficient scientific-methodic provisioning [8,30,34].That is why some instructors achieve girl students' high plasticity intuitively.Thus, it is necessary to develop natural plasticity and to improve them.Simultaneously it is required to educate girl students' strive for beauty.It will permit to assess any motor actions both by their technical complexity and by criteria of beauty.

Conclusions
Materials of our research showed that plasticity has different kinds and manifestations.Their improvement requires usage of various exercises.Creative motor tasks imply different conditions for their realization.For assessment of such tasks appropriate criteria are required.The received data witness, that plasticity shall be trained in compliance with its kinds and manifestations.It requires proper approach to content and methodic of its perfection.
Results of the research confirm that purposeful development of plasticity, considering its kinds and specific manifestations leads to improvement of its indicators with different increment rates.It positively reflected on physical fitness of experimental groups' girl students.At the same time the data of central nervous system's functional state improved.
In further publications we shall elucidate the methodic of stimulated training of girl students' other coordination qualities.
