MODERN PROBLEMS OF PERFECTION OF ELITE LIGHT ATHLETIC SPORTSMEN’S TECHNICAL SKILLFULNESS PERFECTION

Purpose: perfection of elite sportsmen’s technical skillfulness in competition kinds of light athletic. Material: the data of more than 60 literature sources were systemized. Expert questioning of 36 coaches, having experience of work with elite sportsmen, was carried out; documents of training process planning were analyzed as well as sportsmen’s diaries (n=244). Results: we have presented main principles of sportsmen’s technical skillfulness perfection and elucidated characteristics of technical training methodic. We have determined main priorities of technical training building for light athletes at every stage of many years’ perfection. Dynamic of competition practice volume has been found as well as main requirements to selection of training means of technical orientation. The data of bio-mechanical criteria of sportsmen’s technical skillfulness assessment have been supplemented. Conclusions: effectiveness of sportsmen’s training methodic is determined by realization of previous stages’ technical potential in final competition results. It can be achieved by determination of means of and methods of different orientation rational correlation.

Introduction 1  At present time winter and summer calendars of events are still widening with increase of starts quantity by individual invitation of sportsmen-leaders of world rating.It permits to perform not less than in thirty competitions during years.Constant desire of high sports results stabilizes possibility of high results.It is connected with excessive nervous-psychic and physical loads, with worsening of technical fitness.All these result in reduction of efficiency in main competitions.Achievements of Ukrainian sportsmen-light athletes significantly lag behind from foreign during several years.
Results of performances at 30 th Olympic Games in Beijing (2008) and 31 st Olympic Games in London (2012), at world championships 2013 and 2015 showed main drawbacks in training of Ukrainian light athletes.They proved opinion of many specialists that existing system does not correspond to modern tasks of training of elite light athletes [4,5,6,25,35].
Light athletic is a kind of sports with complex coordination of motor structure and high dynamic loads.High level of world achievements sets difficult task before domestic specialists, which is connected with perfection of technical skillfulness of elite sportsmen.Every new step directly depends on special physical fitness, which is ensured by groups of exercises of different orientation [12,13,16,19,20].
Technical training requires fulfillment of great scope of exercises with different intensity.Training means shall facilitate perfection of required physical qualities and ability to use them in motor structure of competition exercise [16,26,30].
Selection of training means become more and more important.Achievement of higher sports results is connected with demand in fulfillment of such scope of training loads, which would ensure successful performance in one competition exercise.For this purpose it is necessary to use technical means, creating the basis for technical fitness.Such basis increase competition intensity of some characteristics of main exercise [15,24,26].
In spite of great practical experience and numerous works on training of elite light athletes, the questions of planning of technically oriented training loads in annual cycles have been regarded insufficiently.There has appeared demand in further perfection of traditional system of technical means and methods' application in annual training cycle, which would ensure high sports results in light athletic.
Considering specific character of the kind of sports and demand to effectively endure maximal load, some principles of methodic of technical means and methods' application in annual training cycle at stage of individual potentials' maximal realization, requires reviewing [14].

Purpose of the research, tasks, material and methods
The purpose of the research is perfection of elite sportsmen's technical skillfulness in competition kinds of light athletic.
The tasks of the research: 1.To study main problems of elite sportsmen's technical skillfulness perfection in light athletic at modern stage.2. To study specific features of elite sportsmen's technical skillfulness perfection methodic in light athletic.Material and methods: analysis and generalization of special scientific-methodic literature and documents; study and generalization of sports practice advanced experience; pedagogic observations.For further studying and solution of elite light athletes' technical perfection problem we fulfilled analytical review of scientific-methodic literature (more than 60 sources).The data about volumes of competition practice and technically oriented means at different stages of annual training cycle were generalized.At different stages of many years' perfection the data were insufficient.
At the last stage of the research we conducted analysis of practical experience of leading Ukrainian light athletic coaches: experts' questioning of 36 elite sportsmen's coaches; analyzed technical process planning and coaches' diaries (n=244).Besides, we determined optimal criteria of technical skillfulness assessment.
Results of the research Technical skillfulness shall be interpreted as perfection of motor component, rationality of technical structure and perfectness in their usage.With functional-structural approach to organization and control over motor actions it is evident that this concept is much wider.It includes structural-technical perfection of motor act and mechanisms of control and regulation of motor actions.All these ensure high final results.From position of requirements of sports actions' extreme mode technical skillfulness shall be understood as perfect mastering of the sports exercises' most rational motor structures with orientation at maximum in conditions of acute sports competition [10] Recent years great positive experience of technical skillfulness perception in light athletic has been accumulated [5,10,26].However, its dynamic requires searching new more effective ways of special technical fitness increase as well as physical qualities development.
At every stage of annual training there are definite tasks.At the beginning of preparatory period it is the task of restoration of already achieved best results of technical fitness.Then it is possible to pass to ensuring higher level of indicators, i.e. to perfection.In competition period of training the main task is maintenance of technical fitness level (which was achieved in preparatory period) and increase of technical and physical potentials' realization level.
At any stage of annual training cycle elite sportsmen's technical skillfulness is perfected in conditions of high intensity of fulfilled exercises.To avoid stresses it is necessary to constantly consider individual features and functional state of sportsman's organism.Besides, in weekly cycle it is necessary to alternate high volume of training work with moderate and low, using variation approach.
Main specific features of perfection of technical skillfulness include: 1) correspondence of means of muscles' local and regional development to main exercise by kinematic and dynamic characteristics; 2) correspondence of muscular work mode in perfection of technical actions to sports functioning; 3) definite correlation of volumes of main, special and special auxiliary exercises' fulfillment [17].

Fig.1. Main structural components of sportsmen's technical skillfulness
Main parameters of special exercises' correspondence to main and competition exercises are the following: -Power of push off, for which phase duration, force extreme and mean power of push off are the derivatives; -angle speed values of jerking leg's unbending joints and hip joint' bending joints of waving leg in push offs; -"zones of working angles" in joints of jerking leg in push offs, whose indicators are minimal joint angle and joint unbending amplitude (especially ankle and knee joints); -"coordination structure" of exercise, which shall be regarded, coming from demand in observation of the following principles: "dynamic balance", "conjugated development of physical qualities and sports technique's perfection", "functional correspondence of muscles' work when applying special training means" [5,7,11].

Discussion
Commonly accepted periodization of sports training, oriented on planned preparation of sportsmen to main starts of season [22, 27, and 29] was conditioned by competitions' system in1960 -1970.However, recent decade in light athletic calendar of events has significantly widened and total quantity of international competitions increased Level of sportsman's physical abilities The strongest Ukrainian sportsmen nearly do not perform in domestic competitions; they compete abroad in series of Grand-prize, "diamond League" and other competitions.If earlier the main purpose of training was to gradually prepare a sportsman for main starts of season, then, now, accent is made on readiness for high results' achievements in every competition.Sportsmen have to start in average at least once every 7-10 days.In spite of such great changes in calendar of events, traditional structure of annual training cycle construction has still been preserved [2, 19, 26, 33, and 36].
Modern ideas about laws of sports form achievement point at impossibility of its maintenance during all annual training cycle [6, 7, 23, and 37].Competitions of annual cycle shall be subordinated to achievement of peak of sportsmen's speed-power, functional, technical-tactic and psychological potentials by the moment of main competitions [28,32].
Specialists see solution of the problem in rational planning and distribution of competitions in annual training [28].When planning competitions in year it is necessary to consider unity of light athletes' training and competition loads in training system.Competition loads shall harmoniously coincide with dynamic of training ones and be an integral unit.Competitions of every training cycle's stage shall be in compliance with sportsman's fitness at definite stage of appropriate period.Sportsman's participation in competitions at different stages shall correspond to the level of his fitness and ability to solve the set tasks.At the beginning of summer competition season some commercial competitions are recommended.When preparing for main year's competitions starts are of preparatory character and have little psychic tension.Participation in great number of commercial competitions is recommended after Olympic Games and world championships.The existing at present rating system of results' assessment permits for light athletes, having high places in world rating, to participate in Olympic Games and world championships without preliminary selection.Elite sportsmen have opportunity to purposefully train for main year's competitions.The rest sportsmen shall show high results in selective competitions.
Usage of individually maximal training and competition loads is one of the most important principles of sports training, which ensure effective formation of long-term adaptation.There are two approaches, supplementing each other, depending on sportsmen's qualification and fitness, on stage on many years' training and period of training macro-cycle.
The first approach envisages even increase of volume and intensity of irritators that results in gradual strengthening of impact of sportsman's organism and planned formation of long term adaptation to impact factors.
The second approach is connected with sharp increasing of loads' volume and intensity and their high concentration in time.It is connected with deep mobilization of functional reserves of sportsman's organism.However, it creates preconditions for jump-like formation of adaptation processes [7, 28, and 29].
Experience of elite light athletes' training shows that in existing methodic of sportsmanship's perfection there is a number of organizational and methodic disadvantages: 1.There is no single opinion of practical specialists about main principles of conceptual apparatus of this field of knowledge.It inserts uncorrectable mistakes in strategy of training in the whole [18].
2. Important aspects of sports' techniques' rational examples in different kinds of light athletic have not been sufficiently studied in theory and practice.
3. In methodic provisioning of elite sportsmen's training process, in most kinds of light athletic main accents are made on increase of functional potentials.There are practically no special recommendations on methodology of technical skillfulness perfection.
4. There is excessive increase of mechanical work's volume.8.In connection with widening of calendar of events and demand in performances at the highest level for long time, the system of means and methods does not permit to maintain sportsmen's technical fitness for long period of time.
Intensification of elite sportsmen's technical training requires higher level of pedagogic control, which shall be conducted more carefully: from sportsmen's familiarization with new techniques, teaching to their elements and to perfection of technical skillfulness.Such control can be effective only if its structure will include biomechanical criteria as objective indicators of technical skillfulness level: volume, comprehensive character and rationality of technical training; effectiveness of techniques' mastering and skillfulness in it [9,18,34].
The received in our research results prove demand in searching of ways for sports' results' rising, connected with perfection of technical skillfulness [18,28,31,32].When assessing elite light athletes' technical skillfulness it is necessary to consider biomechanical characteristics, biomechanical criteria of motor techniques; level of sportsmen's fitness and indicators of competition functioning.
For further perfection of elite sportsmen's technical skillfulness in light athletic the most important is the search of highly effective means, which would correspond to biomechanical structure of main competition exercise.Conclusions 1. Technical skillfulness as system property of human motor function has multi-dimensional hierarchic structure.Its level can not be assessed by one of any listed indicators.Just because of this fact its perfection shall be approached from complex systemic positions.It well permit to increase the quality of Ukrainian light athletes' training to the greatest international competitions.
2. For noticeable increase of sportsmen's preparation for the greatest competitions it is necessary to solve all problems of their technical skillfulness perfection.
3. In light athletic not so the scope of loads as their skillful usage has decisive importance, as well as determination of training load's effective content, rational distribution of loads' volumes, selection of the most effective training means and methodic, their places in annual training cycle.
4. Effectiveness of elite sportsmen's training methodic is determined by realization of technical potentials of previous training stages in final result.It can be achieved by determination of rational correlation of multi-directional means and methods.Application of exercises, oriented on perfection of light athletes' high technical fitness, will be the most important.

To determine requirements to training means in process of elite light athletes' technical training.
. It is integral conception of theory and methodic of sports training.It is based on such fundamental concepts as sports technique and technical training.It is a result of development of definite light athletic effective technique and successful pedagogic process's application in technical training.Training of high quality results in high technical skillfulness of sportsmen.Such skillfulness ensures high probability of excellent results [3, 8].With it any competition result is an integral indicator of sportsmen's skillfulness.It as if integrates many of multidirectional factors of training (see fig.1).High technical skillfulness is a necessary condition of elite sportsmen's training.Development and perfection of technical training in many years' aspect can conventionally be divided into three stages: 1) choice of specialization and initial training; 2) formation of physical fitness and technique of the chosen light athletic kind, in which it is necessary to increase impact of training means on sportsman's organism; 3) development of physical qualities and technical perfection in the chosen light athletic kind, videlicet: further strengthening of technical means' impact on sportsman's muscular-skeletal apparatus [21].
31, and 38].It resulted in rising of density and duration of competition season.

In special technical training non-specific means, which lost training effect, are used.Prevailing role of special training means at stage of maximal realization of individual potentials, is conditioned by: 1) loss of informative value of comprehensive or special training means, i.e. reduction of their training effect in connection with sportsman's high workability; 2) reduction of fitness "transfer" with growth of organism's functional specialization, when non adequate means of any, even the highest intensity, do not give quantitative increment of the achieved special workability [7].6. Application of technical training means, which do not correspond to biomechanical structure of competition exercise, in training process [25].7. Application of technical training means, which do not facilitate realization of accumulated in competitions motor potential.
