Relevance of the research problem. Sport is a value of every nation, which includes the system of physical, spiritual and cultural education, sports achievements, scientific knowledge, international communication (Karoblis, 2005). High level sport is inseparable from competitive activities, the pursuit of sports results (Hargreaves & MacDonald, 2000; Karoblis, 2005). The special training of athletes in the chosen sports is a part of general education of personality, which has a close connection with social, educational, political, economic issues of humanity development (Johnson et al., 2007). The athlete training process is a multi-year educational process of a specific structure and organizational form, which develops physical characteristics of an athlete, determines his activity, behavior, independence and responsibility, promotes to achieve excellent results. However, optimization of athlete training technology, construction of training system and its filling with full content still have the greatest impact on the improvement of sports results (Bompa & Buzzichelli, 2018; Karoblis, 2005; Платонов, 2004). Management of high-performance athlete training is related to prognostication, individual model characteristics of sport fitness, general and special load ratio, search for new effective directions of workout methodology, modeling of competition activity indicators, workout process planning, competition program conclusion, sport training adjustment (Karoblis, Raslanas, Steponavičius, 2002). Track-and-field athletics is integral sports that combine cyclic and acyclic exercise competitions: running, throws, vertical and horizontal jumps (Armonavičius, 1995). Short distance running is one of the most prestigious track-and-field athletics competitions. An exceptional short distance motor feature is the maximum intense activity of the whole body, especially the nervous and muscular systems, lasting from 0.1 to 40–50 s (Stanislovaitis et al., 2008). The ever-improving sports results reveal new human mental and physical abilities, vast resources of the body that could not even be dreamed of before. The organization of exercise, methodology, their scope and intensity, their combination with the means of recovery according to the main laws of phenotypic adaptation form the basis for the training of high-performance athletes (Платонов, 2004; Stonkus, 2000; Issurin, 2008; Krylovas, Kosareva, Dadelienė, & Dadelo, 2020). The particularity of the sport is based on competition. The results recorded in sport receive global recognition and become a true human achievement standard. In the world, they are constantly progressing, promoting the development of the sport community, therefore the greatest human intellectual and material resources are directed to the training of high-performance athletes (Skernevičius, 2015; Krylovas, Kosareva, Dadelienė, & Dadelo, 2020). However, the results of a research conducted by scientists showed that over the past nearly 20 years, elite athletes, including Olympic, world champions and prizewinners, have achieved personal best results in key competitions of the season by only in 50 percent cases (Yakimovich & Ovchinnikov, 2016). This shows that the opinion that contemporary coaches are high-performance and knowledgeable in the training of elite athletes and immaculately control and manage the process of sport training of athletes is not sufficiently substantiated. It has been established that the development of high-performance sprinters depends on many factors, the most important of which is the directionality of the training process, its management, taking into account the individual characteristics of the athlete's body adaptation to workout and competition loads (Stanislovaitis, 2008; Бондаренко, 1999; Нбанекова, Филин, 1995). The training of sprinters and their competitive activities have been extensively studied not only by foreign (Smith, 2005; Doscher, 2009; Kale & Bayrak, 2009; Prins, Murata, Derenne, Morgan, & Solomon, 2010; Dickin, Reyes, & Dolny, 2009; Nelson, Landin, Young, & Schexnayder, 2008; Eikenberry, Mcauliffe, Welsh, Zerpa, Mcpherson, & Newhouse, 2008; Oзoлин, 1986), but also by Lithuanian sport scientists (Stanislovaitis, 2008, 2006, 2005; Grūnovas, 2006; Butkus, 2006, 1995; Skurvydas, 1999, 2003; Bradauskienė, 2006). Although the world record of female sprinters in a 100 m distance is quite high (10.49 s), the search for new training methods and their application in the process of female sprinter workouts continues. Scientists are not only analyzing and evaluating existing workout methodological tools, but also looking for new methods for an advanced sprinter training process. Thus, in search of new methods to increase running speed, through more research and the application of the latest training technologies, methods can be discovered to help athletes to become faster and to develop a running speed, which has never been achieved before. Recently, in a 100 m running, as in many track-and-field athletics competitions, the results of athletes are progressing rapidly. That progress depends heavily on the selection of talented athletes, scientifically and practically sound and effective workout methodologies, the selection and application of remedial measures, the material compensation of athletes, which greatly increases motivation of athletes, and etc. Therefore, in order to achieve good results and prizes in high rank competition in contemporary sport, it is necessary to know the peculiarities of the application of training methodology, to properly select the most important starts of the annual training cycle, taking into account all conditions at the place and time of competition. An athlete and a coach must not only follow the innovations of training methodology, science and medicine, but also look back, be able to analyze his own results and the results of athletes, who have shown significant results theretofore, the peculiarities of workout tools and methods applied by them, the reasons for successful and unsuccessful starts, and then all this to apply to the management of his own training process. Discovering, revealing and learning about new technologies through the theory and didactics of sport workout is the most important function of sport science (Mester, 2003), and it is important for a coach to be able to use scientific results and recommendations, be insightful and be able to successfully model the training of elite athletes (Karoblis, Raslanas, Poteliūnienė, Steponavičius, Petkus, & Žilinskienė, 2011). The purposeful training of female sprinters and the search for effective technologies in order to increase the maximum running speed become a scientific problem. The presented scientific problem is relevant for the following reasons: ● It is important to analyze the change in results in terms of age and to determine the age, at which the highest results are achieved; ● It is important to research and theoretically substantiate, which components determine the sports result in short distance running; ● To research the effectiveness of training measures in order to increase maximum running speed; ● The contribution of running at maximum speed to the sports result in a 100 m run has not been sufficiently researched; ● It is important to establish criteria that affect the progress of athletes' mastery and the change of sport performance. Hypothesis. It is likely that sports results of female sprinters are not improving due to the integrated and concentrated training models applied separately. A universal speed training model is more effective. Object of the research is the process of female sprinter training. Aim is to identify the peculiarities of optimizing the training of high-performance female sprinters. Objectives of the research: 1. On the basis of the data of the theoretical analysis of scientific sources, to reveal the change of the results of high-performance female sprinters in terms of age. 2. To perform a comparative analysis of the preparation of high-performance female spriners for the Athens, Beijing, London and Rio Olympic Games. 3. To review the technologies of sports training of female sprinters and to examine the factors influencing their results. 4. To determine the effectiveness of a universal method for training the speed of high-performance female sprinters. 5. To reveal/identify the opinion of high-performance female sprinters about the factors determining their training system. Theoretical and practical significance Researching the structure and content of sports training for female sprinters of different ages and sports mastery, analyzing the change of sports results in terms of age, evaluating workout methods, running speed components, the provisions for effective running speed increase were identified: ● Running speed is determined by the speed of muscle contraction, the length of leg support, the frequency of steps, and the sports result in a 100-meter run depends mainly on the maximum running speed. ● In order to improve the results of the maximum running speed of female sprinters, it is important to apply a universal, combined method in the workout process, running with weight and stretching with an elastic band. These provisions are relevant to the theory and practice of female sprinter training. The results of the study can be used in the development of training programs for sports schools and high-performance female sprinters. CONCLUSIONS 1. The age for achieving the best personal result in the women's 100 m running competition is 24.69 ± 3.27 year. The best Lithuanian sprinter L. Grinčikaitė-Samuolė achieved her best result in this running competition at the age of 25 – 11.19 s. At the beginning of their athletic career, American sprinters had the highest running scores and dominated until the age of 17, however later is observed leadership of the Caribbean Region female sprinters up to the age of 35. The results of European sprinters were average in almost all age groups. 2. Analysis of the four Olympic Games revealed a significant improvement in the results of the 100 m running and starting reaction speed (p < 0.05). In order to get to in the 100 m running final, athletes should run an average of 10.96 ± 0.03 s, and to become the prizewinners of the competition – 10.86 ± 0.08 s. Sprinters become the prizewinners of the 100 m run at the age of 25.42 ± 3.18 year. 3. Lithuanian female sprinters lose to the best sprinters of Europe and the world in the competition requiring the maximum running speed – 40 m in acceleration (11.99 %). The best Lithuanian sprinter L. Grinčikaitė-Samuolė reduces this difference to 4.05 % in the 100 m running distance, the gap between Europe's and the world's best female sprinters is gradually declining due to improved European sprinters' maximum running speed results. 4. The resisted/assisted running method is the most effective way to increase the running speed and starting acceleration, as this speed training method significantly improves the values of step length and support duration than running normally. 5. High-performance female sprinters lack attention to an important component of training – psychological training – in the process of their sports training. It was found out that their sports training and improvement of results are more influenced by external (monetary prizes, premiums) than internal motives (desire to improve results, honor to represent their country). A coach's personality also has impact. The coach is valued not only as a specialist, but distinguishing his personal qualities, such as sincerity, friendliness, motivation, promotion is considered an integral part of the training process.
