Svysch Y. Development of track-and-field sprinters' speed and power qualities with application of artificial hypoxia.

Object - is the track-and-field sprinters special physical preparation; purpose - is to perfect the special physical preparation of track-and-field sprinters with application of artificial hypoxia; methods: theoretical analysis and generalization of the scientific and methodical literary data and the materials of empiric research, pedagogical observation, pedagogical experiment, some methods of empiric data receiving, mathematic statistic methods; novelty - for the first time it is set that application of artificial hypoxia ( 15-25 minutes in the mode of breathing 3min. ? 3min.- 5min.? 5min. with content О2 12-14%) during 8 microcycles of setup time causes reliable growth of speed-power qualities development level and physical capacity of track-and-field sprinters; for the first time it is proven that more protracted (more than 8 microcycles) application of artificial hypoxia does not conduce to the same results; for the first time it is discovered that express-application of artificial hypoxia causes better speed-power qualities development, promotes physical capacity of sprinters, who used it regularly (at preparatory period), comparing to those sportsmen who applied it for the first time; knowledge about the model indexes of physical development, speed-power preparedness of athletes-sprinters is enlarged; efficiency of application of exercises of hypoxia character in the speed-power kinds of sport is confirmed; results - the efficiency of introduction of the eleborated author's program are proved, practical recommendations for professionals in sport brunch and for trainers of track-and-field are elaborated, results of the conducted researches are inculcated in practice of skilled athletes-sprinters and can be used under time of teaching of general theory of preparation of sportsmen in the specialized educational establishments; field - physical education and sport.
