SPEED ENDURANCE CHANGES IN FOOTBALL PLAYERS OF DIFFERENT INDIVIDUAL DEVELOPMENT AT STAGES OF ANNUAL PREPARATION CYCLE
The sequence of the study aimed at determining the level of speed endurance development in the players of groups for improving sportsmanship, and, subsequently, an amateur football club, depending on the characteristics of the physique and the period of training in the annual cycle during several sports seasons, is outlined. The purpose of the study is to increase the effectiveness of sports training of football players of various somatic types through the development of their (football players) speed endurance, through taking into account changes in its indicators at the stages of the annual cycle. Achieving the goal became possible using the following methods: analysis of scientific and methodological sources, pedagogical observations, pedagogical testing, somatometry, somatotyping, mathematical and statistical processing of the results. To assess the level of development of speed endurance, the control exercise "40-second shuttle run" along a 20-meter "segment" was used. Somatometry and somatotyping were carried out according to the method of three-level somatodiagnosis by R.N. Dorokhova, V.G. Petrukhina (1990). Statistical processing of the study results was carried out using standard mathematical procedures. The results of the study were obtained on the same contingent of football players for several sports and seasons, and their (results) analysis made it possible to conclude that the division of football players into groups according to body type showed their uneven distribution; the change in indicators that determine the level of development of speed endurance in the experimental athletes depended on their belonging to a particular somatic type; the dynamics of speed endurance of football players is connected not only with their somatic type, but also with the period of training process in the annual training cycle.
