Methodic of speed endurance development by professional soccer players

OBJECTIVE The characteristics of competitive loads in professional soccer present that speed endurance abilities are among the main factors for sucsess in the game. The high level of these abilities during the whole year is one of the most important problems in management of training process. The aim of this research was to establish a method for the development of speed endurance abilities and realize it in annual training program by professional soccer players. METHODS The methods of the research were: literature review; modeling; experiments; HR changes and blood LA concentration measurements; control testing; conventional mathematical methods of data systematization. Subjects were 23 professional soccer field players from PFC "ZCKA" - Sofia, Bulgaria with 26 + 4 years old. RESULTS The example of structure of weekly training program, which included interval trainings, was presented on Table 1. The example of dynamic of some of control test parameters, measured by Vame Vall test, was shown on Table 2. Total time of loads increased from 17 + 0.4 min to 18 + 0.5 min, or stabilization of maximal HR level from 196 to 198 beats per min during the test. Increasing of speed endurance abilities reflected positive over the match results of PFC "ZCKA" - Sofia in year 2006. In period from 20.08.2006 to 15.10.2006 the team played 18 games of which 15 were won.
