Research on the reactivity/adaptation of players to the specific effort in performance football

Abstract

Performance football is playing with increasing intensity and that is why the purpose of the research was to check a system for evaluating the individual characteristics of the reactivity level/adapting the players to the specific effort, on the team positions, to optimize the preparation and recovery. We considered that we can identify techniques and instruments, devices and research facilities by using which can be made a diagnosis of the level of reaction and adaptation of football players, specialized in different positions, players involved in the national league's competitive system, to the specific effort in training and competitions. In order to verify the hypothesis and achieve the purpose of the research, we conducted a pilot study with the C.S. Internațional Bălești team, the third league, in 2017, in the second period of preparation and competition, we selected and used the following tools for objective evaluation of the spectra circumscribed to the theme: Polar system, heart rate, load level, calories burned, lactate GPS data, to determine the level of lactic acid in the blood, the Gacon test to evaluate the aerobic power of the subjects (VO2 Max) and a motor test to determine the lactacid speed capacity. Based on the sports diagnosis made at the beginning of the pilot study with the instruments/tests used, the specific effort was directed in the preparatory, precompetitive and competitive stages of the players, on playing positions, with the application of the principle of individualization and at the end of the research I found, based on the same evaluation tools, improvement of time at the lactacid speed test due to the power training preceded by the maximum force weekly, which led to increases in start, acceleration and deceleration power; significant improvement of lactic acid tolerance, due to weekly lactacid speed training, but also improved number of repetitions and implicitly aerobic power, in the Gacon test, as a result of weekly VO2 Max development training.
