The aim of the study is to find the most efficient means to adjust the parameters of the physical effort in the football players aged 8 to 10 years according to the change of the cardiovascular indices. In this respect, a case study was organized for the specialists of football (coaches/teachers) from Romania and the Republic of Moldova. The research used the survey method according to the questionnaire developed in Google forms, consisting of 15 questions and transmitted online. The results of the sociological survey highlight the share of the training factors in different training periods of the football players aged 8-10, the time given to training and its components in various periods of preparation, also the content of the means used in the introductory part of the training session. There were identified the training mistakes that influence the most the recovery speed and/or the excessive training of the 8-10 years old football players. The weight of the cardiovascular indices used to adjust the physical effort parameters, the main influences of the football game on the physiological changes, the physiological indicators that determine the decrease of the game efficiency were also analyzed. The means and methods used to monitor and prevent the overtraining of the 8-10-year-old football players by adjusting the physical effort parameters in conformity with the changes of the cardiovascular indices led to an increased training efficiency. The implementation of a training plan based on the changes of the cardiovascular indices will contribute to the adjustment of the physical effort parameters in the 8-10-year-old football players.
