Purpose: The main aim of our research was to determine the internal load of goalkeepers in the soccer training process. The internal load of goalkeepers during the training process is examined according to the achieved values of heart rate. Our goal was to expand the knowl-edge of the impact of different methodical forms on the goalkeepers’ internal load in soccer, thereby support the possibilities of improving their training process. The assumption was that the goalkeepers would achieve significantly different heart rate values in different methodical forms.<br />Methods: The research group was formed by six elite youth soccer goalkeepers (n=6) from U16, U17 and U19 categories. In order to evaluate the heart rate was used the POLAR PRO heart rate monitor and the loading zones of goalkeepers were determined by using a pro-gram called POLAR Team2. Subsequently, the obtained data were evaluated by using the Wilcoxon Signed-Rank Test and Cohen´s „r “(effect size).<br />Results: The average difference in HRavg during preparatory exercise and small-sided game was 25 ± 9 beats.min-1, and the average difference in HRmax was 35 ± 12 beats.min-1. During preparatory exercise achieved the goalkeepers’ value of HRavg 134 ± 8 beats.min-1 and in small-sided game was HRavg 159 ± 8 beats.min-1. In individual methodical forms were found significantly different average heart rate values (z = -2.201, p < 0.05, r = 0.9), which statisti-cally and logically confirmed our assumption.<br />Conclusion: Monitoring of soccer goalkeepers´ internal load in the process of training and improvement of game activities can greatly help the coaches in further planning, optimiza-tion and tracking of the training process. Based on our research´s results is recommended to monitor and evaluate the internal load intensity of goalkeepers using sporttesters during entire training process.
