Investigation of the effect of differently constructed small sided games on the internal and external load parameters of football players

10 licensed male football players participated in this research. It was aimed to examine whether there is an effect on the internal and external load parameters, whether there is a difference between them and at what level if there is a difference, in the narrow field games that are structured in 3 different ways to the football players participating in the study. The study groups were formed with the participation of 10 licensed volunteer football players studying at the university in Istanbul. Three different narrow field games were applied to the participants. The effects of the applied narrow field games were examined with the GPS measurements used to determine the indoor and outdoor load parameters. These GPS parameters are; running distance, heart rate, acceleration and deceleration. According to the data obtained as a result of the study, the 5v5 narrow field game, 5v5 must press the line and the 5v5 miniature castle format narrow field games vary from internal and external load parameters, distance and speed parameters, workload and heart rate parameters, total parameters, speed parameters and maximum acceleration and acceleration. It was determined that there were positive effects on deceleration parameters (p<0.05). However, there were also differences between the parameters according to the narrow field games. As a result of the findings obtained from the study, it has been determined that footballspecific narrow field games have positive effects on internal and external load parameters, which are important for football players. As a result, it is possible to improve the performance elements of the athletes by using the training time more actively with the different narrow field games to be applied in the trainings and, accordingly, to achieve success individually and as a team.
