This study aimed to identify changes in tactical, physical and physiological performances in large-sided games during the preseason of elite footballers. Thirty professional football players participated in several GK+8vs.8+GK large-sided games across the first four weeks of the season. Players were monitored by GPS units and heart rate monitors to quantify physical, physiological and tactical performances. The variables were compared according to the preseason period, players' positioning and professional experience. The training situation promoted similar physiological responses during the first and the last training period. However, players were revealed to have higher levels of positional synchronization during the last preseason period, indicating an improved tactical performance. Tactical variables seem to reflect the improvement of players' performance during the preseason, measured in large-sided games situation, while affecting both physical and physiological demands. These results highlight the potential of positioning derived variables, concurrently to physical and physiological variables, for football training optimization.
本研究旨在确定精英足球运动员季前赛期间在大场地比赛中战术、身体和生理表现的变化。30名职业足球运动员在赛季的前四周参加了几场守门员+8对8+守门员的大场地比赛。通过GPS装置和心率监测器对球员进行监测，以量化身体、生理和战术表现。根据季前赛阶段、球员位置和职业经验对变量进行比较。训练情况在第一个和最后一个训练阶段促进了相似的生理反应。然而，在季前赛的最后阶段，球员们表现出更高水平的位置同步性，表明战术表现有所提高。战术变量似乎反映了球员在季前赛期间在大场地比赛情况下的表现提升，同时影响身体和生理需求。这些结果突出了与身体和生理变量同时存在的位置衍生变量在优化足球训练方面的潜力。
