The aim of the study was to examine the extent to which changing the game format (possession play vs. regulation goals and goalkeepers vs. small goals only) and the number of players (3 vs. 3, 5 vs. 5 and 7 vs. 7) influenced the physiological and physical demands of small-sided games (SSGs) in soccer in semiprofessional players. Fourteen semiprofessional male soccer players were monitored with global positioning system and heart rate devices. Heart rate, player load, distance covered, running speed, and the number of accelerations were recorded for 9 different SSGs. The results show that changes both in game format and the number of players affect the players' physiological and physical demands. Possession play places greater physiological and physical demands on players, although reducing the number of players only increases the physiological load. In the 7 vs. 7 games, changing the game format did not alter the heart rate responses. Finally, in the possession play format, changing the number of players did not produce significant differences in heart rate responses, although physical demands did decrease in line with a reduction in the number of players. These results should help coaches to understand how modifying different aspects of SSGs has a differential effect on the players' physiological and physical demands. Moreover, coaches in semiprofessional and amateur teams have now consistent information to design and optimize their training time in mixing the technical, tactical, and physical aspects.
本研究旨在探讨改变比赛形式（控球比赛与常规进球、使用常规球门与小球门）和球员人数（3 对 3、5 对 5 和 7 对 7）对足球半职业运动员小场比赛（SSG）中生理和体能需求的影响程度。14 名半职业男性足球运动员接受了全球定位系统和心率监测设备的监测。为 9 种不同的 SSG 记录了心率、球员负荷、跑动距离、跑动速度和加速次数。结果表明，比赛形式和球员人数的变化都会影响球员的生理和体能需求。控球比赛对球员的生理和体能要求更高，尽管减少球员人数只会增加生理负荷。在 7 对 7 比赛中，改变比赛形式不会改变心率反应。最后，在控球比赛形式下，改变球员人数不会对心率反应产生显著差异，尽管随着球员人数的减少，体能需求确实会下降。这些结果应有助于教练了解如何通过改变 SSG 的不同方面来对球员的生理和体能需求产生不同的影响。此外，半职业和业余球队的教练现在有了一致的信息，可以在混合技术、战术和体能方面来设计和优化他们的训练时间。
