Purpose: The SpeedCourt system has been confirmed as an effective and dependable tool for evaluating multi-directional change-of-direction (COD) maneuvers. It has also been employed in the rehabilitation process following Anterior Cruciate Ligament (ACL) injuries and for multi-directional training purposes. This study investigated by means of the SpeedCourt system determines 1) whether there is any difference in COD parameters and countermovement jumps (CMJ) between United Arab Emirates (UAE) and non-UAE professional footballers 2) whether there is any difference between the two lower limbs during change-of-direction manoeuvres.
Methodology: This analysis included 100 professional football players from UAE or Non-UAE football clubs who were tested at FIFA Medical Centre of Excellence. With the help of Speedcourt system, 6-s tapping, countermovement jump (CMJ) and chase 15-s tests were performed. Comparison was done between UAE and non-UAE footballers and also between the dominant and non-dominant sides.
Results: Out of the 100 players, 83 players were right foot dominant. Apart from the countermovement jump test, there was no significant difference in results between UAE and non-UAE football players. Average time to turn for dominant and non-dominant sides did not show any significant difference, for either group.
Conclusion: There is no difference in 6-s tapping, Chase 15-s tests or limb asymmetry amongst UAE and Non-UAE footballers. However, the non-UAE footballers showed significantly better performance in Countermovement Jump Test. The data provide baseline values for forthcoming sports medicine research, which can be taken into account when creating injury prevention or return-to-sport protocols, particularly with regard to change of direction parameters and countermovement jump.

SpeedCourt 系统的实用性：对阿联酋迪拜国际足联卓越医疗中心的 100 名职业足球运动员进行的新颖研究

目的： SpeedCourt 系统已被证实是评估多向变向 (COD) 动作的有效且可靠的工具。它还被用于前十字韧带 (ACL) 损伤后的康复过程以及多向训练目的。本研究通过 SpeedCourt 系统进行调查，确定 1) 阿拉伯联合酋长国 (UAE) 和非阿联酋职业足球运动员之间的 COD 参数和反向移动跳跃 (CMJ) 是否存在差异 2) 两者之间是否存在差异改变方向动作时的肢体。
方法：本次分析包括 100 名来自阿联酋或非阿联酋足球俱乐部的职业足球运动员，他们在 FIFA 卓越医疗中心接受了检查。在Speedcourt系统的帮助下，进行了6秒的攻丝、反向运动跳跃（CMJ）和追逐15秒的测试。对阿联酋和非阿联酋足球运动员以及主导球队和非主导球队之间进行了比较。
结果：在 100 名球员中，83 名球员右脚占主导地位。除了反跳测试外，阿联酋和非阿联酋足球运动员的结果没有显着差异。对于任何一组来说，主导方和非主导方的平均转向时间都没有显示出任何显着差异。
结论：阿联酋和非阿联酋足球运动员的 6 秒敲击、Chase 15 秒测试或肢体不对称性没有差异。然而，非阿联酋足球运动员在反向运动跳跃测试中表现出明显更好的表现。这些数据为即将进行的运动医学研究提供了基线值，在制定损伤预防或重返运动方案时可以考虑这些基线值，特别是在方向参数的变化和反向运动跳跃方面。
