The ability to track multiple objects plays a key role in team ball sports actions. However, there is a lack of research focused on identifying multiple object tracking (MOT) performance under rapid, dynamic and ecologically valid conditions. Therefore, we aimed to assess the effects of manipulating postural stability on MOT performance.
Nineteen team sports players (soccer, basketball, handball) and sixteen sedentary individuals performed the MOT task under three levels of postural stability (high, medium, and low). For the MOT task, participants had to track three out of eight balls for 10 s, and the object speed was adjusted following a staircase procedure. For postural stability manipulation, participants performed three identical protocols (randomized order) of the MOT task while standing on an unstable platform, using the training module of the Biodex Balance System SD at levels 12 (high-stability), eight (medium-stability), and four (low-stability).
We found that the ability to track moving targets is dependent on the balance stability conditions (F = 8.7, < 0.001, η² = 0.09), with the disturbance of postural stability having a negative effect on MOT performance. Moreover, when compared to sedentary individuals, team sports players showed better MOT scores for the high-stability and the medium-stability conditions (corrected -value = 0.008, Cohen's d = 0.96 and corrected -value = 0.009, Cohen's d = 0.94; respectively) whereas no differences were observed for the more unstable conditions (low-stability) between-groups.
The ability to track moving targets is sensitive to the level of postural stability, with the disturbance of balance having a negative effect on MOT performance. Our results suggest that expertise in team sports training is transferred to non-specific sport domains, as shown by the better performance exhibited by team sports players in comparison to sedentary individuals. This study provides novel insights into the link between individual's ability to track multiple moving objects and postural control in team sports players and sedentary individuals.
在团队球类运动中，跟踪多个物体的能力起着关键作用。然而，目前缺乏对在快速、动态和生态有效的条件下进行多目标跟踪（MOT）性能的研究。因此，我们旨在评估操纵姿势稳定性对 MOT 性能的影响。
19 名团队运动参与者（足球、篮球、手球）和 16 名久坐者在三个姿势稳定性水平（高、中、低）下进行 MOT 任务。在 MOT 任务中，参与者必须在 10 秒内跟踪 8 个球中的 3 个，物体速度根据阶梯程序进行调整。为了操纵姿势稳定性，参与者在不稳定平台上使用 Biodex Balance System SD 的训练模块，以 12 级（高稳定性）、8 级（中稳定性）和 4 级（低稳定性）执行三个相同的 MOT 任务协议（随机顺序）。
我们发现跟踪移动目标的能力取决于平衡稳定性条件（F = 8.7，<0.001，η²= 0.09），姿势稳定性的干扰对 MOT 性能有负面影响。此外，与久坐者相比，团队运动参与者在高稳定性和中稳定性条件下表现出更好的 MOT 分数（校正值= 0.008，Cohen's d = 0.96 和校正值= 0.009，Cohen's d = 0.94；分别），而在更不稳定的条件（低稳定性）下，两组之间没有差异。
跟踪移动目标的能力对姿势稳定性水平敏感，平衡干扰对 MOT 性能有负面影响。我们的结果表明，团队运动训练的专业知识可以转移到非特定的运动领域，正如团队运动参与者与久坐者相比表现出更好的运动表现。本研究为个体跟踪多个移动目标的能力与团队运动参与者和久坐者的姿势控制之间的联系提供了新的见解。
