Perceptual-cognitive tasks play a pivotal role in performing voluntary movements, which is crucial for good performances among soccer players. This study explored the effect of perceptual-cognitive tasks on the inter-joint coordination of soccer players and college students during landing. The classic multiple objective tracking (MOT) task was used to simulate the perceptual-cognitive task under a sports environment. Fifteen soccer players (age: 20.1 ± 1.5 year, height: 181.4 ± 7.4 cm, weight: 75.4 ± 10.7 kg) and twenty ordinary college students (age: 20.0 ± 2.3 years, height: 177.9 ± 4.9 cm, weight: 71.6 ± 9.9 kg) were enrolled to the study. Participants in the two groups were subjected to a single task (landing task) and dual-task (MOT task and landing task). Coordination and variability indicators were recorded using a Vicon infrared motion capture system and a force measuring platform. The results showed that the mean absolute relative phase of hip and knee joint (MARP), deviation phase of hip and knee joint (DP), and deviation phase of knee and ankle joint (DP) of the two groups under the dual-task were significantly different compared with the parameters when participants were subjected to the single task. The dual-task had higher effect size on DP and MARP, indicating that dual-task had a greater impact on coordination of the hip and knee joints. DP and DP of ordinary students were more extensive relative to those of the soccer players, and hip joint stiffness ( ) for ordinary students was lower than that of the soccer players under the different tasks. These findings implied that the perceptual-cognitive task markedly affected the inter-joint coordination of soccer players and college students, mainly by impairing the hip and knee coordination. Although there is less variability in lower extremity coordination patterns of soccer players compared to college students, the MOT task still affects their coordination ability.
感知认知任务在执行自愿运动中起着关键作用，这对足球运动员的良好表现至关重要。本研究探讨了感知认知任务对足球运动员和大学生落地时关节间协调性的影响。经典的多目标跟踪（MOT）任务被用于模拟运动环境下的感知认知任务。招募了15名足球运动员（年龄：20.1±1.5岁，身高：181.4±7.4厘米，体重：75.4±10.7千克）和20名普通大学生（年龄：20.0±2.3岁，身高：177.9±4.9厘米，体重：71.6±9.9千克）参与该研究。两组参与者分别接受单任务（落地任务）和双任务（MOT任务和落地任务）。使用Vicon红外运动捕捉系统和测力平台记录协调性和变异性指标。结果表明，与单任务时的参数相比，两组在双任务下髋关节和膝关节的平均绝对相对相位（MARP）、髋关节和膝关节的偏差相位（DP）以及膝关节和踝关节的偏差相位（DP）均存在显著差异。双任务对DP和MARP的效应量更高，表明双任务对髋关节和膝关节协调性的影响更大。普通学生的DP和DP相对于足球运动员更为广泛，且在不同任务下普通学生的髋关节刚度（ ）低于足球运动员。这些发现表明，感知认知任务显著影响足球运动员和大学生的关节间协调性，主要是通过损害髋关节和膝关节的协调性。尽管与大学生相比足球运动员下肢协调模式的变异性较小，但MOT任务仍然会影响他们的协调能力。
