Abstract

This study investigates if lower extremity open-skill training impacts perception and cognitive processing abilities or just influences task related motor abilities. Twenty-two participants (24.7 ± 2.4years; 11 males, 11 females) were randomly allocated either into the group that trained on a computerized device or to the control group. Prior to and following the 4-week study period, motor performance was assessed using drop jump, hexagon test, postural control and lower extremity choice reaction. Perception, cognitive processing and task inhibition were captured using validated neurocognitive tests. Repeated measurements analyses of co-variances (ANCOVAs) were performed. They revealed a time (before and after intervention) × group (training vs. control) effect on lower extremity choice reaction and hexagon (p < .05). No effects on group differences or between groups in cognitive performance were found. A detrimental effect of training on accuracy of task inhibition (lower percentage of correct inhibitions) was detected. Computerized open skill training affects specific movement patterns without increasing task-relevant cognitive or perceptual abilities. Indicated by the lower percentage of correct inhibitions, the training might further detrimentally influence the risk-taking behavior during choice reaction tasks.

下肢开放技能训练对视觉刺激感知、认知处理和表现的影响

摘要

本研究调查下肢开放技能训练是否影响感知和认知处理能力,或仅影响与任务相关的运动能力。22 名参与者(24.7 ± 2.4 岁;11 名男性,11 名女性)被随机分配到计算机设备训练组或对照组。在 4 周研究期之前和之后,使用跌落跳跃、六边形测试、姿势控制和下肢选择反应评估运动表现。使用经过验证的神经认知测试来捕获感知、认知处理和任务抑制。进行了协方差 (ANCOVA) 的重复测量分析。他们揭示了时间(干预前后)×组(训练与控制)对下肢选择反应和六边形(p< .05)。没有发现对组差异或组间认知表现的影响。检测到训练对任务抑制的准确性(正确抑制的百分比较低)的不利影响。计算机化的开放式技能训练会影响特定的运动模式,而不会增加与任务相关的认知或感知能力。正确抑制的百分比较低表明,训练可能会进一步不利地影响选择反应任务期间的冒险行为。
