The cognitive demand required for a range of locomotor tasks has been described for a variety of populations. However, the effect of different training strategies on the cognitive demand required while learning novel locomotor tasks is not well understood and may inform physical rehabilitation. The authors examined whether two training strategies, gradual and sudden training, influenced the cognitive demand required while practicing a novel locomotor task, asymmetric split-belt treadmill walking. Simple reaction times and whole-body kinematics were recorded throughout practice. Gradual training resulted in significantly lower reaction times during much of training, suggesting that gradual training is less cognitively demanding than sudden training, possibly due to a reduction in error feedback or movement planning demands.
一系列运动任务所需的认知需求已针对多种人群进行了描述。然而，不同训练策略对学习新运动任务时所需认知需求的影响尚未得到充分理解，而这可能为身体康复提供参考。作者研究了两种训练策略，即渐进式训练和突然训练，是否会影响练习新运动任务——不对称分带跑步机行走时所需的认知需求。在整个练习过程中记录简单反应时间和全身运动学数据。渐进式训练在大部分训练过程中导致反应时间显著降低，这表明渐进式训练在认知上的要求低于突然训练，这可能是由于错误反馈或运动规划需求的减少。
