The purpose of this study was to investigate the relationship of any error (delta; ∆) between the image of one's own walking rhythm and the actual walking rhythm and physical activity, as a new motor imagery assessment.
The subjects were classified into two groups: a high activity group (HA-Group) having high physical activity with less than four hours of sitting time per day, and a low activity group (LA-Group) having low physical activity with more than four hours of daily sitting time. Visual rhythm, auditory rhythm, mental comfortable walking rhythm, and mental maximum walking rhythm were used to assess new motor imagery. Their beats per minute were measured and any error (delta; ∆) from the actual rhythm was calculated: ∆ visual rhythm, ∆ auditory rhythm, ∆ mental normal gait rhythm, and ∆ mental maximal gait rhythm.
When comparing the two groups, the HA-Group had significantly higher ∆ visual rhythm, lower ∆ auditory rhythm, higher ∆ mental comfortable walking rhythm, and lower ∆ mental maximum walking rhythm ability than the LA-Group. Furthermore, in an ANCOVA with age, ∆visual rhythm, and ∆auditory rhythm as adjustment factors, the HA-Group had significantly lower ∆mental maximum walking rhythm than the LA-Group.
These results showed that the rhythmic assessment of the imagery of maximum walking was associated with stationery time. It is possible that the more inaccurate the imagery of maximum walking, the longer the sitting or lying time.
本研究旨在探讨作为一种新的运动想象评估方法，个人行走节奏的意象与实际行走节奏之间的任何误差（δ；∆）与身体活动的关系。
将受试者分为两组：高活动组（HA组），身体活动量高，每天坐姿时间少于4小时；低活动组（LA组），身体活动量低，每天坐姿时间超过4小时。使用视觉节奏、听觉节奏、心理舒适行走节奏和心理最大行走节奏来评估新的运动想象。测量每分钟的节拍数，并计算与实际节奏的任何误差（δ；∆）：∆视觉节奏、∆听觉节奏、∆心理正常步态节奏和∆心理最大步态节奏。
比较两组时，HA组的∆视觉节奏显著更高，∆听觉节奏更低，∆心理舒适行走节奏更高，∆心理最大行走节奏能力低于LA组。此外，在以年龄、∆视觉节奏和∆听觉节奏作为调整因素的协方差分析中，HA组的∆心理最大行走节奏显著低于LA组。
这些结果表明，最大行走意象的节奏评估与静息时间有关。最大行走意象越不准确，坐着或躺着的时间可能就越长。
