概括

在行走时听有声书并没有影响健康年轻人的步态参数. 然而,在罕见和频繁的听众之间观察到步态阶段和压力的差异,这表明"姿势第一"的策略.

关键词:
认知表现 认知表现这是一种双重任务.双重任务的成本是双重任务.步行参数 步行参数一个单一的任务.在跑步机上行走,在跑步机上行走.

科学领域:

  • 生物力学 生物力学
  • 神经科学是一个神经科学.
  • 人类运动科学科学 人类运动科学

背景情况:

  • 听觉刺激的影响,如音频书,在行走过程中对步行表现的影响是研究不足的.
  • 音频内容越来越受欢迎,需要了解其对日常活动 (如行走) 的影响.
  • 现有的研究表明,在双重任务场景中,一种"姿势优先"的策略可以实现步行稳定,这种策略可能会因认知任务优先级而改变.

研究的目的:

  • 为了研究在空间时空步行参数上,在走路时听一本有声书的影响.
  • 在模拟的日常生活双重任务条件下评估步行表现.

主要方法:

  • 40名健康的年轻人参与了这项研究.
  • 时空步态参数在单任务 (行走) 和双任务 (在听有声书的同时行走) 条件下在跑步机上5分钟测量.
  • 关键参数包括步行阶段,最大压力和双重任务成本,统计分析.

主要成果:

  • 尽管主观认知负载很高,但在单任务和双任务步行之间没有发现空间时空步行参数的显著差异.
  • 在参与者之间观察到步态阶段和最大压力的显著差异,他们的听力习惯不同.
  • 罕见的听众表现出更短的立场阶段,更长的摆动阶段和更高的主导脚跟压力,双重任务成本有显著差异.

结论:

  • 在健康的年轻人中,作为双重任务,在听有声书的同时走路并没有改变时空步行参数.
  • 在这个群体中,观察到的罕见和频繁的听众之间的差异可能支持"姿势优先"的策略.
  • 个人倾听习惯可能会影响双重任务行走期间的步态调整.
