科学领域:

  • 呼吸系统生理学 呼吸系统生理学
  • 认知神经科学 认知神经科学
  • 人类表现的人类表现.

背景情况:

  • 呼吸障碍在各种健康状况中很常见,并且可以影响视觉注意力等认知功能.
  • 了解呼吸困难对认知任务的影响对于管理身体活动至关重要.

研究的目的:

  • 调查吸气值负荷 (ITL) 和相关呼吸障碍如何影响视觉注意力.
  • 用多重物体追踪测试 (MOT) 在不同启发负载条件下评估视觉注意力.

主要方法:

  • 一个测试前后测试设计用于25名健康的年轻成年人 (19-31岁).
  • 参与者执行单一 (MOT) 和双重任务 (MOT + ITL在20或40厘米H2O).
  • 视觉注意力 (MOT分数),呼吸障碍强度 (博格尺度) 和情绪反应 (SAM) 被测量.

主要成果:

  • 与单个MOT相比,ITL的双重任务降低了MOT得分,中等负载 (40厘米H2O) 导致更大的缺陷.
  • 呼吸障碍的强度和负面影响在ITL和双重任务期间增加.
  • 较高的MOT得分与更大的灵感肌肉力量和积极影响相关.

结论:

  • 启发性负载和呼吸障碍会降低视觉注意力准确度,而较高的负载,较弱的启发性肌肉和更大的情绪困扰会放大效应.
  • 在体力活动评估和治疗计划中,应考虑呼吸障碍引起的认知干扰.
  • 一种物理认知方法来规定身体功能可能会改善日常活动的表现.
