众所周知，运动时的注意力会影响表现；然而，基于虚拟现实 (VR) 的锻炼所固有的注意力需求尚不清楚。我们使用双任务范例来比较基于 VR 和非 VR（传统的、现实世界）锻炼的注意力需求：22 名老年人（没有诊断出残疾）以平衡的块顺序执行主要到达虚拟和真实目标的任务，同时在三分之一的试验中对意外的听觉音调进行口头反应。主要到达任务的注意力需求是从声音响应时间（VRT）到听觉音调推断出来的。参与者的参与水平和任务经验也是通过问卷获得的。虚拟目标条件比真实目标条件更需要注意力（VRT 明显更长）。二次分析揭示了参与水平和目标条件对注意力需求之间的显着交互作用。对于高度参与的参与者来说，注意力需求很高并且与目标条件无关。然而，对于那些参与度较低的人来说，注意力需求较低，并且取决于目标条件（即虚拟>真实）。这些发现为越来越多的有关老年人技术增强运动的开发和应用以及康复目的的研究增添了重要的知识。
Attention during exercise is known to affect performance; however, the attentional demand inherent to virtual reality (VR)-based exercise is not well understood. We used a dual-task paradigm to compare the attentional demands of VR-based and non-VR-based (conventional, real-world) exercise: 22 older adults (with no diagnosed disabilities) performed a primary reaching task to virtual and real targets in a counterbalanced block order while verbally responding to an unanticipated auditory tone in one third of the trials. The attentional demand of the primary reaching task was inferred from the voice response time (VRT) to the auditory tone. Participants’ engagement level and task experience were also obtained using questionnaires. The virtual target condition was more attention demanding (significantly longer VRT) than the real target condition. Secondary analyses revealed a significant interaction between engagement level and target condition on attentional demand. For participants who were highly engaged, attentional demand was high and independent of target condition. However, for those who were less engaged, attentional demand was low and depended on target condition (i.e., virtual > real). These findings add important knowledge to the growing body of research pertaining to the development and application of technology-enhanced exercise for older adults and for rehabilitation purposes.
