We herein report an experimental study examining the potential positive effects of Virtual Reality (VR) feedback during an indoor bicycling exercise. Using a regular bike coupled to a VR system, we compared conditions of no VR feedback, VR feedback and VR feedback with the presence of a virtual coach, acting as a pacer. In VR feedback conditions, we observed a decreased level of perceived exertion and an increased level of enjoyment of physical activity, when compared to a regular exercise situation (no VR feedback). We also observed a shift in the subjects' attentional focus, from association (in the absence of VR feedback) to dissociation (in VR feedback conditions). Moreover, the presence of a virtual coach in the VR environment triggered a systematic regulation of the (virtual) displacement speed, whose relationship with perceived enjoyment and exertion require further work.
我们在此报告一项实验研究，该研究考察了室内骑自行车运动期间虚拟现实（VR）反馈的潜在积极效果。我们使用一辆与VR系统相连的普通自行车，比较了无VR反馈、VR反馈以及有虚拟教练作为配速员的VR反馈这几种情况。在VR反馈条件下，与常规运动情况（无VR反馈）相比，我们观察到自觉用力程度降低，身体活动的愉悦感增强。我们还观察到受试者的注意力焦点发生了转变，从（无VR反馈时的）关联状态转变为（VR反馈条件下的）分离状态。此外，VR环境中虚拟教练的存在引发了对（虚拟）位移速度的系统性调节，其与自觉愉悦感和用力程度的关系尚需进一步研究。
