Abstract

BACKGROUND

Virtual reality (VR) has been suggested to be effective at enhancing physical exercises because of its immersive characteristics. However, few studies have quantitatively assessed the range of motion and brain activity during VR exercises.

OBJECTIVE

We hypothesized that 3D immersive VR could stimulate body movement and brain activity more effectively than standard exercises and that the increased range of motions during 3D immersive VR exercises would be associated with orbitofrontal activation.

METHODS

A randomized crossover trial was conducted to compare exercises with and without VR. A total of 24 healthy males performed the same motions when exercising with and without 3D immersive VR, and the recorded videos were used for motion analysis. Hemodynamic changes in the prefrontal cortex were assessed using functional near-infrared spectroscopy.

RESULTS

There were significant differences in the total angle (z=-2.31; P=.02), length (z=-2.78; P=.005), calorie consumption (z=-3.04; P=.002), and change in accumulated oxygenated hemoglobin within the right orbitofrontal cortex (F=9.36; P=.003) between the VR and offline trials. Hemodynamic changes in the right orbitofrontal cortex were positively correlated with the total angle (r=0.45; P=.001) and length (r=0.38; P=.007) in the VR exercise; however, there was no significant correlation in the offline trial.

CONCLUSIONS

The results of this study suggest that 3D immersive VR exercise effectively increases the range of motion in healthy individuals in relation to orbitofrontal activation.

摘要

背景

虚拟现实（VR）因其沉浸式特性被认为在增强体育锻炼方面有效。然而，很少有研究定量评估VR锻炼期间的运动范围和大脑活动。

目的

我们假设3D沉浸式VR比标准锻炼能更有效地刺激身体运动和大脑活动，并且3D沉浸式VR锻炼期间运动范围的增加将与眶额激活相关。

方法

进行了一项随机交叉试验，以比较有和没有VR的锻炼。总共24名健康男性在有和没有3D沉浸式VR锻炼时进行相同动作，记录的视频用于运动分析。使用功能近红外光谱评估前额叶皮质的血流动力学变化。

结果

VR试验和离线试验之间在总角度（z=-2.31；P=0.02）、长度（z=-2.78；P=0.005）、卡路里消耗（z=-3.04；P=0.002）以及右侧眶额皮质内累积氧化血红蛋白的变化（F=9.36；P=0.003）方面存在显著差异。在VR锻炼中，右侧眶额皮质的血流动力学变化与总角度（r=0.45；P=0.001）和长度（r=0.38；P=0.007）呈正相关；然而，在离线试验中没有显著相关性。
