简要总结
The goal of this clinical trial is to explore the effects of virtual reality use on maximal aerobic exercise test performance (aerobic capacity) in healthy adults. The main questions it aims to answer are:
- Does using a virtual reality program during a maximal aerobic exercise test lead to differences in VO2peak (maximal aerobic capacity)? and,
- Does using a virtual reality program during a maximal aerobic exercise test lead to differences in work rate at the ventilatory threshold?
Participants will complete a maximal aerobic exercise test two times (separated by 1 week of recovery) under the following conditions:
- normal testing conditions in a lab
- while viewing a virtual reality video
Researchers will compare the test results of both conditions to see if the use of a virtual reality program alters VO2peak or the ventilatory threshold.
详细描述
Virtual reality imparts a dissociative effect on users during exercise, such that the physical activity task is experienced as more enjoyable and pleasant, requires less exertion, and requires less physiological function for a given submaximal work rate.
This array of positive effects may be particularly advantageous during a maximal aerobic exercise test, mainly because participant motivation and negative psychological state often lead to premature test termination. Ameliorating the unpleasantness of this type of exercise test with the use of virtual reality technology may prolong effort expenditure during the test and result in superior performance compared to a control condition.
Additionally, improving physiological function at submaximal work rates may lead to alterations in other important testing outcomes, particularly the ventilatory threshold. The ventilatory threshold is used as a reference point for prescribing exercise intensity. An intervention that modifies this value would have repercussions for physical fitness practitioners who prescribe exercise intensity relative to the ventilatory threshold.
The general purpose of this study is to determine the effect of virtual reality on maximal aerobic exercise test performance in healthy adults. The specific questions it aims to answer are:
- Does using a virtual reality program during a maximal aerobic exercise test lead to differences in VO2peak (maximal aerobic capacity)? and,
- Does using a virtual reality program during a maximal aerobic exercise test lead to differences in work rate at the ventilatory threshold?

盲法说明
It is not possible to mask the participant or data collection personnel from the conditions because the Virtual Reality condition requires that the headset be worn. Metabolic data and resulting outcomes (i.e. VO2peak value) will be analyzed by independent research assistants who will be blinded to the condition under which the data were gathered.
