Physical and Physiological Characterization of Custom-Made Virtual Reality Exergames: A Pilot Study

Area of Science:

• Gerontology
• Human-Computer Interaction
• Exercise Science

Background:

• Aging population requires innovative physical activity solutions.
• Virtual reality (VR) offers a novel approach for health interventions.
• Older adults often face barriers to traditional exercise programs.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of FitFest, a custom VR system, for delivering physical activity (PA) sessions to older adults.
• To assess the impact of VR exergames on PA intensity, heart rate, and user experience.
• To identify factors influencing the adoption and continued use of VR-based interventions in older populations.

Main Methods:

• A pilot study involving seven older adults (mean age 67.0 years) tested two VR exergames (Wine Fest, Flower Fest).
• Measurements included physical activity intensity, heart rate (HR), rate of perceived exertion (RPE), and system usability.
• User feedback on system friendliness and interest in continued use was collected.

Main Results:

• VR sessions comprised 56.5% sedentary behavior and 42.1% light PA, averaging 436.7 steps and 92.1 bpm.
• Wine Fest showed trends towards reduced sedentary time and increased light PA compared to Flower Fest.
• Participants rated tasks requiring cardiovascular and strength efforts as more demanding.

Conclusions:

• FitFest demonstrates potential for promoting light physical activity in older adults.
• System usability and technical support are crucial for successful VR intervention adoption.
• Further research is needed to optimize VR exergames for sustained engagement and health benefits in seniors.
