Responses in Posttherapy Recovery-Based Virtual Reality With Blood Flow Restriction in Older Women: A Randomized...

Area of Science:

• Exercise Physiology
• Rehabilitation Science
• Gerontology

Background:

• Blood flow restriction (BFR) and virtual reality-based therapy (VRT) are common interventions.
• The combined effects of VRT and BFR on older women's physiological and perceptual responses remain unstudied.

Purpose of the Study:

• To assess autonomic and hemodynamic changes after VRT with BFR (VRT-BFR) in older women.
• To evaluate perceptual responses during and after VRT-BFR exercise recovery.

Main Methods:

• A randomized crossover trial involving 17 older women.
• Interventions included VRT-BFR (40% occlusion), VRT alone, and a control group, with a 7-day washout period.
• Hemodynamic (heart rate, blood pressure, double product) and autonomic (RR intervals) parameters were monitored during and after exercise.

Main Results:

• In the VRT-BFR group, RR intervals decreased, while heart rate and double product increased during recovery.
• No significant differences were found between groups or in group-time interactions for the measured outcomes.
• The VRT-BFR intervention did not lead to autonomic, hemodynamic, or perceptual imbalance post-exercise.

Conclusions:

• Virtual reality-based therapy combined with blood flow restriction is safe for older women.
• This combined therapy does not induce autonomic, hemodynamic, or perceptual instability during post-exercise recovery.
