Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 to 65 with a diagnosis of prediabetes based on specific glucose level criteria.
✕Probably not a fit
Patients with diabetes or significant chronic diseases, as well as those with certain medical conditions affecting heart rate, will not benefit from this study.

What this trial studies
This study investigates the effects of heart rate variability biofeedback training combined with resonance frequency breathing on glucose metabolism in individuals diagnosed with prediabetes. The intervention aims to enhance autonomic nervous system function, which is believed to play a crucial role in insulin sensitivity and secretion. Participants will undergo a screening process to confirm their prediabetes status and will be trained in specific breathing techniques to potentially improve their metabolic health. The study seeks to provide a novel therapeutic approach for managing prediabetes.
Why it matters
Potential benefit: If successful, this intervention could help improve glucose metabolism and reduce the risk of developing type 2 diabetes in individuals with prediabetes.
How similar studies have gone: While the specific combination of techniques used in this study may be novel, previous studies have shown promising results in improving metabolic health through autonomic nervous system modulation.
