Key result
Habitual physical activity in T2D is linked to enhanced autonomic modulation and higher HRV.
Why the study?
Cardiac autonomic dysfunction is common in T2DM, but the relationship between HRV and habitual physical activity adjusted for metabolic and anthropometric factors remains underexplored.
Does habitual physical activity improve resting heart rate variability indices in adults with Type 2 Diabetes?
Cross-Sectional (n=41)
Does habitual physical activity improve resting heart rate variability indices in adults with Type 2 Diabetes?
p-value: p=0.021 for SDNN
Habitual physical activity is independently associated with enhanced autonomic modulation in adults with Type 2 Diabetes, supporting the use of HRV as a biomarker for guiding exercise interventions.

Supports exploring HRV as activity biomarker in T2D; leaves open causal effects on autonomic modulation.
Persiani et al. (2025) conducted a cross-sectional in Type 2 Diabetes (n=41). Habitual physical activity vs. Physical inactivity was evaluated on Heart rate variability (HRV) indices including SDNN, RMSSD, LF, and HF (p=0.021 for SDNN). Habitual physical activity in adults with type 2 diabetes was independently associated with enhanced autonomic modulation, including higher SDNN (p=0.021) and RMSSD (p=0.048).
