Key result
Low-intensity regular exercise training for 5 years did not prevent heart rate variability from decreasing or change blood pressure variability in older Finnish men.
Why the study?
Does regular physical activity improve heart rate variability and blood pressure variability in older men?

Low-intensity exercise does not preserve HRV or modify BPV in older men; challenges assumptions on autonomic benefits of mild long-term training.

Does regular physical activity improve heart rate variability and blood pressure variability in older men?
A 5-year low-intensity regular exercise training program did not prevent the age-related decrease in heart rate variability or alter blood pressure variability in older men.
Uusitalo et al. (2004) reported an RCT. Regular physical activity vs. Reference group was evaluated on Heart rate variability (HRV) and blood pressure variability (BPV). Low-intensity regular exercise training for 5 years did not prevent heart rate variability from decreasing or change blood pressure variability in older Finnish men.
