Key result
Endurance training in healthy seniors improved RRI variability with increasing doses over 1 year, while moderate doses for 3-6 months optimally improved baroreflex sensitivity.

Does progressive endurance training improve autonomic circulatory control in healthy sedentary seniors compared to young individuals and Masters athletes?
Progressive endurance training in healthy seniors improves cardiac autonomic function, with RRI variability reaching levels of healthy young individuals after 12 months, though baroreflex gain peaks earlier and remains below young levels.
Okazaki et al. (2005) conducted an observational in Healthy aging (n=33). Endurance training vs. Masters athletes and healthy sedentary young individuals was evaluated on R-wave-R-wave interval (RRI), beat-to-beat blood pressure (BP) variability, and transfer function gain. Endurance training in healthy seniors improved RRI variability with increasing doses over 1 year, while moderate doses for 3-6 months optimally improved baroreflex sensitivity.
