Key result
Moderate endurance training for 3 months decreased BP, HR, and vascular resistance, but more prolonged and intense training up to 12 months did not augment these changes further.
Why the study?

May support 3-month moderate regimens for hemodynamic gains in sedentary adults; leaves open whether prolonged intensity adds benefit in RCTs.

Does progressive endurance training improve cardiovascular hemodynamics and autonomic regulation in initially sedentary healthy adults?
Moderate endurance training for 3 months is sufficient to achieve beneficial cardiovascular adaptations, whereas more prolonged and intense training does not provide additional autonomic benefits.
Iwasaki et al. (2003) conducted an observational in Healthy, initially sedentary adults (n=11). Progressive endurance training vs. Baseline (control values) was evaluated on Regulation of heart rate (HR) and blood pressure (BP), steady-state hemodynamics, and dynamic cardiovascular regulation. Moderate endurance training for 3 months decreased BP, HR, and vascular resistance, but more prolonged and intense training up to 12 months did not augment these changes further.
