12-week Brisk Walking Improved Chronotropic Response in Hypertensive Patients

Int J Sports Med DOI: 10.1055/a-1978-5907We investigated the effects of 12-week brisk walking on chronotropic response in
hypertensive patients aged 40–69. 77 participants in exercise group
underwent 12-week brisk walking, while 66 participants in control group received
health education. Chronotropic parameters, resting blood pressure, and physical
fitness including peak oxygen consumption (VO2peak) were measured.
After 12 weeks, the systolic blood pressure (SBP) was decreased
(−6.104 mmHg, 95%CI −8.913 to
−3.295 mmHg, P<0.0001), while metabolic chronotropic
relationship (MCR) slope and VO2peak were increased (0.073,
95%CI 0.001 to 0.145, P=0.046;
1.756 mL/kg/min, 95%CI 0.891 to
2.622 mL/kg/min, P<0.0001) in exercise group
compared to baseline. The chronotropic response index (CRI) at
25–75 W load were decreased (−0.210, 95%CI
−0.307 to −0.112, P<0.0001; −0.144,
95%CI − 0.204 to −0.083, P<0.0001;
−0.078, 95%CI −0.135 to −0.022, P=0.007)
in control group after 12 weeks. The relative changes (%Δ) of
systolic and diastolic blood pressure were negatively correlated with
%ΔVO2peak (r=−0.233,
r=−0.187), while %ΔMCR and %ΔCRI
at 50–75 W load were positively correlated with
%ΔVO2peak after 12 weeks (...
