本研究的目的是调查参与者在目标心率区（THRZ）运动的时间是否会影响心脏事件发生1年后血压（BP）的变化。使用便携式心率监测器客观地测量生活方式运动（习惯性的、小的运动机会）和强度。采用线性混合模型分析331名参与者的血压变化。基线时的平均血压为118/70 mmHg， 1年内收缩压和舒张压分别升高4.79 mmHg （p < 0.001）和2.09 mmHg （p = 0.002）。总体而言，参与者的生活方式锻炼水平有所下降。在控制时间、年龄、性别和研究组后，收缩压变化与THRZ时间呈负相关。考虑到推荐运动的次优参与，生活方式运动影响THRZ降低血压时间的潜在机制值得在该人群中进一步研究。
The purpose of this study was to investigate whether the amount of time participants exercised in the target heart rate zone (THRZ) influenced change in blood pressure (BP) 1 year following a cardiac event. Lifestyle exercise (habitual, small exercise opportunities) and intensity were objectively measured using portable heart rate monitors. Linear mixed models were used to analyze change in BP among 331 participants. Mean BP at baseline was 118/70 mmHg, and both systolic and diastolic BP increased from baseline to 1 year, 4.79 mmHg (p <.001) and 2.09 mmHg (p =.002), respectively. Overall, participants had a decrease in levels of lifestyle exercise. After controlling for time, age, gender, and study group, SBP change was inversely associated with amount of time in THRZ. Given suboptimal engagement in recommended exercise, the underlying mechanisms of lifestyle exercise effects on the time spent in THRZ to reduce BP warrants further study in this population.
