The purpose of this study was to examine the antihypertensive effects of lower extremity aerobic exercise on resting systolic and diastolic blood pressure among hypertensive adults. Nine studies representing a total of 245 subjects (147 exercise, 98 control) met the criteria for inclusion. Using the meta-analytic technique, exercise-induce effect size reductions significantly different from zero were found for both resting systolic and diastolic blood pressure (mean +/- SD, systolic: 0.63 +/- 0.66, 95% confidence interval, 0.12 to 1.14; diastolic: 0.35 +/- 0.19, 95% confidence interval, 0.19 to 0.49). Effect sizes corresponded with decreases of approximately 7 +/- 5 and 6 +/- 2 mm Hg for resting systolic and diastolic blood pressure, respectively. None of the changes were significant for the control groups. The results of this study suggest that lower extremity aerobic exercise has an antihypertensive effect on resting systolic and diastolic blood pressure in adults. However, a need exists for more meticulously controlled investigations on this topic.
本研究的目的是检验下肢有氧运动对高血压成年人静息收缩压和舒张压的降压效果。九项研究共纳入245名受试者（147名运动组，98名对照组），符合纳入标准。采用荟萃分析技术，发现运动诱导的效应量降低在静息收缩压和舒张压方面均显著不同于零（均值±标准差，收缩压：0.63±0.66，95%置信区间，0.12至1.14；舒张压：0.35±0.19，95%置信区间，0.19至0.49）。效应量分别对应静息收缩压和舒张压降低约7±5和6±2毫米汞柱。对照组的所有变化均无显著性。本研究结果表明，下肢有氧运动对成年人静息收缩压和舒张压有降压作用。然而，对于该主题需要进行更严格控制的研究。
