Dynamic physical exercise (walking, swimming, and so on) is an important component of lifestyle changes to reduce blood pressure; however, many individuals are unwilling or unable to adopt this lifestyle change. Isometric exercise has not traditionally been recommended as an alternative to dynamic exercise and has not been well studied. A meta-analysis of controlled trials of isometric exercise on resting blood pressure was therefore undertaken. Five trials were identified including a total of 122 subjects. Isometric exercise for <1 h per week reduced systolic blood pressure by 10.4 mm Hg and diastolic blood pressure by 6.7 mm Hg. These changes are similar to those achieved with a single pharmacological agent. These results suggest that isometric exercise may be of value as part of lifestyle advice in maintaining a desirable blood pressure.
动态体育锻炼（如散步、游泳等）是降低血压的生活方式改变的重要组成部分；然而，许多人不愿意或无法采取这种生活方式的改变。等长运动传统上不被推荐作为动态运动的替代，而且也没有得到很好的研究。因此，对等长运动对静息血压的对照试验进行了荟萃分析。确定了五项试验，共包括 122 名受试者。每周进行不到 1 小时的等长运动可使收缩压降低 10.4mmHg，舒张压降低 6.7mmHg。这些变化与单一药物治疗的效果相似。这些结果表明，等长运动可能作为维持理想血压的生活方式建议的一部分具有价值。
