OBJECTIVES
Greater arterial stiffness and poor 24h blood pressure (BP) are recognized as indicators of poor cardiovascular health. Evidence has shown that high intensity interval training (HIIT) may be a superior alternative to moderate intensity continuous training (MICT) for improving cardiovascular disease risk factors such as cardiorespiratory fitness and vascular function. However, there are limited data comparing the effect of HIIT to MICT on central arterial stiffness and/or 24h BP response. The purpose of this study was to compare HIIT versus MICT on central arterial stiffness and 24h BP outcomes by systematic review and meta-analysis.
DESIGN
A systematic review and meta-analysis was conducted.
METHODS
Eligible studies were exercise training interventions (≥4weeks) that included both HIIT and MICT and reported central arterial stiffness, as measured by pulse wave velocity and augmentation index and/or 24h BP outcome measures.
RESULTS
HIIT was found to be superior to MICT for reducing night-time diastolic BP (ES: -0.456, 95% CI: -0.826 to -0.086mmHg; P=0.016). A near-significant greater reduction in daytime systolic (ES: -0.349, 95% CI: -0.740 to 0.041mmHg; p=0.079) and diastolic BP was observed with HIIT compared to MICT (ES: -0.349, 95% CI: -0.717 to 0.020mmHg; p=0.063). No significant difference was found for other BP responses or arterial stiffness outcomes.
CONCLUSIONS
HIIT leads to a superior reduction in night-time diastolic BP compared to MICT. Furthermore, a near-significant greater reduction in daytime BP was found with HIIT compared to MICT. No significant difference was observed for changes to central arterial stiffness between HIIT and MICT.
目的
动脉僵硬度增加和 24 小时血压（BP）控制不佳被认为是心血管健康不良的指标。有证据表明，高强度间歇训练（HIIT）可能优于中等强度持续训练（MICT），可改善心肺健康等心血管疾病危险因素以及血管功能。然而，比较 HIIT 与 MICT 对中心动脉僵硬度和/或 24 小时 BP 反应的影响的数据有限。本研究旨在通过系统评价和荟萃分析比较 HIIT 与 MICT 对中心动脉僵硬度和 24 小时 BP 结果的影响。
设计
系统评价和荟萃分析。
方法
纳入的研究为运动训练干预（≥4 周），包括 HIIT 和 MICT，并报告中心动脉僵硬度，通过脉搏波速度和增强指数以及/或 24 小时 BP 结果来测量。
结果
HIIT 可降低夜间舒张压（ES：-0.456，95%CI：-0.826 至-0.086mmHg；P=0.016），优于 MICT。与 MICT 相比，HIIT 可显著降低日间收缩压（ES：-0.349，95%CI：-0.740 至 0.041mmHg；p=0.079）和舒张压（ES：-0.349，95%CI：-0.717 至 0.020mmHg；p=0.063），但差异无统计学意义。其他 BP 反应或动脉僵硬度结果无显著差异。
结论
与 MICT 相比，HIIT 可显著降低夜间舒张压。此外，与 MICT 相比，HIIT 可使日间 BP 显著降低。HIIT 和 MICT 对中心动脉僵硬度的改变无显著差异。
