摘要

背景：目前尚不清楚等长握力（IHG）运动是否会影响高血压和血压正常者的血压。目的：比较不同静息血压组运动后低血压的变化。方法：56名马来男性志愿者（12名血压正常，14名高血压前期，19名高血压1期和11名高血压2期）以最大握力收缩的30%完成了四组2分钟的等长握力练习，两组之间休息一分钟。在IHG运动前后测量收缩压（SBP）、舒张压（DBP）、脉压（PP）、平均动脉压（MAP）、静息心率（RHR）和握力（HGS）。使用配对样本t检验、单因素方差分析和双向重复测量ANCOVA来检验数据。结果：除RHR和HGS外，所有参数在运动后BP组均发生了显著变化。与其他组相比，高血压1期患者的收缩压、MAP和HGS显著降低（收缩压=-6.3±0.6 mmHg；MAP=-4.8±1.1 mmHg；HGS=-6.8±-0.4 mmHg）。同时，在高血压2期中，DBP降低最多（平均值=-5.2±0.6mmHg）。结论：目前的研究发现，高血压1期和2期患者在进行IHG运动后，血压显著降低。

The effect of a single session of isometric handgrip exercise on blood pressure

BACKGROUND: It is unknown whether a session of isometric handgrip (IHG) exercise can influence the blood pressure of hypertensive and normotensive individuals. OBJECTIVE: To compare post exercise hypotension among groups with different resting blood pressure (BP) levels. METHODS: 56 Malay male volunteers (12 normotensive, 14 pre-hypertensive, 19 hypertensive stage 1, and 11 hypertensive stage 2) completed four sets of 2-minute isometric handgrip exercises at 30% of their maximum handgrip contraction with a one-minute break between the sets. Systolic BP (SBP), diastolic BP (DBP), pulse pressure (PP), mean arterial pressure (MAP), resting heart rate (RHR), and handgrip strength (HGS) were measured before and after an hour of IHG exercise. A paired sample t-test, one-way ANOVA, and two-way repeated measure ANCOVA were used to examine the data. RESULTS: All parameters, except RHR and HGS, were significantly changed following the exercise across the BP groups. The SBP, MAP, and HGS were greatly reduced among hypertensive stage 1 (SBP =-6.3 ± 0.6 mmHg; MAP =-4.8 ± 1.1 mmHg; HGS =-6.8 ±-0.4 mmHg) compared to other groups. Meanwhile, the most DBP was reduced among hypertensive stage 2 (mean =-5.2 ± 0.6 mmHg). CONCLUSIONS: The current study discovered a significant reduction in BP among hypertensive stage 1 and 2 individuals after a session of IHG exercise.

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
