摘要

研究高强度收缩和低强度收缩(有或无血流限制)对血压和血液动力学参数变化的影响。共有 179 名参与者(18-35 岁)被随机分配到每周锻炼 3 次、为期 6 周的三个训练组或不锻炼对照组中。各组情况如下1)对照组[CON,n = 44];2)完成 4 组两分钟等长收缩,最大自主收缩率为 30%[LI,n = 47];3)完成 4 组两分钟等长收缩,最大自主收缩率为 30%,同时将 12 厘米袖带充气至动脉闭塞压的 50%[LI+BFR,n = 41];或 4)完成 4 组持续 5 秒的最大等长收缩[MAX,n = 47]。测量前后的血压、血管阻力和反应性充血。数据以平均值(标清)表示。没有证据表明 SBP(BF10:0.066)、DBP(BF10:0.057)、血管阻力(BF10:0.085)或反应性充血峰值发生了变化(BF10:0.044)或 A.U.C.(BF10:0.074)。CON、LI、LI+BFR 和 MAX 的 SBP 变化分数分别为 1.1 (6.7)、0.7 (5.8)、-0.4 (6.5) 和 -0.9 (6.3) mmHg。CON、LI、LI+BFR 和 MAX 的 DBP 变化分数分别为 1.5 (6.6)、1.5 (7)、-0.7 (5.9) 和 0.3 (6.3) mmHg。尽管被推荐为控制血压的非药物方法,但进行或不进行 BFR 的等长运动并不能降低血压。未来的工作可以研究在低强度方案之前加入日常力量测试。

The Effect of Isometric Handgrip Training With and Without Blood Flow Restriction on Changes in Resting Blood Pressure.

To investigate the effects of high-intensity contractions and low-intensity contractions with and without blood flow restriction on changes in blood pressure and hemodynamic parameters. A total of 179 participants (18-35 years) were randomly assigned to one of three training groups that exercised 3 times per week for six weeks or a non-exercise control group. The groups are as follows: 1) Control [CON, n = 44]; 2) completed 4 sets of two-minute isometric contractions at 30% maximal voluntary contraction [LI, n = 47]; 3) completed 4 sets of two-minute isometric contractions at 30% maximal voluntary contraction with a 12 cm cuff inflated to 50% of arterial occlusion pressure [LI+BFR, n = 41]; or 4) completed 4 maximal isometric contractions lasting 5 seconds [MAX, n = 47]. Blood pressure, vascular resistance, and reactive hyperemia were measured at pre and post. Data are presented as means (SD). There was no evidence that SBP (BF10: 0.066), DBP (BF10: 0.057), vascular resistance (BF10: 0.085), or peak reactive hyperemia changed (BF10: 0.044) or A.U.C. (BF10: 0.074). Change scores for SBP were 1.1 (6.7), 0.7 (5.8), -0.4 (6.5), and -0.9 (6.3) mmHg for CON, LI, LI+BFR, and MAX, respectively. DBP change scores were 1.5 (6.6), 1.5 (7), -0.7 (5.9), and 0.3 (6.3) mmHg for CON, LI, LI+BFR, and MAX, respectively. Although recommended as a non-pharmacological method of blood pressure control, isometric exercise with or without BFR did not lower blood pressure. Future work could examine the inclusion of a daily strength test prior to the low intensity protocol.
