Background : The acute effects of high-intensity interval training (HIIT) on blood pressure (BP) may depend on the exercise protocol performed. Purpose: To compare the acute effect of high and low-volume HIIT on post-exercise and ambulatory BP in untrained older females diagnosed with both type 2 diabetes (T2D) and hypertension (HTN). Methods: Fifteen females (69 [65 ─ 74] years) completed a crossover study with three experimental conditions: 1) REST (35 min in sitting position); 2) HIIT10 (10 × 1 min at 90% heart rate max [HRmax]), and 3) HIIT4 (4 × 4 min at 90% HRmax). After each experimental condition, BP was measured under controlled (4 hours) and in subsequent free-living conditions (20 hours). Results: In the controlled post-condition 4-hour period, no significant interaction (time × condition) was observed for all BP parameters (p ≥ 0.082). Similarly, during the subsequent 20-hour free-living ambulatory monitoring (diurnal and nocturnal), no differences between conditions were detected (p ≥ 0.094). A significant reduction in nighttime pulse pressure was observed in both HIIT4 and HIIT10 compared to REST (46 [44 ─ 50], 45 [42 ─ 53] vs. 50 [45 ─ 57] mmHg, respectively; p ≤ 0.018) with no differences between HIIT conditions (p = 0.316). Changes in nocturnal systolic BP approached but did not reach statistical significance (p = 0.068). Conclusions: This study suggests that in untrained older females living with T2D and HTN, the HIIT10 and HIIT4 protocols have very limited to no acute effect on post-exercise and ambulatory BP. The fact that the vast majority of participants had well-controlled office and ambulatory BP values as well as low cardiorespiratory fitness could explain these findings.

高强度间歇运动对 2 型糖尿病和高血压女性血压的急性影响。



背景 : 高强度间歇训练 (HIIT) 对血压 (BP) 的急性影响可能取决于所执行的运动方案。目的:比较高容量和低容量 HIIT 对诊断为 2 型糖尿病 (T2D) 和高血压 (HTN) 的未经训练的老年女性运动后和动态血压的急性影响。方法:15 名女性 (69 [65 ─ 74] 岁) 完成了一项交叉研究,具有三个实验条件:1) REST(坐姿 35 分钟);2) HIIT10(10 × 1 分钟,最大心率为 90% [HRmax]),和 3) HIIT4(4 × 4 分钟,最大心率为 90%)。在每个实验条件之后,在受控 (4 小时) 和随后的自由生活条件下 (20 小时) 测量血压。结果:在受控的后条件 4 小时内,所有 BP 参数均未观察到显着交互 (时间×条件) (p ≥ 0.082)。同样,在随后的 20 小时自由生活动态监测 (昼夜和夜间) 中,未检测到条件之间的差异 (p ≥ 0.094)。与 REST 相比,HIIT4 和 HIIT10 均观察到夜间脉压显著降低 (分别为 46 [44 ─ 50]、45 [42 ─ 53] 与 50 [45 ─ 57] mmHg;p ≤ 0.018),HIIT 条件之间没有差异 (p = 0.316)。夜间收缩压的变化接近但未达到统计学意义 (p = 0.068)。结论: 这项研究表明,在患有 T2D 和 HTN 的未经训练的老年女性中,HIIT10 和 HIIT4 方案对运动后和动态血压的急性影响非常有限或没有急性影响。绝大多数参与者的办公室和动态血压值控制良好以及心肺健康低的事实可以解释这些发现。
