Exercise training may reduce blood pressure.
To determine the effects of a high intensity interval training (HIIT) exercise protocol on systolic and diastolic blood pressure in hypertensive subjects.
Eleven men and 27 women aged 46.4 ± 9.8 years were divided in two groups according to their blood pressure. Sixteen were classified as normotensive and 22 as hypertensive. All attended an exercise program with 3 sessions per week for a total of 24 sessions. Each session consisted of one minute of intense exercise performed on a stationary bike, followed by an inactive pause lasting two minutes. This cycle was repeated 10 times and it was thus called 1 * 2 * 10. Blood pressure, weight (kg) and body fat were assessed.
In the hypertensive group, there was a significant reduction in systolic blood pressure from 145.4 ± 9.0 to 118.3 ± 15.6 mm Hg (p < 0.05). No significant change was observed in diastolic blood pressure (84.9 ± 3.9 and 85.8 ± 17.6 mmHg. Thus, there was a mean reduction in systolic pressure of 27. 7 ± 18.9 mmHg. Therefore, 73% of patients achieved systolic pressures within normal range, without medication.
The 1 * 2 * 10 exercise method is effective to improve and restore normal blood pressure in persons with hypertension in a period of two months and 24 sessions.
运动训练可能降低血压。
确定高强度间歇训练（HIIT）运动方案对高血压患者收缩压和舒张压的影响。
46.4±9.8岁的11名男性和27名女性根据血压分为两组。16人被归类为血压正常，22人为高血压患者。所有人都参加了一个运动项目，每周3次，共24次。每次训练包括在固定自行车上进行1分钟的剧烈运动，然后是持续2分钟的无运动间歇。这个循环重复10次，因此称为1210。评估血压、体重（kg）和体脂。
在高血压组中，收缩压从145.4±9.0显著降低至118.3±15.6 mmHg（p<0.05）。舒张压未见显著变化（84.9±3.9和85.8±17.6 mmHg）。因此，收缩压平均降低27.7±18.9 mmHg。因此，73%的患者在未用药的情况下收缩压达到正常范围。
1210运动方法在两个月内进行24次训练，对改善和恢复高血压患者的正常血压有效。
