Moderate isometric handgrip exercise is an effective tool in the management of systemic hypertension.
To evaluate the effectiveness of a high intensity isometric handgrip exercise protocol for the reduction of blood pressure in older people with pre or stage-1 hypertension.
Twenty-three participants aged 73.8 ± 6.6 years (range 61-90) completed eight weeks of high intensity isometric handgrip training 2 times per week, performing 32 contractions maintained for 5 seconds, with breaks of 5 seconds. Blood pressure (BP) was measured at baseline and at the end of the intervention.
Systolic blood pressure decreased from 141 ± 11 to 127 ± 10 mmHg (p < 0.01). The decrease in diastolic blood pressure was from 79 ± 7 to 74 ± 6 mmHg (p < 0.01).
A blood pressure reduction was recorded in these participants after a period of high intensity isometric handgrip exercise.
中等强度等长握力运动是治疗系统性高血压的有效手段。
评估高强度等长握力运动方案对降低老年前期或1期高血压患者血压的有效性。
23名年龄在73.8±6.6岁（范围61 - 90岁）的参与者，每周进行2次、为期8周的高强度等长握力训练，每次进行32次持续5秒的收缩，每次收缩间隔5秒。在基线和干预结束时测量血压（BP）。
收缩压从141±11 mmHg降至127±10 mmHg（p < 0.01）。舒张压从79±7 mmHg降至74±6 mmHg（p < 0.01）。
经过一段时间的高强度等长握力运动后，这些参与者的血压有所下降。
