To evaluate the effects of 20 weeks of home-based isometric handgrip training (IHT) compared with usual care on systolic blood pressure (SBP) in adults.
This was a randomised, controlled, assessor-blinded trial. Participants were randomised to either IHT (intervention group) or usual care (control group).
Participants randomised to the intervention group performed a session of 16 min of effective workout home-based IHT three times per week for 20 weeks. Participants randomised to the control group were asked to continue their daily activities as usual.
The primary outcome was the difference in SBP between groups over 20 weeks. Secondary outcomes were diastolic blood pressure, heart rate, handgrip strength, and self-administered home blood pressure measures.
Forty-eight adults (mean [SD] age, 64 [8] years) were included in this trial. The adjusted between-group mean difference in SBP was 8.12 mmHg (95% CI 0.24 to 16.01, = 0.04) - favouring the usual care group. No differences between groups were found in any of the home blood pressure measurements.
This trial showed that 20 weeks of home-based isometric handgrip training was not superior compared to the usual care in lowering SBP.
评估与常规护理相比，为期20周的居家等长握力训练（IHT）对成年人收缩压（SBP）的影响。
这是一项随机、对照、评估者盲法试验。参与者被随机分为IHT组（干预组）或常规护理组（对照组）。
随机分配到干预组的参与者每周进行3次、每次16分钟的有效居家IHT锻炼，持续20周。随机分配到对照组的参与者被要求照常继续他们的日常活动。
主要结局是20周内两组间SBP的差异。次要结局包括舒张压、心率、握力以及自我测量的家庭血压。
48名成年人（平均[标准差]年龄，64[8]岁）纳入本试验。调整后的组间SBP平均差异为8.12 mmHg（95%CI 0.24至16.01，P = 0.04），有利于常规护理组。在任何家庭血压测量中，两组之间均未发现差异。
本试验表明，为期20周的居家等长握力训练在降低SBP方面并不优于常规护理。
