The beneficial impact of regular exercise on cardiovascular health is partly mediated by psychobiological mechanisms. However, the effect of acute exercise on psychobiological responses is unclear. Thus, we performed a systematic review of randomised controlled trials (RCTs) that examined the effect of acute aerobic exercise on blood pressure (BP) responses (the change from baseline to stress) to psychosocial laboratory tasks. Fifteen RCTs met inclusion criteria of which ten demonstrated significant reductions in post-exercise stress related BP responses compared with control (mean effect sizes for systolic and diastolic BP, 0.38 and 0.40). Studies involving greater exercise doses tended to show larger effects, with the minimum dose to show a significant effect being 30 min at 50% VO2max. No other moderators emerged from the examination of participant characteristics, research designs and stressor characteristics. In conclusion, an acute bout of aerobic exercise appears to have a significant impact on the BP response to a psychosocial stressor.
规律运动对心血管健康的有益影响部分是由心理生物学机制介导的。然而，急性运动对心理生物学反应的影响尚不清楚。因此，我们对随机对照试验（RCT）进行了系统评价，这些试验研究了急性有氧运动对心理社会实验室任务的血压（BP）反应（从基线到应激的变化）的影响。15项RCT符合纳入标准，其中10项表明，与对照组相比，运动后与应激相关的血压反应显著降低（收缩压和舒张压的平均效应大小分别为0.38和0.40）。涉及更大运动剂量的研究往往显示出更大的效果，显示出显著效果的最小剂量是在50%最大摄氧量下运动30分钟。在对参与者特征、研究设计和应激源特征的研究中，没有出现其他调节因素。总之，一次急性有氧运动似乎对心理社会应激源的血压反应有显著影响。
