目的：观察单次不同强度和时间的步行训练对中老年男性24h内收缩压的效应。
方法：实验选取40例血压正常或者轻中度高血压的中老年男性受试者，所有受试者均在研究开始时进行1d的血压监测，记录受试者日常生活状态下的血压以进行空白对照（空白对照组）。受试者在进行心肺运动试验检测其峰值摄氧量VO2peak之后，采用自身对照法，分别进行运动量为30min 45% VO2peak（3045组）、30min 65%VO2peak（3065组）、60min 45%VO2peak（6045组）的单次步行训练，每两次步行训练之间间隔3—5d。每次干预后，分别记录每组受试者在运动前、运动结束时、运动结束后1h、4h、12h和24h的收缩压。
结果：与运动前相比，3045组患者收缩压在运动后、运动结束后1h均明显下降（P＜0.05），在运动结束后4h降低程度最显著（P＜0.01），在运动结束后12h时仍有降低，但差异已无显著性（P＞0.05）；3065组和6045组患者收缩压在运动后1h时显著下降（P＜0.05），在运动后4h时仍有降低，但差异无显著性意义（P＞0.05）。空白对照组患者24h内血压波动无明显变化，所有干预组在运动后24h时收缩压均回到原有水平。
结论：相对于30min 65%VO2peak、60min 45%VO2peak的运动量来说，30min 45%VO2peak的单次步行训练降压时效更长，接近12h。因此，对于血压正常或轻中度高血压的中老年男性来说，一天两次30min 45%VO2peak的步行训练能够有效维持急性运动的降压效应。 |

| Abstract
Objective: To observe the effect of single walking exercise with different intensity and duration on systolic blood pressure(SBP) in aging males.
Method: Forty aging males subjects with normotensive or mild-moderate hypertension were selected. All subjects received blood pressure monitor for 1d, their blood pressure were recorded and used as daily living blank control. In cardiopulmonary exercise test subject's VO2peak was measured a week before exercise. Subjects of every group did single walking exercise in 30 min 45%VO2peak (3045 group), 30 min 65%VO2peak (3065 group), 60 min 45%VO2peak (6045 group) respectively and every twice exercises were separated by 3—5d. After every walking exercise intermention, SBP were tested pre-walk, post walk, 1h, 4h, 12h and 24h post walk.
Result: SBP of subjects in 3045 group decreased significantly after walking and at 1h post walk (P＜0.05), and reduced more at 4h post walk (P＜0.01). SBP still reduced at 12h post walk but the difference was not significant(P>0.05). SBP was only significantly lowered at 1h post walk in 3065 and 6045 groups(P＜0.05). SBP still reduced at 4h post walk but the difference was not significant(P>0.05). In control group SBP did not change significantly over 24h post walk and in all intervention groups SBP returned to the previous level at 24h post walk.
Conclusion: Walking for 30min at 45％VO2peak is an effective therapy for reducing SBP nearly 12h in elderly men compared to other two groups. Furthermore, this type of activity appears to be more effective than walking with higher intensity or longer duration. Therefore, performing 30min 45%VO2peak of brisk walking twice a day can effectively keep the reducing blood pressure effect of acute exercise. |
