The interindividual variability in the efficacy of regular endurance exercise to lower blood pressure is high. Therefore, to optimize training prescriptions, predictors would be desirable. The main hypothesis of the present study was an association between postexercise hypotension after an exhaustive exercise test and chronic blood pressure reductions in response to an endurance training program.
Uncontrolled prospective training study.
University department.
Healthy untrained subjects were recruited by flyers. Inclusion criteria were age 30 to 60 years, body mass index 25 to 35 kg/m(2), untrained status (<1 hour/week regular activity; V[Combining Dot Above]O(2max) < 45 mL·min(-1)·kg(-1)), blood pressure 150/95 mm Hg, nonsmoker; 14 subjects were included, 12 could be analyzed.
Walking/running 4 times per week at 60% heart rate reserve for 4 weeks.
Difference in blood pressure from the initial resting value to 1 and 24 hours after the initial test (acute) and the resting value before the final test (chronic), respectively.
Initial resting systolic blood pressure was 134 ± 18 mm Hg. Values were significantly reduced at all time points thereafter (1 hour: 125 ± 13 mm Hg; 24 hours: 128 ± 12 mm Hg; final: 125 ± 18 mm Hg). Acute and chronic changes correlated significantly (1 hour: P = 0.003; r = 0.77; 24 hours: P = 0.017; r = 0.67). Results for diastolic blood pressure were comparable yet less pronounced.
The magnitude of postexercise hypotension is a promising candidate for the prediction of individual blood pressure-related training efficacy. Easily determined, it might be used to improve training prescriptions. However, further studies are needed to assess predictive accuracy.
常规耐力运动降低血压的个体间疗效差异很大。因此，为了优化训练方案，需要有预测指标。本研究的主要假设是，在一项耗竭性运动试验后出现的运动后低血压与对耐力训练计划的慢性血压降低之间存在关联。
未对照的前瞻性训练研究。
大学系。
通过广告招募健康的未训练受试者。纳入标准为年龄 30 至 60 岁，体重指数 25 至 35kg/m(2)，未训练状态（每周定期活动<1 小时；V[Combining Dot Above]O(2max)<45mL·min(-1)·kg(-1)），血压 150/95mmHg，不吸烟；共纳入 14 名受试者，其中 12 名可进行分析。
每周 4 次，以 60%心率储备行走/跑步，持续 4 周。
分别与初始静息值相比，初始试验后 1 小时和 24 小时（急性）和最后一次试验前的静息值（慢性）之间的血压差异。
初始静息收缩压为 134±18mmHg。此后所有时间点的血压均显著降低（1 小时：125±13mmHg；24 小时：128±12mmHg；最后：125±18mmHg）。急性和慢性变化显著相关（1 小时：P=0.003；r=0.77；24 小时：P=0.017；r=0.67）。舒张压的结果相似，但程度较轻。
运动后低血压的幅度是预测个体血压相关训练效果的一个有前途的候选指标。它易于确定，可能用于改善训练方案。然而，需要进一步的研究来评估预测的准确性。
