目的探究急性有氧运动和抗阻训练对中心动脉压的影响.方法选取在实验干预前6个月均无系统有氧运动和抗阻训练史的健康男性受试者15例,采用自身配对实验设计,即所有受试者先进行1次30 min中等强度有氧训练,2周后,再以最大重复1次(1-RM)力量的60％强度进行1次8个动作抗阻训练.分别于急性有氧运动和抗阻训练的干预前(基础值)、干预后5,20和40 min(恢复期值),检测右上臂肱动脉血压及中心动脉压指标,并对2种干预前后不同恢复期的肱动脉血压、中心动脉收缩压(CSBP)及桡动脉增益指数(AI)等指标变化进行统计学分析比较.结果急性中等强度有氧运动和抗阻训练后,CSBP在干预后40 min恢复期值与训练前的基础值相比,均明显下降(P＜0.05),分别从(102.33 ± 10.03)和(107.92±12.08) mmHg降至(93.33 ±8.87)和(94.00±9.78) mmHg,但比较2种干预后恢复期之间的CSBP变化,差异无统计学意义(P＞0.05);但有氧训练后40 min恢复期间,收缩压(SBP)和脉压差(PP)明显低于抗阻训练后,其中SBP在有氧运动训练后20 min恢复期值明显低于急性抗阻训练后20 min恢复期值[(108.08 ± 9.72)mmHg比(119.31±6.68) mmHg,P＜0.05],PP在有氧运动训练后恢复期20 min和40 min的值[(47.58 ±8.17)和(48.58 ±7.15) mmHg]亦明显低于急性抗阻训练后的同时间恢复期值[(65.75 ±5.67)和(59.08±7.74) mmHg],差异均有统计学意义(P＜0.05).桡动脉增益指数(AI)在有氧运动训练后5 min的恢复期值明显低于急性抗阻训练后的同时间恢复期值[(48.50±8.94)％比(59.69±14.13)％,P＜0.05].结论急性中等强度有氧运动和抗阻训练对中心动脉压均产生良性影响,而有氧运动可能对血压影响有着更为积极的作用.

Objective To explore the effects of aerobic exercise and resistance training on center arterial blood pressure.Methods Fifteen healthy men who had not practiced aerobic exercise or resistance training within the previous 6 months were enrolled in this study.A self-matched pairs design was adopted.All of the subjects performed moderate intensity aerobic exercise,for 30 min initially,and after 2 weeks,performed resistance training at 60％ of their l-repeat maximum effort (1-RM).Their central aortic systolic blood pressure (CSBP) before and after aerobic exercise and resistance training were measured and compared,respectively.The changes in CSBP and an augmentation index (AI) of radial artery and relative blood pressure were compared between the two interventions.Results CSBP decreased significantly after both sorts of training.The two types of training showed no significant difference in their effects on CSBP.However,after a 20 min recovery,systolic blood pressure and pulse pressure were significantly lower after aerobic exercise than after resistance training.The significant difference persisted after 20 min and 40 min of re-covery.The AI of the radial artery was also significantly lower 5 min after aerobic exercise than after resistance train-ing.Conclusions After moderate aerobic exercise and resistance training,CBSP,AI and systolic pressure all display favorable changes.However,moderate intensity aerobic exercise provides the better effect in improving blood pressure.
