小编导读

为了保持健康,人们会通过习惯性运动(包括有氧运动和肌肉力量训练)来改善身体机能。众所周知,有氧运动训练可降低中枢收缩压。有趣的是,无氧运动训练(即高强度间歇训练)比中等强度的持续运动训练(一般的有氧运动训练)具有更有效的中枢降压效果。然而,如何结合无氧运动和肌肉力量训练改变中枢血压还不完全清楚。来自日本和韩国的多位学者在期刊Artery ResearcheISSN 1876-4401pISSN 1872-9312) 上合作发表了题为“Central Blood Pressure in Young Kendo Athletes: Implications of Combined Anaerobic and Strength Training”的文章,通过测量对比大学剑道运动员和没有运动习惯的同年龄段健康成年人的中枢血压,分析了无氧训练和力量训练相结合的重要意义。

要点介绍

研究背景:运动训练诱导的中枢性血压(BP)的适应依赖于运动方式。剑道是日本传统武术的一种,它的训练包含无氧和阻力训练,是一种独特的运动方式。然而,习惯性剑道训练对中枢血压的影响尚不明确。研究目的:比较无运动习惯的高水平剑道运动员与同龄对照组的中枢血压。研究方法:36名青年大学生剑道运动员(剑道运动员组)和29名青年习惯久坐者(对照组)参加了研究。通过广义传递函数从颈动脉波形估计中枢血流动力学,用Modelflow方法从肱动脉波形计算心搏量。研究结果:剑道运动员组的中心收缩压和中心脉压均高于对照组(p<0.01)。两组的中心舒张压无差异。心搏量指数;剑道运动员组的心搏量(按体表面积调整)和收缩期主动脉压最大上升率(dP/dTmax)显著高于对照组(p<0.05),反映左心室收缩力,且这些参数与cPP呈显著正相关(SVI:r=0.34p<0.01dP/dTmaxr=0.79p<0.01)。研究结论:习惯性剑道训练可通过提高左室收缩功能来提高中心脉压。注意以下几点:

1.    剑道结合了无氧训练和力量训练的特点,是研究训练适应性的理想方法;也就是说,与久坐对照组相比,剑道运动员拥有更高的无氧能力和肌肉力量。

2.    在本研究中,剑道运动员组的中心血压(中心收缩压和中心脉压)显著高于对照组。

3.    心搏量指数(SVI;剑道运动员组的心搏量(按体表面积调整)和收缩期最大主动脉压升高率(dP/dTmax)也显著高于对照组,但血压未增加。

4.    此外,SVIdP/dTmax与中心脉压呈显著正相关。

5.    这些结果表明,无氧运动和肌力训练相结合可能通过增加左心室收缩功能来增加中心血压。

2. 所有参与者(剑道运动员组和对照组)的中心脉压(cPP)与心搏量指数(SVI)(a)和dP/dTmaxb)之间的关系。

总之,剑道运动员组的中枢血压(cSBPcPP)显著高于对照组。剑道运动员组SVIdP/dTmax均显著高于对照组,但AP无显著性差异。SVIdP/dTmax与中心血压呈显著正相关。这些结果表明,习惯性剑道训练可使中枢血压升高,这与常规剑道训练引起的左心室顺应性和前向压力波有关,而与反射波无关
