Abstract

Background: Homocysteine, ﬁbrinogen and C-reactive protein (CRP) are three independent factors that independently and strongly predict the cardiovascular risks. Objectives: Thepurposeof thisstudywastoevaluatetheacuteandchronicresponsesof thesecardiovascularriskfactorsfollowing physical activity in overweight healthy inactive middle-aged men. Methods: Thesubjectsincluded21healthyinactivementhatwereassignedintotwogroupsof experimental(N=11)andcontrol(N = 10). The exercise protocol consisted of circuit resistance exercise (one session protocol) with intensity of 35% of 1RM; endurance training protocol lasting for 12 weeks (three sessions a week) and running exercise with intensity of 75% to 85% of maximum heart rate. Bloodsamplingsweretakeninpretestandposttest. Thedatawasusedusingpairedandindependentsamples t -testwereused for statistical analysis of data. Results: TheresultsindicatedthattherewasasigniﬁcantincreaseinhomocysteineandCRPfollowingcircuitresistanceexercise(P ≤ 0.05)whilenosigniﬁcantchangewasfoundinﬁbrinogeninexperimentalgroupafterexercise(P> 0.05). Additionally,thelevels of CRP and homocysteine were signiﬁcantly decreased after three months of aerobic exercises, (P ≤ 0.05) however no signiﬁcant change of ﬁbrinogen was observed (P > 0.05).

身体活动对超重男性心脏病发作新危险因素的急性和慢性影响

背景:同型半胱氨酸、纤维蛋白原和c反应蛋白(CRP)是三个独立的、独立且强烈预测心血管危险的因素。目的:本研究的目的是评估超重、健康、无运动的中年男性在运动后心血管危险因素的急性和慢性反应。方法:21例健康激活者分为实验组(N=11)和对照组(N= 10)。运动方案包括循环阻力运动(一次运动方案)，强度为1RM的35%;耐力训练方案持续12周(每周三次)，跑步运动强度为最大心率的75%至85%。Bloodsamplingsweretakeninpretestandposttest。采用配对样本和独立样本t检验对数据进行统计分析。结果:实验组运动后同型半胱氨酸和crp显著升高(P≤0.05)，而纤维蛋白原无显著变化(P> 0.05)。有氧运动3个月后CRP、同型半胱氨酸水平显著降低(P≤0.05)，而纤维蛋白原水平无显著变化(P > 0.05)。结论:尽管在不运动的中年男性中，动脉粥样硬化炎症过程似乎比凝血过程对运动更敏感，但需要更多的研究来做出关键的决定。
