摘要:
      摘要 目的:探究饮食控制结合12周中等强度和低强度抗阻训练,对高脂血症中年女性患者餐后血脂的影响。 方法:将60例高脂血症中年女性患者随机分为中等强度(60%一次最大重复负荷)训练组(MG,n=15),低强度(30%一次最大重复负荷)训练组(LG,n=15),饮食控制组(AG,n=15)以及对照组(CG,n=15)。两训练组均进行为期12周抗阻训练(3—4d/周,8节/d,3组/节,10—12次/组,组间休息1min,每天训练前后15min热身与放松),介入期间控制饮食,抗阻运动为包含上下肢和躯干的大关节,共8节动作的训练。AG仅进行饮食控制,CG保持原有生活状态。在治疗开始前和最后一次训练结束第2天中午饭后3h后测定其血脂,分析血液中甘油三酯(TG)、胆固醇(TC)、高密脂蛋白(LDL-C)、低密脂蛋白(HDL-C)含量,进行比较。 结果:治疗前四组患者血液中TC、TG高于正常水平(P<0.05),组间差异无显著性意义(P>0.05);治疗后与CG相比,其他三组餐后TC均下降,但无显著性意义(P>0.05),组间差异不明显(P>0.05);治疗后与CG相比,其他三组TG均明显下降(P<0.05),其中MG下降强于LG(P<0.05),AG下降但无显著性意义(P>0.05);治疗后两训练组HDL-C升高有显著性差异(P<0.05),AG HDL-C升高无显著性差异(P>0.05),组间差异不明显(P>0.05);治疗后与CG相比,两训练组LDL-C均明显下降(P<0.05),MG下降更明显(P<0.05),AG下降但无显著性意义(P>0.05)。 结论:饮食控制结合中、低强度抗阻训练都能有效降低餐后TG、LDL-C水平和升高HDL-C水平,其中与中等强度抗阻训练结合对餐后血脂影响更明显。

Abstract:
      Abstract Objective: To determine the influence of twelve-week low-intensity and moderate-intensity resistance exercise combined with alimentary control on postprandial lipemia (PPL) in middle-aged female subjects with hyperlipidemia. Method: Sixty middle-aged female subjects with hyperlipidemia were divided into four groups randomly, control group (CG), alimentary control group (AG), low-intensity exercise group (LG) and moderate-intensity exercise group (MG). Low-intensity (30% 1-repetition maximum) and moderate-intensity (60% 1-repetition maximum) resistance exercise combined alimentary control were performed respectively in LG and MG. Exercises contained 3 sets of 10—12 repetition of 8 exercises with a 1-min rest between sets were completed 3—4 times per week for 12 weeks. A 15-min warm-up and a finish exercise of equal time were implied. And alimentary control was kept during intervention except for CG. The venous blood samples were collected 3h postprandially and 1RMs of the objects were measured by resistance training equipment before and after the intervention. The contents of serum triglyceride (TG), cholesterol (TC), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) were detected. Result: Before intervention: Contents of TG and TC in subjects were abnormal and had no significant difference (P>0.05) in all 4 groups. TC in MG, LG and AG declined but showed no difference after intervention (P>0.05), no differences between 3 groups either (P>0.05). TG in MG, LG and AG descended after intervention (P<0.05) and MG was lower compared with LG (P<0.05), but in AG,TC increasing had no significance(P>0.05). HDL-C in MG and LG increased after intervention (P<0.05) and the increment of LG was lower compared with that in MG (P<0.05). LDL-C in MG, LG and AG decreased after intervention and decrement in LG was lower compared with that in MG (P<0.05). Conclusion: Resistance exercise combined alimentary control is effective in decreasing TG, LDL-C and the augment of HDL-C. Furthermore, moderate-intensity resistance exercise can induce more obvious effects on postprandial TG and LDL-C.
