运动对景德镇中年女性血脂及脂蛋白代谢影响的研究

目的 探究不同形式、不同强度的运动对景德镇市中年女性血脂及脂蛋白代谢的影响。方法 对景德镇市45~60岁女性进行随机问卷调查，选取非高脂血症实验对象36人，随机分配到 A、B、C 三组，每组12人。A组为对照组。B、C运动干预组相对运动强度分别为47%和59%。运动频率5~7次/周、时间70 min/次，试验干预周期24周。结果 纵向比较:干预后B、C组均出现APOAⅠ升高，差异有统计学意义（P＜0.05）； HDL-CH、APOAⅠ/APOB升高，差异有统计学意义（P＜0.01）。干预后组间横向比较:B组与A组比较TG降低、APOB降低、 APOAⅠ升高，差异有统计学意义（P＜0.05）； HDL-CH、APOAⅠ/APOB升高，差异有统计学意义（P＜0.01），C组与A组比较 LDL-CH降低、APOAⅠ升高，差异有统计学意义（P＜0.05）， TG降低HDL-CH升高、APOAⅠ/APOB升高，差异有统计学意义（P＜0.01）。C组与A组比较各指标均无显著性差异。结论 中小轻度锻炼可以降低中年女性的血脂、改善脂代谢，但运动对中年女性脂代谢的影响主要取决于运动强度与运动形式无关。

Effect of Exercise on Lipid and Lipoprotein Metabolism of Middle-aged Women in Jingdezhen

Abstract:Objective To investigate the effects of different forms and intensity of exercise on lipid and lipoprotein metabolism of middle-aged women in Jingdezhen.Methods A randomized questionnaire survey was conducted among 45~60-year-old women in Jingdezhen.36 non-hyperlipidemic subjects were selected and randomly assigned to A,B and C groups of 12,each group.A group as control group.The relative exercise intensity of B and C exercise groups were 47% and 59% respectively.Exercise frequency of 5 to 7 times/week,time 70 min/times,the experimental intervention period of 24 weeks.Results Longitudinal comparison: after intervention, APOA Ⅰ increased in group B and C,the difference was statistically significant(P<0.05).HDL-CH、APOA/APOB increased significantly(P<0.01).Horizontal comparison among groups after intervention: In group B and group A,TG decreased,APOB decreased and APOA I increased.The difference was statistically significant(P<0.05).HDL-CH,APOA I/APOB increased,the difference was statistically significant(P<0.01),C group compared with A group LDL-CH decreased,APOA I increased,the difference was statistically significant(P<0.05).TG decreased the increase of HDL-CH and increased APOA I/APOB,and the difference was statistically significant(P<0.01).There was no significant difference between group C and group A.Conclusion Moderate and mild exercise can reduce blood lipid and improve lipid metabolism of middle-aged women,but the effect of exercise on lipid metabolism of middle-aged women mainly depends on exercise intensity and exercise form.
