太极拳锻炼对肥胖老年人肠道益生菌和血脂代谢影响的相关性研究

为探讨太极拳练习对肥胖老年人肠道益生菌和血脂影响的相关性,本研究对为期一年太极拳练习的肥胖老年人肠道益生菌中的肠嗜酸杆菌、乳酸杆菌和双歧杆菌和血清甘油三脂(TG)、总胆固醇(TC)、低密度脂蛋白(LDL-C)和高密度脂蛋白(HDL-C)进行定期检测。结果表明:与3个月时相比,6个月、9个月和12个月时的肠嗜酸杆菌、乳酸杆菌和双歧杆菌数量均明显增加,血清TC、TG和LDL-C浓度明显降低,HDL-C浓度明显升高,且均呈现明显的练习时间依赖性,即太极拳练习时间越长,肠道益生菌和血脂改善越明显。肠道益生菌可以通过多种途径明显加强胆固醇的转化利用,改善血脂代谢,提示肠道益生菌数量增加可能是太极拳练习改善肥胖老年人脂代谢的生物学机制之一。

Correlational research on the effect of Taijiquan exercise on intestinal probiotics and blood lipid of obese old people

To explore the correlation of intestinal probiotics and blood lipid of obese old people who practice Taijiquan for one year,the intestinal probiotics,including bacillus acidophilus,actobacillus casei and bacillus bifidus and the blood lipids,including TG,TC,LDL-C and HDL-C are periodically measured.The results are as follows:compared with 3-month group,the quantity of bacillus acidophilus,actobacillus casei and bacillus bifidus and the concentration of HDL-C increase significantly in the groups of 6-month,9-month and 12-month;the concentration of TG,TC and LDL-C also decrease obviously.There is an obvious connection between these data and practice time:the longer one practices Taijiquan,the more obviously the intestinal probiotics and blood lipid will be improved.The intestinal probiotics can significantly strengthen the transformation of cholesterol and improve the metabolism of blood lipid.It indicates that the improvement of intestinal probiotics’ quantity is one of the biological mechanisms,with which Taijiquan can improve blood lipid metabolism of obese old people.
