健美操运动对中年人血脂成分和高分子量脂联素的影响

Effects of Aerobic Exercise on Lipid Profiles and High Molecular Weight Adiponectin in Middle-aged Workers

目的研究健美操运动对中年人群血脂成分和高分子量脂联素的影响,以及高分子量脂联素与身体成分和脂代谢的相关关系。方法对志愿者进行6个月的运动干预,并于实验前后测试体质量、BMI、体脂肪百分比、血脂成分及生活质量等指标。结果通过6个月的健美操运动,体脂肪率、甘油三酯、总胆固醇、高密度脂蛋白及低密度脂蛋白均有显著性改善;高分子量脂联素和BMI、低密度脂蛋白、空腹血糖值呈显著的负相关关系;高分子量脂联素和高密度脂蛋白有显著的正相关关系。结论 6个月的健美操运动可以改善中年人的身体成分及血脂水平;使中年人的高分子量脂联素浓度呈逐渐上升趋势,促进高分子量脂联素的良性变化;高分子量脂联素的变化与BMI的变化密切相关。

Objective The metabolic syndrome is characterized by the accumulation of several metabolic risk factors. It is important to improve physical activity and dietary habits to reduce the risk of cardiovascular disease in humans. Methods The study participants participated in a weekly aerobic exercise program that included a session composed of a brief meeting, warm -up exercises, and primary exercises （low and high impact, stretch, muscle training, and cooling down）. To evaluate the effect of this intervention we measured body fat composition, holding power, and quality of life assessment. Blood tests were also carried out before and every 6 months during the study. Results Of the 40 participants enrolled in the exercise group, 35 （87.5 % ） completed the 24 -week program. The control group consisted of 40 subjects, 33 （82.5%） of whom were available for follow - up at the end of the 24 - week study period. In the exercise group, weight, body fat percentage, waist circumference, the World Health Organization quality of life 26 （ WHO - QOL 26） score, triglyceride, total cholester- ol, high density lipoprotein cholesterol and low density lipoprotein cholesterol had improved significantly at the end of six months. Conclusion Aerobic exercise led to an improvement in body composition and lipid profiles. High molecular weight adiponectin concentrations tended to improve compared with pre -aerobic exercise levels.
