Study on the effect of swimming on body composition and metabolism of serum lipids in the elderly. Select who frequently took part in winter swimming in 50 people aged 60~69 years for swimming in groups of older per-sons,and selected peer group system participating in physical exercise in healthy elderly 50-free control group, body composition and blood test. And control group compared to,swimming group of elderly,thin weight,and mus-cle volume,and body total water,and protein quality,and waist hip than( WHR),and high-density fat protein ( HDL-C)content were obviously increased,mineralsare obviously increased and fat percentage,and obesity rate, and total cholesterol( TC),and glycerol three ester( TG)and low density fat protein( LDL-C)content were obvi-ously reduced;and age,and height,and weight,and body quality index( BMI),and ratio of extra-cellular fluid and other indicators had no significant difference. The system of winter swimming exercise improves body composi-tion and serum lipid metabolism in the elderly.%探讨冬泳对老年人身体成分和血脂代谢的影响。选取经常参加冬泳的50名年龄在60~69岁的老年人为冬泳组，同时选取同年龄组无系统参加体育锻炼的健康老年人50名为对照组，测试身体成分和血脂。结果与对照组相比，冬泳组的老年人的骨骼肌肉量、蛋白质量、腰臀比（ WHR）、高密度脂蛋白（ HDL-C）和矿物质含量均明显升高；而脂肪量、肥胖率、总胆固醇（ TC）、甘油三酯（ TG）和低密度脂蛋白（ LDL-C）含量均明显降低；而年龄、身高、体重、身体总水分、身体质量指数（ BMI）等指标无明显差异。系统的冬泳锻炼能改善老年人的身体成分和血脂代谢。
