| 摘 要： | 目的:探讨肥胖儿童少年红细胞膜PS外翻水平和ATP酶活性及运动减肥干预对其的影响.方法:对64名肥胖儿童少年(按体脂百分比分为轻、中和重度肥胖组共3组)进行4周有氧运动减肥,采用流式细胞术测定红细胞膜PS外翻,干预前后进行血脂、PS外翻及Na K+ - ATPase和Ca2+ Mg2+- ATPase酶活性的测定.结果:运动干预前轻度肥胖组PS外翻与其他2组肥胖者之间存在显著性差异(P≤0.05),HDL仅在轻度组和重度组之间存在显著性差异；运动干预后Na+ K+ -ATPase活性显著增加(P≤0.05),CE2+ Mg2+- ATPase活性虽有增加,但未呈显著性水平；运动干预后PS外翻虽然有所下降,但无显著性差异.结论:脂代谢紊乱的初期,膜PS外翻可能比血脂指标更能体现肥胖的发展.有氧运动减肥能显著增加红细胞膜Na+ K+ - ATPase活性,改善红细胞膜PS外翻水平,但后者对运动干预的效应滞后于血脂变化.
