探讨了有氧运动训练后体脂和有氧适能的变化对血脂变化的贡献。样本包括295名男性（77名黑人，218名白色）和355名女性（131名黑人，224名白色），年龄在17至65岁之间，来自遗产家庭研究。参与者在基线和20周的监督运动训练后在自行车测力计上进行测量，通过水下称重确定身体脂肪量（FM，以千克为单位），并通过自行车测力计评估有氧健身（最大摄氧量，Vo（2 max），以毫升/分钟为单位）。血脂测量包括空腹血浆高密度脂蛋白胆固醇（HDL-C）、HDL 2-C、HDL 3-C、低密度脂蛋白胆固醇（LDL-C）、总胆固醇（CHOL）、CHOL/HDL和甘油三酯（TG）水平。通过对个体血脂的h评分进行主成分分析，得出复合血脂变化指数（LCI）。运动训练后Vo（2 max）平均增加17.5%，FM平均减少3.3%。偏相关性，年龄控制，Vo（2 max）的绝对变化和血脂的变化之间的一致性低，不显着。另一方面，FM的绝对变化显著（P < .05）与HDL-C的变化相关（r =-0.23），HDL2-C（r =-0.17）和CHOL/HDL在男性中，与LDL-C（r = 0.24）和LCI（r =-0.27）的变化以及女性中LDL-C（r = 0.22）、CHOL（r = 0.19）和CHOL/HDL（r = 0.15）和LCI（r =-0.19）的变化相关。前向逐步回归证实，FM的变化是一个更好的预测血脂变化的变化比Vo（2 max）的变化，进入作为一个预测在男性和女性的8个回归的4。男女都有变化。Vo（2 max）的变化在任何回归中都没有作为重要的预测因素。此外，男女都有。在任何回归中，Vo（2 max）的变化均未作为显著预测因素输入。此外，Vo（2 max）在任何回归中均未作为显著预测因子进入。此外，Vo（2 max）变化的上四分位数和下四分位数之间的LCI无差异。另一方面，FM变化的低四分位数和高四分位数之间存在显著差异。在任何关系中都没有观察到种族效应，除了种族是男性和女性TG变化的重要预测因素。总之，与有氧运动训练相关的血脂变化似乎与有氧健身本身的变化无关;相反，它们与身体肥胖的变化有弱至中度的相关性。Copyright（C）2001 by W.B.桑德斯公司
The contribution of changes in body fatness and aerobic fitness to changes in blood lipids after aerobic exercise training was investigated. The sample included 295 men (77 black, 218 white) and 355 women (131 black, 224 white), aged 17 to 65 years, from the HERITAGE Family Study. Participants underwent measurements at baseline and after 20 weeks of supervised exercise training on a cycle ergometer, Body fat mass (FM, in kilograms) was determined by underwater weighing, and aerobic fitness (maximal oxygen uptake, Vo(2max) in milliliters per minute) was assessed by cycle ergometry. Blood lipid measurements included fasting plasma levels of high-density lipoprotein cholesterol (HDL-C), HDL2-C, HDL3-C, low-density lipoprotein cholesterol (LDL-C), total cholesterol (CHOL), CHOL/HDL, and triglycerides (TG). A composite lipid change index (LCI) was derived by subjecting the h scores for the individual blood lipids to principal components analysis. The exercise training was accompanied by a mean increase of 17.5% in Vo(2max) and a mean decrease of 3.3% in FM. Partial correlations, controlled for age, between absolute changes in Vo(2max) and changes in the blood lipids were consistently low and nonsignificant. On the other hand, absolute changes in FM were significantly (P < .05) associated with changes in HDL-C (r = -.23), HDL2-C (r = -.17), and CHOL/HDL (r =.24) and the LCI (r = -.27) in men and with changes in LDL-C (r = .22), CHOL (r =.19), and CHOL/HDL (r =.15) and the LCI (r = -.19) in women. Forward stepwise regression confirmed that the change in FM was a better predictor of changes in blood lipids than the change in Vo(2max), entering as a predictor in 4 of 8 regressions in both men and women. Change in in both men and women. Change in Vo(2max) did not enter as a significant predictor in any regression. Further, there were in both men and women. Change in Vo(2max) did not enter as a significant predictor in any regression. Further, there were Vo(2max) did not enter as a significant predictor in any regression. Further, there were no differences in LCI between the upper and lower quartiles of Vo(2max) change. On the other hand, there were significant differences between the low and high quartiles of FM change. No race effects were observed in any of the relationships, except that race was a significant predictor of changes in TG in both men and women. In conclusion, changes in blood lipids associated with aerobic exercise training do not appear to be related to changes in aerobic fitness per se; rather, they are weakly to moderately associated with changes in body fatness.
