Abstract

To document the possible influence of a single episode of maximal aerobic stress on the serum lecithin:cholesterol acyltransferase (LCAT) activity in subjects with differing histories of training, two groups of healthy male adults [controls (C), n = 18, 28.6 years, SD 5.2, 50.1 ml.kg-1.min-1 maximal O2 uptake (VO2max), SD 5.3; endurance trained athletes (T), n = 18, 31.4 years, SD 8.8, 65.0 ml.kg-1.min-1 VO2max, SD 2.8] were examined in a maximal aerobic stress test. In addition to the routine assessment of lipid status, LCAT activity was measured immediately before and after exercise. At rest nearly identical LCAT activity values were found in both groups: C 64.4 nmol.ml-1.h-1, SD 16.7 vs T 65.0 nmol.ml-1.h-1, SD 20.9. The post-exercise LCAT values induced by the maximal stress test increased significantly to (C) 95.7 nmol.ml-1.h-1, SD 23.5, +48.6%, P less than 0.001; (T) 83.5 nmol.ml-1.h-1, SD 24.3, +29.1%, P less than 0.01. Neither the pre nor the postexercise individual LCAT activity values showed any significant correlation to the corresponding data on physical performance.

摘要

为了记录单次最大有氧应激对不同训练史受试者血清卵磷脂胆固醇酰基转移酶（LCAT）活性的可能影响，对两组健康成年男性[对照组（C），n = 18，28.6岁，标准差5.2，最大摄氧量（VO2max）为50.1 ml·kg-1·min-1，标准差5.3；耐力训练运动员（T），n = 18，31.4岁，标准差8.8，VO2max为65.0 ml·kg-1·min-1，标准差2.8]进行了最大有氧应激测试。除了常规评估血脂状况外，还在运动前后立即测量了LCAT活性。静息时两组的LCAT活性值几乎相同：C组为64.4 nmol·ml-1·h-1，标准差16.7，T组为65.0 nmol·ml-1·h-1，标准差20.9。最大应激测试诱导的运动后LCAT值显著增加至（C组）95.7 nmol·ml-1·h-1，标准差23.5，增加48.6%，P<0.001；（T组）83.5 nmol·ml-1·h-1，标准差24.3，增加29.1%，P<0.01。运动前和运动后的个体LCAT活性值与相应的体能数据均无显著相关性。
