Two age groups (young and old, n = 12) matched for physical fitness and two physical fitness groups (high and old, n = 12) matched for age participated in a four month physical fitness programme. Blood samples were drawn at four stages of metabolic stress at the pre-test and five stages at the post-test. The blood samples were analyzed by colorimetric methods for total cholesterol and free cholesterol. Statistical analysis revealed that: (1) Short-term exercise increased total cholesterol, free cholesterol, and the percent free cholesterol from the resting state to the submaximal and maximal exercise states. (2) There was no change in free serum cholesterol from the pre- to post-tests. (3) The high-fit group, compared with the low-fit group, had a lower free cholesterol level but had similar percent free cholesterol values. (4) There was no significant difference between age groups for either total serum cholesterol, free cholesterol, or the percent free cholesterol levels.
两个在体能方面相匹配的年龄组（年轻组和老年组，每组n = 12）以及两个在年龄方面相匹配的体能组（高体能组和低体能组，每组n = 12）参与了一项为期四个月的体能训练计划。在测试前的四个代谢应激阶段以及测试后的五个阶段采集血样。采用比色法对血样进行总胆固醇和游离胆固醇分析。统计分析结果显示：（1）短期运动使总胆固醇、游离胆固醇以及游离胆固醇百分比从静息状态到次最大和最大运动状态均有所增加。（2）从测试前到测试后，血清游离胆固醇没有变化。（3）与低体能组相比，高体能组的游离胆固醇水平较低，但游离胆固醇百分比值相似。（4）在总血清胆固醇、游离胆固醇或游离胆固醇百分比水平方面，年龄组之间没有显著差异。
