Abstract/OtherAbstract:
1. Total plasma cholesterol, high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), noradrenaline, haematocrit, haemoglobin and heart rate were measured in blood sampled from an antecubital vein in nine volunteers after 1 min standing and at intervals up to 1 h following 5 min of vigorous bicycle exercise. 2. Heart rates and plasma noradrenaline levels rose substantially immediately following exercise and gradually returned toward baseline levels 60 min post-exercise. 3. Total plasma cholesterol levels rose by 24% immediately post-exercise and slowly returned to baseline levels 60 min post-exercise. Similar changes were observed for LDL-C (20.2%) and HDL-C (27.7%). As a result, LDL:HDL ratios did not alter. 4. These changes in total plasma cholesterol, HDL-C and LDL-C were explained by changes in plasma volume that occurred as a consequence of vigorous exercise. 5. Changes in plasma volume may be a mechanism by which some environmental factors such as stress are associated with elevated plasma cholesterol levels.
