[Physiological variations of LpA1, HDL2 and principal lipid markers in athletes].
An original approach of the influence of physical activities on lipid metabolism is presented in this work: the authors studied the physiological variations of the lipoparticle LpA1, high-density lipoprotein subfraction HDL2 and the most important lipid markers in serum of a presumably healthy population of 55 high-level sportsmen. They were 18-45 years old and practised endurance sports, whether individual (cycling, long-distance running), or collective activities (soccer, basketball). The authors observed an important increase of LpA1 (+20%, p < 0.001) and C-HDL2 (+23.3%, p < 0.01) after an intense physical activity (CK = 430 +/- 312 U/l); they also found a good correlation between LpA1 and HDL2 (r = 0.85, p < 0.0001) and between LpA1 and CK (r = 0.62, p < 0.001).
