PHYSIOLOGICAL VARIATIONS OF LPA(I), HDL(2 ), AND PRINCIPAL LIPID MARKERS IN SPORTSMEN

An original approach of the influence of physical activities on lipid metabolism is presented in this work : the authors studied the physiol ogical variarions of tire lipoparticle LpA(I) high-density lipoprotein subfraction HDL(2) and the most important lipid markers in serum of a presumably healthy population of 55 high-level sportsmen. They were 1 8-45 years old and practised endurance sports, whether individual (cyc ling, long-distance running), or collective activities (soccer, basket ball). The authors observed an important increase of LpA(I) (+20%, p < 0.001) and C-HDL(2) (+23.3%, p < 0.01) after an intense physical acti vity (CK = 430 +/- 312 U/l); they also found a good correlation elario n between LpA(I) and HDL(2) (r = 0.85, p < 0.0001) and between LpA(I) and CK ( (r = 0.62, p < 0.001).
