  1. Effects of physical activity and diet on lipoprotein (a) : Lipids and lipoproteins in diet and exercise.

    Article - En anglais

    Lipoprotein (a) [p (a) repre-sents a class of lipoproteins with some structural similarity to low density lipoprotein (LDL), but containing a unique apoprotein, apoprotein (a).

    First reported in 1963, Lp (a) is now considered to have an independent role in the development of atherosclerotic lesions.

    The level of Lp (a) in the blood is under strong genetic influence and does not appear to be alterable by lifestyle factors known to influence other lipoproteins.

    Regular moderate exercise has been shown to favorably alter other lipoproteins, and recent attention has focused on whether Lp (a) level can be influenced by physical activity.

    Current data from cross-sectional and intervention studies show little effect of moderate exercise on serum Lp (a) concentration.

    One possible exception may be an elevation of serum Lp (a) concentration in adult endurance and power athletes who exercise intensely on a daily basis.

    However, not all studies have taken into account possible racial or ethnic differences in Lp (a) concentrations and the skewed distribution observed within most populations.

    Standard dietary intervention such as a low fat diet recommended for weight loss and control of other blood lipids has little effect on serum Lp (a) level.

    At present, serum Lp (a) concentration does not appear to be significantly altered by realistic dietary changes and moderate physical activity as recommended for health. (...)
