Lipoprotein (a): effect of detraining.

Plasma levels of lipoprotein (a), total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, apo-protein Al and apoprotein B were evaluated for 8 long-distance runners during the XXIII New York Marathon, with blood samples being taken before and after the race, and after one month of detraining. After detraining lipoprotein (a) increased significantly both with respect to basal values and especially with respect to immediately post-race values. Negligible and predictable modifications of the other metabolic parameters evaluated, were observed. No correlation was found between lipoprotein (a) and the anthropometrical data and metabolic parameters considered.
