A comparison of the influence of simple and complex @entity1735 ( @entity435 ) consumption on adipose tissue- and skeletal muscle- @entity5523 activity (AT-LPLA, SM-LPLA) was examined. Twenty male marathon runners were divided into two equal dietary groups: simple- @entity435 and complex- @entity435 . Half of the subjects in each group consumed either a low- @entity435 (15% energy [E] intake), or a mixed diet (50% @entity435 ) for 3 days. Immediately following this dietary period, the subjects consumed a @entity435 -rich diet (70% E intake) predominant in simple- @entity435 or in complex- @entity435 for an additional 3 days. Thereafter, all subjects returned to a normal mixed diet. Skeletal muscle biopsies, adipose tissue aspirations, and venous blood samples were obtained prior to dietary manipulation (PRE), upon completion of the 6 day diet (POST I), and 2 weeks after returning to a normal diet (POST II). The samples were analysed for AT-LPLA, SM-LPLA, serum insulin, and free @entity1718 (FFA), and blood @entity413 , and @entity880 . SM-LPLA fell 71% from PRE values of 0.39 +/- 0.30 mu mol.g-1.h-1 to POST I values of 0.11 +/- 0.09 mu mol.g-1.h-1 (means +/- SD) (p less than 0.05), after a complex- @entity435 diet. However, the simple- @entity435 diet did not alter SM-LPLA. AT-LPLA similarly decreased (p less than 0.05) after the complex- @entity435 diet, and no significant decrease was noted after the simple- @entity435 diet.(ABSTRACT TRUNCATED AT 250 WORDS)
