Selected genetic polymorphisms and plasma coagulation factor VII changes with exercise training.
We assessed the effects of coagulation factor VII (FVII) gene polymorphisms, lipid-related polymorphisms, and exercise training-induced plasma lipoprotein lipid changes on FVII level changes with exercise training in middle- to older-aged men and women. Forty-six healthy sedentary men and women were stabilized on a low-fat diet and then underwent baseline testing, 6 mo of endurance exercise training, and final testing. Plasma FVII-Ag levels decreased with exercise training (106.7 +/- 1.4 vs. 104.2 +/- 1.6%, P = 0.005). There were no significant differences in FVII-Ag changes with exercise training between -323 (0/10 bp)/-401 (G/T) haplotype or -402 (G/A) genotype groups. FVII-Ag changes with training were not correlated with changes in plasma lipoprotein lipids. In linear regression analyses, FVII-Ag changes with training remained significant after adjusting for training-induced plasma lipoprotein lipid changes (P = 0.01). FVII changes with training were associated with apolipoprotein E genotype (P = 0.012); this relationship was still evident after adjusting for training-induced plasma lipoprotein lipid changes (P = 0.047). FVII changes with training also were significantly associated with human ATPase binding cassette-1 genotype (P = 0.018); this relationship persisted after accounting for the effect of the training-induced plasma lipoprotein lipid changes (P = 0.045). We conclude that plasma FVII-Ag changes with exercise training are more closely related to selected lipid-related genotypes than FVII gene promoter variants.
