Abstract

We have examined the effect of two beta-fibrinogen gene promoter polymorphisms (-455G>A and -854G>A) on the Fibrinogen response to severe exercise in a croup of male army recruits undergoing basic training. Fibrinogen was measured pre-training and again serially after severe 48 h final military exercise (FME). Out of 884 subjects, 762 completed training of whom 250 were selected for post-FME study. Fibrinogen levels (g/l) were significantly elevated over baseline levels 2, 48 and 96 h after FME, representing increases of 15.7%, 3.4% and 7.6% (p lt 0.005; p = 0.05 and p lt 0.005 respectively), with higher levels in -455A allele carriers than genotype -455GG: 3.17 +/- 0.05 vs. 2.94 +/- 0.05 (p lt 0.001), 2.86 +/- 0.05 vs. 2.60 +/- 0.05 (p lt 0.0005) and 2.98 +/- 0.06 vs. 2.69 +/- 0.06 (p lt 0.0005) at 2, 48 and 96 h respectively. There was no effect of the -854G>A polymorphism on fibrinogen, even after taking, into account beta-fibrinogen -455 genotype. Thus the fibrinogen -455G>A polymorphism influences fibrinogen levels following exercise. The effect of genotype might be clinically relevant at times of hyperfibrinogenaemia such as following an acute inflammatory response.
