Abstract
Title: Resilience to orthostasis and haemorrhage: A study of common genetic and conditioning mechanisms
The objective of this study was to examine acquired and innate vagal mechanisms that protect against physical challenges and haemorrhages. These include examining change in heart rate variability in response to orthostatic challenge, platelet count (PLT), mean platelet volume, and single-nucleotide polymorphisms in genes. Regular physical training of athletes indirectly modifies the genetic predisposing effects of some haemostatic factors on vagal tone and reactivity.
Keywords
genetic predisposition, heart rate variability, haemostasis system at athlets and non-athlets
Summary

Abstract in full:

A major challenge presently is not only to identify the genetic polymorphisms increasing risk to diseases, but to also find out factors and mechanisms, which can counteract a risk genotype by developing a resilient phenotype. The objective of this study was to examine acquired and innate vagal mechanisms that protect against physical challenges and haemorrhages in 19 athletes and 61 non-athletes. These include examining change in heart rate variability (HF-HRV; an indicator of vagus
activity) in response to orthostatic challenge, platelet count (PLT), mean platelet volume (MPV), and single-nucleotide polymorphisms in genes that encode several coagulation factors, PAI-1, and MTHFR. Individual differences in PLT and MPV were significant predictors, with opposite effects, of the profiles of the HF-HRV changes in response to orthostasis. Regular physical training of athletes indirectly (through MPV) modifies the genetic predisposing effects of some haemostatic factors (PAI-1 and MTHFR) on vagal tone and reactivity. Individual differences in vagal tone were also associated with relationships between Factor 12 C46T and Factor 11 C22771T genes polymorphisms.
This study showed that genetic predispositions for coagulation are modifiable. Its potential significance is promoting advanced protection against haemorrhages in a variety of traumas and injuries, especially in individuals with coagulation deficits.
