The au-thors revealed the following findings: 1)there was a significant difference between WBC changes in different geno-types (P<0.10), and there was a significant difference between M Retic# changes; 2)there was a significant differ-ence between MCV and MCH changes at the rs6715787 polymorphic locus in different genotypes (P<0.01, P<0.05). The said findings indicated the followings: 1)the rs7598371 polymorphic locus of the HIF-2a/EPAS1 gene is correlative with WBC and M Retic# before and after HiHiLo training, can be used as a molecular marker to pre-dict WBC and M Retic# changes during HiHiLo training; 2)the rs6715787 polymorphic locus of the HIF-2a/EPAS1 gene is correlative with MCV and MCH before and after HiHiLo training, can be used as a molecular marker to predict MCV and MCH changes during HiHiLo training. |
