[Research on the relation between ACE gene I/D polymorphisms and sensitivity to endurance training of Han nationality...

In order to seek the marks of the genes, the relation between the influence of endurance training on aerobic ability and ACE Gene I/D Polymorphisms were studied.

102 army recruits of Han nationality from North China for an 18 week en durance training of 5000m distance. Their VO2(max), VT and the left ventricular structure and function were measured before and after the training. We also tested their ACE Gene I/D Polymorphisms with PCR-AFLP method.

The compliance of VO2(max), VT and left ventricular structure and function had improved after the training; the deltaVO2(max) of ID and II type was obviously higher than that of DD type (P < 0.05); there was obviously diference of deltaVO2(VT) in different ACE genotype (P < 0.05), the deltaVO2(VT) of type II was obviously higher than that of DD type (P < 0.05).

I allele has obviously hereditary advantage on the sensitivity to aerobic training in VO2(max) and VT, and type II has relation on the sensitivity to aerobic training in VT; there is no relation between I/D polymorphism and the sensitivity to aerobic training on the structure and function of left ventricle.
