Molecular biology method for predicating endurance potentials of excellent ice-snow sportsmen

Abstract

The invention discloses a molecular biology method for predicating the endurance potentials of excellent ice-snow sportsmen, which can be used for inquiring the relationship between the I/D (kininase II gene insertion/deletion) polymorphisms of ACE (angiotensin-converting enzyme) and the endurance potentials of the excellent ice-snow sportsmen. Lots of research results indicate that the genetic I/D polymorphisms are associated with the aerobic endurance of the sportsmen, are the key factors for judging the aerobic endurance quality of a human body, and affect the optimal level of the aerobic endurance quality of a human body and the sensitivity of a human body for endurance training; and the genes mainly affect the cardio-pulmonary function of a human body, and thus affecting the aerobic endurance quality of a human body. In consideration that the ACE genes are related to the aerobic endurance of movements, researches for the distribution of the genes in the excellent ice-snow sportsmen by applying the molecular biology method have important theoretical significance for determining the relevance between the genes and endurance-type ice-snow sports, and lay the foundation of future molecular selection by applying the molecular biology method.

Description

technical field [0001] The present invention relates to a molecular biological method for predicting the endurance potential of excellent ice and snow athletes, specifically by analyzing the polymorphism of ACE (Angiotensin-converting enzyme) I / D (kininase II gene insertion / deletion type), thereby Learn how polymorphisms in the ACE gene affect the gift of exceptional endurance. This invention belongs to the interdisciplinary field of basic life science, human genetic resources, molecular biology and sports science. Background technique [0002] ACE is a 20-peptide single-chain acid glycoprotein, which is a zinc-containing metallohydrolase, and its system name is peptidyl-dipeptide hydrolase or kininase II. ACE widely exists in various tissues of the body, mainly distributed in vascular endothelial cells (especially in pulmonary circulation), renal epithelial cells, etc. Bradykinin, a natural substrate of ACE, inhibits its biological activity by cleaving two hydroxyl-termin...
