The Influence Of The Short-term Training Before The Match On The Excellent Male Athletes' Doppler Echocardiogram Of Anyang Teachers' College

As an uninjured examination method,the Doppler echocardiogram is more and more used to check up the heart of excellent athletes.But all is the research long-term training to the athlete heart shape,the structure and the function influence,but whether does the short-term movement train causes the athlete heart shape structure to change,at present has not seen the report..This study,taking college students of RE.Department of Anyang Teachers' College as objects of study,who were chosen to be athletes in the 14^th College Students Sports Meeting of HeNan Province,discusses that short-term training has influenced on their Doppler echocardiogram.Thus to instructs the movement training to provide the theory basis.This experiment is made use of the color Doppler ultrasonic to compare the difference of 18 male athletes' hearts shapes and functions before the training and after it,who are prepare to take part in the 14^th College Students Sports Meeting of HeNan Province.These 18 athletes are divided into two groups:Strength Group and Endurance Group.Each group has 9 persons.Before the match,they have trained for three months.Every tester of the two groups is measured separately the heart shape and function items in the resting and master's test curve,and bicuspid valve, tricuspid valve,aorta and pulmonary blood flow frequency before the training and after it.The results show:1) After the short-term training,the athletes' hearts shape and structure in Endurance Group and Strength Group both changed apparently.Between them,Endurance Group changed more:not only left ventricle cavity shin enlarged,but also the wall of left heart thickened slightly,the weight of left cardiac muscle increased apparently.But Strength Group changed less:only the wall of left heart thickened and the weight of it increased slightly.2) After the short-term training,the athletes' hearts functions in both of two groups changed. Between them,the indexes of HR,SV,EDV and so on in two groups both increased obviously,but the extends of increasing are different between the two groups;%ΔD both of groups also increased but not clear,but the indexes of EF,ESV,CO and so on have not changed.3) From the color Doppler ultrasonic frequency,the athletes' hearts contraction and diastole function in Endurance Group and Strength Group both get strengthen.But endurance training influenced on left heart and right heart contraction function more than strength training did,however the influence on left heart and right heart diastole function are similar between two groups.
