Echocardiographic Assessment Of Heart Performance During Increasing Load Exercise In WuJing-Soldiers

The performance of heart plays an important role in sports and exerciseswhich at the same time affect the feature and function of the hearts.WuJing-soldiers' strong is of importance in national defence and stabilization.The military discipline make them strong.Echocardiographic examination(UCG) is newly developed technology in the late 30 years,which enjoys popular recognition for its effect in clinical and basic study.Our experiments use this technology to study the difference of the heart of some soldiers of the 19th WuJing-detachment in BeiJing.The main study and conclusion lies below:1 .The three monthes regular military discipline brings more enlargement to new soldiers' left ventricular internal dimensions than untrained health men's,but less than the older soldiers having been trained for two years.Such indexes as ESD> ESV\ EDD, EDV show distinct difference between the new and the old soldiers.2.In term of the wall thickness of ventricular,there is little difference.The indexes,such as PWd. PWs, IVSTd and IVSTs show it.3.The cardiac output show distinct deference which is resulted from not heart rate but stroke volume(SV).Comprehensive analysing to MVCF> FS - EF et discloses that myocardium contract ability results to it.Furthermore,the old soldiers' hearts have better adaptability to stimulation.4.Because of little statistic difference between the new soldiers and the old ones' heart rate and cardiac index,we advise: keep training in more and higher intensity 3 monthes later,it will make better to the hearts..5.Military training mainly by endurance,combining with many other kinds brings obvious enlargement to ventricular volume but little thickness of ventricle wall.We suggest adding some high intensity and strength and anaerobic endurance exercise to the main aerobic training in order to improve the ejection ability.
