Abstract:
Objective To investigate the relationship of cardiac function and ventricular structure with the training intensity and the periods lived in Tibet.Methods Sixty recruits to Tibet were selected and examined of their cardiac function,cardiac ventricular structure and the changes of elctrophysiology by color Doppler echocardiography and electro cardiogram.They were examined continuously in two years.After their training for three months together,they were divided into the different training intensity groups,Group A and Group B.The 30 recruits in Group A had high-intensity training,and the others in Group B had normal training.Results After three months,their cardiac function and ventricular structure had obvious difference in comparison with the level on plain( P 0.05 ).But there were obvious differences between in Tibet and on plain in the parameters of cardiac function and ventricular structure two years later( P 0.05 ).Conclusions Hypoxia can effect the cardiac function and ventricular structure directly.After three months in Tibet,cardiac function can fit the condition of hypoxia.The parameters of cardiac function are still less than those on plain.The right ventricules are bigger and the pulmonary arteries wider as the main character of the ventricular structure changes.The indexes of cardiac function showed no significant difference with the training intensity and the periods in Tibet.
