The findings indicated the followings: 1) the calm heart rate increased in the early period of altiplano training, and then decreased as the body had adapted; 2) in alti-plano training, the hypoxia environment could boost the increase of blood serum cTnT; 3) in altiplano training, the double stimulation of hypoxia and training could cause the significant decrease of ECG ΣT/R, therefore, the change of the ECG ΣT/R value in altiplano training should be watched closely, and timely and effectively measures should be taken.
