AB  - BACKGROUND: Ice hockey is a high-intensity dynamic sport for which competitive 
      athletes train for longer than 20 hours each week for several years. The 
      cumulative time of myocardial exposure to hemodynamic stress affects cardiac 
      remodeling. However, the intracardiac pressure distribution of the elite ice 
      hockey athletes' heart during adaptation to long-term training remains to be 
      explored. This study aimed to compare the diastolic intraventricular pressure 
      difference (IVPD) of the left ventricle (LV) between healthy volunteers and ice 
      hockey athletes with different training times. METHODS: Fifty-three female ice 
      hockey athletes (27 elite and 26 casual) and 24 healthy controls were included. 
      The diastolic IVPD of the LV during diastole was measured by vector flow mapping. 
      The peak amplitude of the IVPD during isovolumic relaxation (P0), diastolic rapid 
      filling (P1), and atrial systole (P4); the difference in the peak amplitude 
      between adjacent phases (DiffP01, DiffP14); the time interval between the peak 
      amplitude of adjacent phases (P0P1, P1P4); and the maximum decrease rate in 
      diastolic IVPD were calculated. Differences between groups, as well as 
      correlations between hemodynamic parameters and training time, were analyzed. 
      RESULTS: Structural parameters of the LV were significantly higher in elite 
      athletes than in casual players and controls. No significant difference in the 
      peak amplitude of the IVPD during the diastolic phase was found among the three 
      groups. The analysis of covariance with heart rate as a covariate showed that 
      P1P4 in the elite athlete and casual player groups was significantly longer than 
      that in the healthy control group (p < 0.001 for all). An increased P1P4 was 
      significantly associated with an increased training year (beta = 4.90, p < 0.001). 
      CONCLUSIONS: The diastolic cardiac hemodynamics of the LV in elite female ice 
      hockey athletes could be characterized by a prolonged diastolic IVPD, and P1P4 
      prolonged with an increase in the training years, reflecting a time-domain 
      adaptation in diastolic hemodynamics after long-term training.
