The echocardiograms of 41 top−class runners (8 males and 6 females sprint−trained, 15 males and 12 females endurance−trained) were recorded at the beginning and after 1, 2, and 3years of training. A one−way ANOVA and a linear regression analysis were conducted to determine changes and association between performance and LV values. Training resulted in an increase in performance and LV internal diameter at end−diastole (LVIDd) and decreases in end−diastolic interventricular septal wall thickness, and posterior wall thickness (PWTd). There were no significant differences in LV mass and LV ejection fraction (LVEF, %). The changes in PWTd were linked to enlargement of the LV. In athletes with unusual LV dilatation (>60mm), LVIDd was related to performance and LVEF was >50%. Maximal wall thickness was <13mm in all athletes. LV adaptations were independent of sex and type of training and related to the initial level of performance. We believe that LV enlargement in elite runners is a physiological adaptation and that the LVIDd is a predictor of running performance.
