abstract = {Problem statement: Establishment of upper normal limits of physiological hypertrophy in
response to physical training is important in the differentiation of physiological and pathological left
ventricular hypertrophy. The goal of our study was to investigate the normal upper limits of cardiac
dimensions in elite athletes in Jordan in different types of sports (8 soccer players, 8 sprinters, 8 long
distance runners, 6 weight lifters, 6 body builders). Approach: A total of 36 male athletes age 25±5 years
of age, representing various sports were examined using standard two-dimensional guided M-mode
and Doppler echocardiography to evaluate cardiac dimensions. Results: Results showed that 36 male
athletes, 24 (66.6%) presented with LVEDD ≥50 mm with an upper limits of 53.4 mm sd 3.15, only
12 subjects (33.3%) presented with wall thickness values ≥11 mm, sd 0.53. None were found to have
maximum wall thickness greater than 13 mm. There was a significant difference (p},
