| Abstract | Almost all the studies of athlete's heart have been carried out on adult and older adolescent players; hence the limited data on the cardiac response to exercise in the beginning of the active sports career in the youngest athletes. The study was designed to examine the physiological limits of left ventricle (LV) cavity size and wall thickness in elite footballers at the preadolescent age, it the beginning of the active sports career. Ninety-four highly trained male footballers (mean aged 12.85±0.84) competing in the Serbian Football League and 47 age-matched healthy male controls, aged 12-14, were enrolled in the study. All the echocardiographic findings were adjusted to BSA(-0.5), while left ventricle mass (LVM) was additionally adjusted to BSA(-1.5). Reference ranges were defined as values of 5-95th centile according to the mean values in both groups. The proportions of the footballers with LV dimensions outside expected ranges were additionally noted. The data indicate significant increases in absolute values of LV dimensions, aortic root size and left atrium (p<0.001) in preadolescent professional footballers compared with the values expected for age-matched controls, whereas there are no differences in absolute values of ventricular septal and posterior wall thickness, LV wall thickness and LVM (p>0.05). Upon body-size adjustments, significant increases were observed in all echocardiographic parameters (p<0.001). Our data indicate an early cardiac remodeling, already apparent in pre-adolescence, even after a short period of training. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
