An echocardiographic evaluation of 77 members of a championship childhood swim team showed dimensional variations from normal in most athletes. Cardiac walls were thicker than the 95th percentile of normal: right ventricular anterior wall exceeded the 95th percentile in 100%, interventricular septum in 83% and left ventricular posterior wall in 91%. The left ventricular and left atrial cavities in diastole had mean values at the 50th percentile of normal but showed considerable scatter. The left ventricular cavity in systole had a mean value less than the 5th percentile of normal and also showed wide scatter. The aortic root and the aortic intercusp dimension exceeded the 95th percentile of normal in most subjects, 74% and 77%, respectively. No correlation existed between the coach's estimate of championship ability and echocardiographic wall or chamber sizes. Children who participate extensively in athletic training programs such as swimming may have echocardiograms which are q...

Left ventricular structure and function by echocardiography in childhood swimmers1994 •
The purpose of this study was to evaluate the results of a swim-test which we repeatedly used for the assessment of the fitness level in Hungarian male junior water-polo players by relating the results to the players’ echocardiographic parameters. It is a point of interest if a relationship between the results of the swim-test and cardiac function could exist. 26 male junior elite and 11 Olympic champion water-polo players participated in the swim-tests and the echocardiographic measurements. 25 healthy men served as a non-athletic comparison group. The swim test included the time result of a 30 m maximal intensity swim (Tmax), the mean time of a 6x30 m interval swim (Tmean), the number of heart beats during the 4 minutes of recovery (P4) and the difference between the heart beats during the first and the second half min. of recovery (Delta). Morphological and functional parameters of the heart were measured by echocardiography. The observed variables were related to body size by in...

Training-induced right ventricular remodelling in pre-adolescent endurance athletes: The athlete's heart in children2017 •
Little is known about the adaptation of the right ventricle (RV) to endurance exercise in children. The aim of this study was to assess the effects of 5months of intensive training on RV morphology and function in preadolescent endurance athletes. Ninety-four children were evaluated in this study. Fifty-seven male competitive swimmers (aged 10.8±0.2years) were evaluated before (baseline) and after 5months of the training (peak-training), and compared to 37 age- and sex-matched non-athlete children evaluated at baseline and after 5months of natural growth. All subjects were asymptomatic, with negative family history for cardiomyopathies. At baseline no differences were found between athletes and controls for indexed RV outflow tract (RVOT) (18.5±2.7 vs. 16.8±5.0mm/m(2), p=0.18) and RV basal end-diastolic diameter (EDD) (24.9±4.1 vs. 23.6±3.0mm/m(2), p=0.15). After 5months, indexed RVOT and RV basal EDD significantly increased in athletes (20.2±2.9mm/m(2) and 25.4±3.3mm/m(2), p<0.0...

Evaluation of left ventricular remodelling in young Afro-Caribbean athletesBackground Cardiac adaptation to intense physical training is determined by many factors including age, gender, body size, load training and ethnicity. Despite the wide availability of ECG analysis, with a higher presence of abnormalities in different races, echocardiographic studies on young Afro-Caribean (AA) and Caucasian athletes (CA) are lacking in literature. We aimed to assess the effect in the secondary LV remodelling of load training in young AA players compared to matched CA players. Method Seventy-seven AA and 53 CA matched soccer players (mean age 17.35 ± 0.50 and 18.25 ± 0.77 y) were enrolled. They were evaluated with echocardiography. A subgroup of 30 AA and 27 CA were followed up for a period of 4 years. The myocardial contractile function was evaluated by speckle-tracking echocardiographic global longitudinal strain (GLS). Results No significant differences were found in weight and height and in blood pressure response to maximal ergometer test in either group. In AA...

Left Ventricular Morphology in Different Periods of the Training Season in Elite Young Swimmers2015 •
Training adaptation of the left ventricle (LV) and it's reversibility following the cessation of training in adults is well known and also studied in children. In the present study we describe the changes in the LV morphology in association with the training season during a 1.5 year follow up period. 15 elite adolescent swimmers, seven girls and 8 boys with 6 years of swimming history and 20 hours per week training were observed. Their data were compared with 15 age and gender matched non-athletes. LV adaptation was measured with 2D-echocardiography at the baseline pre-season and every 3 months, according to the macro cyclic periods of training. Non-athletes were observed at the first and fifth stage of the study. Remarkable LV morphological adaptation has been detected in the swimmers. The greatest LV muscle mass (LVMM: 228±46g) and smallest end-diastolic diameter (LVIDd:44.9±3.4mm) were observed at the end of the second general endurance preparation period (GEP2), but the LVMM...

Comparison of cardiac structural, functional indices of male elite swimmers and triathletes with non- athleteshe purpose of this study was to investigate structural and functional cardiac indices in elite male swimmers and traithletes versus non-athletes. 20 elite male athletes (10 swimmers and 10 traithletes) and 10 healthy non-athletes volunteers participated in this study. Structural and functional cardiac indices measured by two dimensional, M mode and Doppler echocardiography. Data were analyzed by ANOVA, post-hoc Tukey and Pearson´ correlation coefficient at significance level 0.05. M-mode and two-dimensional measurements of the right and left ventricular cavity and wall were obtained in elite orienteers and sedentary males. For the right ventricle and wall, multiple cross-sections were used and measurements were obtained from the right ventricular inflow and outflow tract. The results indicated that LVDd was significantly greater in the thriathletes compared with the non-athletes (P<0.05). In addition, PW was significantly greater in thriathletes compared with the non-athletes (P&...

Differences in Heart Rate, Left Ventricular Wall Mass and Thickness, Diastolic Function, and Cardiac Output Index between Adolescent Athlete and Non-athlete AdolescentsBACKGROUND: Changes in cardiac function and structure in adolescent athletes increase the population’s risk for sudden death. No studies in Bali, Indonesia, have examined changes in cardiac function and structure in adolescent athletes compared to non-athlete. AIM: The objective of the study was to evaluate the cardiac function and anatomical structure of adolescent athletes. METHODS: This study was a cross-sectional study of male adolescents aged 15–18 years at the high school of Denpasar, Badung, Gianyar, and Tabanan from September 2019 to November 2020, using consecutive sampling. Mann–Whitney U-test was used to assess differences in heart rate, mass and left ventricular (LV) wall thickness, and diastolic function, while independent t-test was used to assess mean differences in the cardiac output index. RESULTS: A total of 88 subjects participated in this study. Heart rate in adolescent athletes was found to be slower than in non-athlete, with a median of 63.5 (range 46–107) beat...
