Based on the data collected by KNOLL Hungary Ltd. in Hungary in 1999, 37% of the adult population is overweight while 23% is obese. Inappropriate diet containing excess calories and physical inactivity are responsible for these statistical values. In their former studies, the authors investigated the effects of different stages of obesity on the cardiovascular system, and have verified that even moderate obesity elicits pathological geometric and functional changes in the heart. In the present study, effect of a half-year-long life-style modification program on the morphologic and functional characteristics of the heart was investigated in twenty-one obese women. Life-style modification contained a diet with reduced energy uptake (1000-1300 Cal/day) and a regular physical training of minimum 3-4 hours weekly. By the end of the sixth month the weight loss was 5.1 kg (5.9%) on an average. There was a marked reduction in cardiac dimensions measured by echocardiography, with a very slight, non-significant decrease in left ventricular internal diameter, and a marked, significant reduction in the left ventricular wall thickness. Decrease of the left ventricular muscle mass exceeded the decrease of body weight. A marked elevation was found in the E/A quotient that reflected a definite improvement in diastolic function. Results indicate that physical training programs have a favourable effect on the echocardiographic parameters, therefore the process is reversible even without a pharmacological intervention.

OBJECTIVE:The aim of the present study was to compare cardiac hypertrophy and diastolic function in extremely obese male patients and physically active adult male subjects of similar age (means 43.0-43.4 y). DESIGN: Data of male patients referred to our hospital ward in order to reduce their body weight (BW) were compared with those of physically active and nonactive healthy males. SUBJECTS: The groups contained 21-24 male subjects, very active and moderately active subjects taking part in regular competitive or leisure time physical activity were in the two athletic groups, severely overweight patients constituted the obese group and healthy persons served as controls. MEASUREMENTS: Two-dimensionally guided M-mode and Doppler recordings. RESULTS: In comparison with the controls, obese patients had larger left atrial systolic and left ventricular (LV) diastolic internal diameters, LV diastolic wall thickness and muscle mass. Of the body size-related indices, only the left atrial systolic diameter index was significantly higher. LV systolic and diastolic functions were impaired as indicated by a decreased ejection fraction (EF), higher heart rate (HR), decreased E/A quotient and increased isovolumetric relaxation time. In the physically very active subjects, a thicker LV diastolic wall was seen without LV dilatation. Body size-related wall thickness and muscle mass were significantly higher than in the controls. EF and HR did not differ from those of the controls. CONCLUSION: The most useful help to distinguish between physiological and pathological left ventricular hypertrophy can be to investigate diastolic functions. The most salient difference appeared in diastolic function, because E/A quotient was higher in the very active subjects than in the controls and it was the lowest in the obese persons.

The Hungarian National Institute for Sports Medicine (NISM) was founded in 1952 to provide medical coverage for national teams, screening and periodic health evaluation (PHE) for all Hungarian athletes. The system of ‘all in one and ASAP’ evolved by now to a specific state-funded healthcare provider with complex sports medical and sport-related services available for athletes. The NISM created a countrywide network to make health clearance available for all athletes close to their place of residency. This centralised system guarantees the uniformity and financial independence of the network, as it is directly financed by the government and free for every competitive athlete. Thus, it leaves no chance for conflict of interest in evaluating athletes’ eligibility. In 2013, NISM established an online registry for preparticipation screening and PHE. This made the registry available for sports physicians and certain data for both sports physicians and athletes themselves. Furthermore, NISM created a nationwide, centrally coordinated, out of turn care with central coordination for elite athletes nationwide. Outpatient and inpatient clinics of NISM provide sports-specific care. Most of the minimally invasive techniques used at the Department of Sports Surgery are applied only here in the country. The medical staff of NISM has special experience in Sports Medicine and sport-related conditions. All tasks are managed within the same system, within institutional frames by professionals at Sports Medicine, which guarantees institutional expertise, competence and responsibility. Our aim is to introduce the complex system, the services and the recent achievements of the Hungarian NISM.
