Cardiac β-adrenoceptor density and β1- and β2-subtype distribution were examined in human left ventricular myocardium from transplant donors serving as controls and from patients with mitral valve stenosis, aortic valve stenosis, idiopathic dilated cardiomyopathy, and ischaemic cardiomyopathy respectively. The total β-adrenoceptor density was similar in(More)
Only few data are available concerning the biochemical and functional state of the \-adrenergic system in hypertrophied human myocardium. The present study was to investigate the myocardial \-adrenergic signal transduction system in hypertrophic obstructive cardiomyopathy (HOCM). Thin myocardial strips were prepared from surgically excised, septal(More)
The ryanodine-sensitive Ca2+ release channel (RyaCRC) of the sarcoplasmic reticulum plays a key role in the intracellular Ca2+ handling in cardiomyocytes. Altered expression of the RyaCRC has been supposed to contribute to abnormal cellular Ca2+ handling and to myocardial dysfunction in dilated and ischemic cardiomyopathy. In the present study the(More)
The goals of this study were to evaluate the basic morphological variables of contemporary elite ice hockey players, compare the parameters of players in the top Russian ice hockey league (KHL) with those of the top Czech ice hockey league (ELH), and to evaluate the parameters of players according to their position in the game.

The purpose of the study was to analyse the changes in muscle strength, power, and somatic parameters in elite volleyball players after a specific pre-season training programme aimed at improving jumping and strength performance and injury prevention. Twelve junior female volleyball players participated in an 8-week training programme. Anthropometric(More)
In the framework of completing the aim of the project supporting health, which is entitled “Intervention programme for optimal mobility and its influence on health” in June 1998 we carried out a physical diagnosis of University students of the 3rd age at the Faculty of Physical Culture. The test group finished the 2nd year with a specialisation “Journey to(More)
