BACKGROUND Abnormalities in the skeletal musculature underlie exercise intolerance in chronic heart failure (CHF). We investigated, whether in CHF selective resistance training without accompanying aerobic regime favourably affects muscle strength, muscle mass and improves exercise capacity. METHODS Ten patients with stable ischaemic CHF in NYHA class III(More)
OBJECTIVES The objective of this article is to review the literature regarding the effectiveness and safety of Nordic walking (NW) in therapeutic rehabilitation in patients of an advanced age. METHODS Randomized studies comparing NW with different patterns of long-lasting physical rehabilitation in older adults (average age 65 years) were selected for the(More)
Regular exercise plays an important preventive and therapeutic role in heart and vascular diseases, and beneficially affects brain function. In blood, the effects of exercise appear to be very complex and could include protection of vascular endothelial cells via neurotrophic factors and decreased oxidative stress. The purpose of this study was to identify(More)
BACKGROUND Single dose of N-methyl-N-nitrosourea (MNU) was shown to induce malignant tumours in susceptible rat strains. However, such tumours are not well-characterized. MATERIAL AND METHODS We characterized MNU-induced tumours in Sprague-Dawley rats using ultrasonographic, radiographic and immunohistochemical (IHC) methods. RESULTS In 27 rats, 41(More)
INTRODUCTION Secondary lymphedema affects approximately 40% of women treated for breast cancer and is recognized as a major problem associated with the therapy of malignant tumors.

BACKGROUND Heart failure (HF) is a systemic disease which affects mainly older adults. The main symptom of HF is exercise intolerance which in the course of disease can cause limitations in independent functioning. So far no study on the impact of HF on physical fitness in men, regardless of disease severity, has been reported. AIM To evaluate physical(More)
BACKGROUND Breast cancer treatment may be a cause of postural disorders. OBJECTIVE Assessment of the effects of various forms of physical activity on body posture in the sagittal plane in women post breast cancer treatment. STUDY GROUP Sixty women who had received breast cancer treatment. The study group was intentionally divided into three groups of 20(More)
The aim of the work was to determine the activity of trunk muscles in the sagittal plane in relation to body posture type in women treated for breast cancer. Fifty women having undergone treatment for breast cancer, with an average age of 61, participated in the study. All patients were studied by application of the photogrammetric method in order to(More)
QUESTION Does the distance covered during a 6-minute walk test predict risk of death or hospitalisation for cardiovascular reasons in men with stable heart failure over three years of follow-up? DESIGN Prospective observational study. PARTICIPANTS 243 men with stable systolic heart failure, with a mean age of 60 yr (SD 11) and left ventricular ejection(More)
The subject of this paper is to analyze the impact of radiotherapy and anthracyclines on the cardiovascular system, based on a survey of contemporary literature. Currently, high efficiency of anticancer therapies has increased the rate of survival in patients treated for cancer. It should be emphasized, however, that these treatments damage not only the(More)
