Background • Vitamin K1 and K2 are not typically common in a Western diet because they are found in a variety of fermented foods. Vitamin K2 in particular has been demonstrated to restore mitochondrial function and has a key role in production of mitochondrial adenosine triphosphate. Thus, it is reasonable to speculate that dietary supplementation with vitamin K2 could increase the function of muscle with high mitochondrial content (ie, skeletal and cardiac muscle). Objective • The purpose of this study was to determine if 8 wk of dietary supplementation with Vitamin K2 could alter cardiovascular responses to a graded cycle ergometer test...

BACKGROUND: The association between chronic kidney disease (CKD) and obesity can decrease the patients' cardiopulmonary capacity, physical functioning and quality of life. The search for effective and practical alternative methods of exercise to engage patients in training programs is of great importance. Therefore, we aimed to compare the effects of home-based versus center-based aerobic exercise on the cardiopulmonary and functional capacities, quality of life and quality of sleep of overweight non-dialysis-dependent patients with CKD (NDD-CKD)...

Omentin-1, also known as intelectin-1, is a recently identified novel adipocytokine of 313 amino acids, which is expressed in visceral (omental and epicardial) fat as well as mesothelial cells, vascular cells, airway goblet cells, small intestine, colon, ovary, and plasma. The level of omentin-1 expression in (pre)adipocytes is decreased by glucose/insulin and stimulated by fibroblast growth factor-21 and dexamethasone. Several lines of experimental evidence have shown that omentin-1 plays crucial roles in the maintenance of body metabolism and insulin sensitivity, and has anti-inflammatory, anti-atherosclerotic, and cardiovascular protective effects via AMP-activated protein kinase/Akt/nuclear factor-κB/mitogen-activated protein kinase (ERK, JNK, and p38) signaling...

BACKGROUND: High intensity interval training (HIIT) increases maximal oxygen uptake similar to aerobic exercise. However, changes in body composition are equivocal in response to HIIT. AIM: We examined changes in body composition and dietary restraint in response to 20 sessions of HIIT varying in structure. METHODS: Thirty nine active men and women (age and VO2max = 22.5 ± 4.4 yr and 40.1 ± 5.6 mL/kg/min) were randomized to one of three periodized HIIT regimes performed on a cycle ergometer...

Endothelin (ET)-1-mediated vasoconstrictor tone is elevated in overweight and obese adults, contributing to vasomotor dysfunction and increased cardiovascular disease risk. While the effects of habitual aerobic exercise on endothelium-dependent vasodilation in overweight/obese adults has been studied, little is known regarding ET-1 vasoconstriction. Accordingly, the aims of the present study were to determine: (1) if regular aerobic exercise training reduces ET-1-mediated vasoconstrictor tone in overweight and obese adults; and, if so (2) whether the reduction in ET-1 vasoconstriction contributes to exercise-induced improvement in endothelium-dependent vasodilation in this population...

There is substantial evidence of rising prevalence of overweight and obesity and its co-morbidities among children in western-high income developed countries. In the European Union, the prevalence of overweight and obesity is increasing fastest among Polish children. Yet, there is paucity of evidence on the relationship of behavioral factors with body weight status of children in Poland. This study examined the association of obesity with physical fitness, physical activity, sedentary behavior and diet among Polish children...

BACKGROUND: The overexpression of human epidermal growth factor receptor-2 (HER2) in breast cancer is a poor prognosis. Trastuzumab improves overall survival but is associated with cardiotoxicity, especially a decline in left ventricular ejection fraction (LVEF). In addition, chemotherapy and radiotherapy increase fatigue and pain, decrease physical capacity and health-related quality of life. To date, no study has evaluated the benefits of physical activity on the side effects of treatment in patients with HER2 positive breast cancer...

INTRODUCTION: From the previously published literature on the relationship between obesity and infertility, it is clear that male obesity negatively impacts semen quality. Accordingly, this study was conducted to determine whether regular exercise may improve semen quality in sedentary obese adults. MATERIAL AND METHODS: Ninety obese adults were randomly allocated to the intervention (n = 45) or control group (n = 45). Participants in the intervention group performed a 16-week aerobic training program in a treadmill, three sessions per week, consisting of a warm-up (10-15 minutes), 35-50 minutes treadmill exercise (increasing five minutes per four weeks) at a work intensity of 50-65% of peak heart rate (increasing a 5% per four weeks) and cooling-down (5-10 minutes)...
