This study was designed to examine whether concurrent sprint interval and strength training (CT) would result in compromised strength development when compared to strength training (ST) alone. In addition, maximal oxygen consumption (VO2max) and time to exhaustion (TTE) were measured to determine if sprint interval training (SIT) would augment aerobic(More)
We have previously shown that the inhibition of myocardial nitric oxide (NO) and peroxynitrite-matrix metalloproteinase (MMP) signaling by early preconditioning (PC) is involved in its cardioprotective effect. Therefore, in the present study, we investigated the role of NO and peroxynitrite-MMP signaling in the development of late PC. PC was performed by(More)
KEY POINTS Silent mating type information regulation 2 homologue 1 (SIRT1) activity and content increased significantly in overload-induced hypertrophy. SIRT1-mediated signalling through Akt, the endothelial nitric oxide synthase mediated pathway, regulates anabolic process in the hypertrophy of skeletal muscle. The regulation of catabolic signalling via(More)
A decade ago, stem or progenitor cells held the promise of tissue regeneration in human myocardium, with the expectation that these therapies could rescue ischemic myocyte damage, enhance vascular density and rebuild injured myocardium. The accumulated evidence in 2014 indicates, however, that the therapeutic success of these cells is modest and the tissue(More)
BACKGROUND The aim of our study was to explore the effect of high-cholesterol diet and preconditioning on cardiac gene expression patterns in mouse hearts, focusing on genes involved in nitric oxide (NO) and free radical signaling and the mevalonate pathway. MATERIAL/METHODS Mice were fed 2% high-cholesterol or normal diet for 8 weeks. Hearts isolated(More)
Organic nitrates play an important role in the therapy of ischemic heart disease; however, their clinical application is limited by the development of vascular nitrate tolerance. We have previously shown attenuation of the cardioprotective effect of preconditioning in vascular nitrate tolerance. Here, we studied whether the development of vascular nitrate(More)
Metabolic and neurological responses to 4 bouts of lower-body or upper-body resistance exercise preceded by cycle ergometry or rest were assessed. Nine resistance-trained men (26.7 ± 6.6 years) underwent bouts of (a) cycle ergometry then bench press, (b) bench press only, (c) cycle ergometry then back squat, and (d) back squat only. Cycle ergometry was(More)
There are opposite views in the available literature: Whether physical exercise has a protective effect or not on the onset of inflammatory bowel disease (IBD). Therefore, we investigated the effects of recreational physical exercise before the induction of colitis. After 6 weeks of voluntary physical activity (running wheel), male Wistar rats were treated(More)
OBJECTIVES This study sought to determine the time dependency of the endothelium-dependent and -independent vascular responses after percutaneous coronary intervention (PCI) with drug-eluting (DEB) or plain balloons, bare-metal (BMS), and drug-eluting (DES) stents, or controls. BACKGROUND Long-term endothelial dysfunction after DES implantation is(More)
The incidence of myopathy increases dramatically in statin users who also exercise, likely limiting the positive impact of this lifesaving medication. New evidence also indicates that statin use can directly compromise aerobic exercise capacity; however, we are just beginning to understand the interactions of statins with exercise training and adaptations.(More)
