UNLABELLED BACKGROUND Quercetin is a natural polyphenolic compound currently under study for its ergogenic capacity to improve mitochondrial biogenesis. Sedentary mice have exhibited increased endurance performance, but results are contradictory in human models. METHODS We examined the effects of six weeks of endurance training and quercetin supplementation on markers of endurance performa...

exercise training has been shown to decrease chronic low- grade systemic inflammation in high- fat diet induced obesity. however, the mechanisms mediating its beneficial effects are not fully understood. therefore, the aim of this study was to investigate the effects of a 12- week endurance training on il-6, il-10 and nesfatin -1 in obese male rats. sixteen male wistar rats (2 months old) were ...

To compare training programs for women with trapezius myalgia regarding physical performance and pain, 102 women were randomized to strength, endurance, co-ordination and non-training groups. Before and after the intervention, static strength and dynamic muscular endurance in shoulder muscles were measured on a Cybex II dynamometer. Muscle activity in shoulder muscles was monitored via surface ...

Purpose. the association between anthropometric and training characteristics on an athlete’s performance has been investigated in swimmers, cyclists and runners, but not in inline skaters. the aim of this study was to investigate the relationship between anthropometry, pre race preparation and equipment in the finishers of the longest inline race in Europe, the ‘Inline One eleven’ over 111 km i...

Arterial stiffness is higher in strength-trained humans and lower in endurance-trained humans. However, the mechanisms underlying these different adaptations are unclear. Vascular endothelium-derived factors, such as endothelin-1 (ET-1) and nitric oxide (NO), play an important role in the regulation of vascular tonus. We hypothesized that endogenous ET-1 and NO participate in the adaptation of ...

BACKGROUND It is well established that prolonged, exhaustive endurance exercise is capable of inducing skeletal muscle damage and temporary impairment of muscle function. Although skeletal muscle has a remarkable capacity for repair and adaptation, this may be limited, ultimately resulting in an accumulation of chronic skeletal muscle pathology. Case studies have alluded to an association betwe...

STUDY OBJECTIVES The purpose of this study was to compare the effects of endurance training only to endurance plus strength (combined) training in a randomized trial of patients with COPD. METHODS Twenty-four patients completed the study: 11 patients in the combined training group (FEV(1) 45 +/- 5% predicted), and 13 patients in the endurance training group (FEV(1) 40 +/- 4% predicted) [mean ...

We studied the effect of an alteration from regular endurance to speed endurance training on muscle oxidative capacity, capillarization, as well as energy expenditure during submaximal exercise and its relationship to mitochondrial uncoupling protein 3 (UCP3) in humans. Seventeen endurance-trained runners were assigned to either a speed endurance training (SET; n = 9) or a control (Con; n = 8) ...
