Background: Although breathlessness is common in chronic heart failure (CHF), the role of inspiratory muscle dysfunction remains unclear. We hypothesised that inspiratory muscle endurance, expressed as a function of endurance time (Tlim) adjusted for inspiratory muscle load and inspiratory muscle capacity, would be reduced in CHF. Methods: Endurance was measured in 10 healthy controls and 10 pa...

OBJECTIVE Muscle resistance training is often combined with aerobic endurance training during rehabilitation of patients with coronary artery disease. However, the clinical effects of additional lower-extremity low-intensity muscle resistance training during early rehabilitation (within the first month after coronary revascularization) in patients with coronary artery disease remain unclear. ...

the aim of this study was to determine the short-term (1 session) and long-term (36 sessions) effects of various exercise training (endurance, sprint, and combined) on plasmatic indexes of muscle damages (lactate dehydrogenase, creatine kinase, and malondialdehyde). for this purpose, 40 young rats (3 months old) were randomly divided into four groups including control, endurance, sprint, and co...

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) ...

BACKGROUND Grip strength is widely used for estimating whole body strength but there is a lack of information relating to grip endurance. Comparison between endurance of different muscle groups has received little attention. The main aim of the present study was to determine the endurance characteristics of hand grip and quadriceps muscles in healthy young adults and then to examine the associa...

Pyruvate dehydrogenase (PDH) plays an important role in regulating carbohydrate metabolism in skeletal muscle. PDH is activated by PDH phosphatase (PDP) and deactivated by PDH kinase (PDK). Obesity has a large negative impact on skeletal muscle carbohydrate metabolism, whereas endurance training has been shown to improve regulatory control of skeletal muscle carbohydrate metabolism, more so whe...

UNLABELLED Previous studies in adults have demonstrated power athletes as having greater muscle force and muscle activation than nonathletes. Findings on endurance athletes are scarce and inconsistent. No comparable data on child athletes exist. PURPOSE This study compared peak torque (Tq), peak rate of torque development (RTD), and rate of muscle activation (EMG rise, Q30), in isometric knee...

BACKGROUND The complications associated with type 2 Diabetes Mellitus (DM) may cause functional impairment in older people. Recently it has been proved that motor dysfunction in the form of skeletal muscle dysfunction does occur in type II DM. However very few studies have assessed the upper limb skeletal muscle dysfunction. OBJECTIVES The study was aimed to assess the hand grip strength, end...

BACKGROUND Children with SLE are known to have higher fat mass compared to their peers but there are no published data regarding exercise capacity as measured by cardiovascular endurance and muscle strength. In our pilot study of ten children with SLE, we sought to examine body composition, cardiovascular endurance, and isometric muscle strength. FINDINGS Ten pediatric SLE patients were studi...
