The effect of endurance training on neuronal nitric oxide synthase (nNOS) content and distribution in muscle was investigated. Seven male subjects performed 6 wk of one-legged knee-extensor endurance training (protocol A). Muscle biopsies, obtained from vastus lateralis muscle in the untrained and the trained leg, were analyzed for nNOS protein and activity as well as immunohistochemical distri...

We tested the effect of a home-based respiratory muscle endurance training in patients with mild to moderate generalized myasthenia gravis (MG) on Besinger score, lung function and respiratory muscle endurance. Ten patients performed respiratory muscle endurance training in form of normocapnic hyperpnea training at 50-60% of their maximal voluntary ventilation over 4-6 weeks. MG score, lung fun...

The effect of concurrent strength (S) and endurance (E) training on adaptive changes in aerobic capacity, endurance performance, maximal muscle strength and muscle morphology is equivocal. Some data suggest an attenuated cardiovascular and musculoskeletal response to combined E and S training, while other data show unimpaired or even superior adaptation compared with either training regime alon...

Self-regulation consumes a form of strength or energy. The authors investigated aftereffects of self-regulation depletion on muscle-endurance performance in older adults. Participants (N = 61, mean age = 71) were randomized to a self-regulation-depletion or control group and completed 2 muscle-endurance performance tasks involving isometric handgrip squeezing that were separated by a cognitive-...

Th is study evaluated changes in shoulder muscle isometric endurance, deltoideus and trapezius muscle electromyographic activity (EMG) and stiff ness in patients with frozen shoulder syndrome (FSS) before and aft er manipulation under general anaesthesia (MUA). Eighteen FSS patients with mean age of 53±9 years participated. Isometric endurance of shoulder muscles was characterized by endurance ...

PURPOSE This is a pilot study to determine if endurance exercises for dorsiflexors will improve walking for people with foot drop secondary to MS, and if improvement in muscle endurance for persons with MS can be predicted based on the amount of central fatigue (CF) in the muscle. SUBJECTS Five individuals with foot drop secondary to MS and five age-matched controls. METHODS The interventio...

Exercise-induced muscle oxidative stress may be involved in the myopathy associated with chronic obstructive pulmonary disease (COPD). This study was designed to look at whether local exercise induces muscle oxidative stress and whether this may be associated with the reduced muscle endurance in COPD. Quadriceps endurance was measured in 12 patients with COPD (FEV1 = 0.96 [[plusmn]] 0.14 SEM) a...

the subjective of this study was to explore and compare the effects of whole body vibration (wbv) and conventional spinal stabilization exercises on persons with non-specific chronic low back pain (clbp). thirty patients with non-specific chronic low back pain randomly received 6 sessions of spinal stabilization therapy with and without whole body vibration over 2 weeks. the severity of pain, f...

BACKGROUND Respiratory muscle endurance training (hyperpnea training) has been shown to have beneficial effects in patients with COPD. STUDY OBJECTIVES The purpose of this study was to determine whether hyperpnea training, when added to an endurance exercise training program, would lead to additional benefits compared with endurance training alone in patients with COPD. SETTING AND PARTICIP...
