BACKGROUND: It is well established that muscle strength and exercise capacity are impaired in adults with cystic fibrosis (CF). Numerous factors have been implicated in this process including nutritional factors, disuse, and corticosteroid use. It is also known that serum testosterone levels are frequently low in adolescent male patients with ...

The constant-RPE tracking model monitors progress over the course of exercise training. During aerobic exercise, prior work using this model has demonstrated similar relative intensities pre- and posttraining, while the absolute workload increases posttraining. However, the prediction equation associated with these changes has not been examined during resistance training. 22 ...

Strength training with low loads in combination with vascular occlusion has been proposed as an alternative to heavy resistance exercise in the rehabilitation setting, especially when high forces acting upon the musculo-skeletal system are contraindicated. Several studies on low-to-moderate intensity resistance exercise combined with cuff occlusion have demonstrated increases in ...

Although exercise speed is an acute variable to prescribe abdominal strengthening programs, current literature lacks studies analyzing the influence of speed on muscular activation in abdominal exercises. The aim of this work was to determine the influence of trunk curl-up speed on the amplitude of muscular activation and the way ...
Alcaraz Pedro E - - 2008
Circuit training effectively reduces the time devoted to strength training while allowing an adequate training volume to be achieved. Nonetheless, circuit training has traditionally been performed using relatively low loads for a relatively high number of repetitions, which is not conducive to maximal muscle size and strength gain. This investigation ...

Pediatric heart transplant recipients have been shown to have reduced exercise performance. Studies of adult heart transplant recipients demonstrate improved endurance from regular aerobic exercise; however, this strategy has not been studied in children. We hypothesized that regular aerobic/strength training would improve exercise performance in children post-heart transplant. After an ...

Levodopa (LD) application improves motor symptoms and reduces cortisol levels in patients with Parkinson's disease (PD). Endurance exercise enhances cortisol release in proportion to the intensity of the effort and thus may counteract the LD associated cortisol decrease. We measured levels of cortisol and LD over an 1-h long interval ...

Adaptive effects caused by mechanical acoustic vibrations on the neuromuscular system are widely described. These vibrations applied to the muscle belly cause the "vibration tonic reflex" characterized by an improvement in power contraction of the stimulated muscle. Mechanical acoustic vibrations of moderate strength placed on limited body areas produce a ...

Proponents of chain training suggest that using chains hung from the ends of barbells rather than using conventional barbells alone enhances strength, power, and neuromuscular adaptations. The purpose of this study was to determine whether a conventional barbell with chains compared to a conventional barbell without chains would affect the ...

Disease-related atrophy of the tongue muscles can lead to diminished lingual strength and swallowing difficulties. The devastating physical and social consequences resulting from this condition of oropharyngeal dysphagia have prompted investigators to study the effects of tongue exercise in improving lingual strength. We developed the Madison Oral Strengthening Therapeutic (MOST) ...
