The production of neurotrophin-4 (NT-4) in rat skeletal muscle was found to depend on muscle activity. The amounts of NT-4 messenger RNA present decreased after blockade of neuromuscular transmission with alpha-bungarotoxin and increased during postnatal development and after electrical stimulation in a dose-dependent manner. NT-4 immunoreactivity was detected in slow, type I muscle fibers. Int...

neuromuscular disorders encompass a broad spectrum of disorders from the anterior horn cell to the muscle tissue itself. the given condition can be either genetic or acquired. these group of disorders are diagnostically challenging as many of them also pose other systemic findings. one example would the commonly seen mental retardation in duchenne muscular dystrophy. from the practical point of...

Background: Identifying lower extremity defects during high impact activity, such as landing, especially in young athletes who play team sports, could help to prevent non-contact lower extremity injuries. The Tuck Jump Assessment (TJA) is a screening instrument designed to recognize neuromuscular deficits related to Anterior Cruciate Ligament (ACL) injury. The current study investigated the pre...

The aim of this study was to evaluate the effects of integrative neuromuscular training (INT) during physical education (PE) class on selected measures of health- and skill-related fitness in children. Forty children from two 2nd grade PE classes were cluster randomized into either an INT group (n = 21) or a control (CON) group (n = 19). INT was performed 2×/wk during the first ~15 min of each ...

The first purpose of this study was to determine the effects of whole-body vibration (WBV) exercise during an isometric hand-grip exercise. The second purpose was to evaluate whether more than one vibratory focus would evoke an increase in the effects evoked by only one vibratory focus. The present study investigated whether WBV exposure during 10 repetitions of a handgrip dynamometer while sta...

The study evaluates the effect of soccer match induced fatigue on the neuromuscular performance. Prior to, during the break period between the 1st and 2nd part of the game and after the game, parameters of agility, explosive power of lower limbs, static and dynamic balance, speed of step initiation and the soccer kick were evaluated in a group of 10 soccer players. Reaction time in the agility ...

PURPOSE Electromechanical delay (EMD) and rate of force development (RFD) are determinants of explosive neuromuscular performance. We may expect a contrast in EMD and RFD between explosive power athletes, who have a demonstrable ability for explosive contractions, and untrained individuals. However, comparison and the neuromuscular mechanisms for any differences have not been studied. METHODS...

INTRODUCTION Approximately 4 to 7 percent of workers are exposed to potentially harmful levels of WBV in Canada, the United States, and some European countries [1]. Exposure to vibration is known to cause certain physiological responses. However, there is still a lack of understanding on how these responses tax the neuromuscular system. The objective was To investigate whether exposure to vibra...

The purpose of this study was to investigate the effects of short term resistance exercise on neuromuscular fatigue threshold (PWCFT), strength, functional performance, and body composition in older adults. Twenty-three participants (71.2 ± 6.0 yr) were randomly assigned to 6 weeks of resistance exercise (EXE) or control (CONT). A submaximal cycle ergometer test, physical working capacity at fa...
