Motor unit plasticity : ウィキペディア英語版 | Motor unit plasticity The motor unit consists of a voluntary alpha motoneuron and all of the collective muscle fibers that it controls, known as the effector muscle. The alpha motoneuron communicates with acetylcholine receptors on the motor end plate of the effector muscle. Reception of acetylcholine neurotransmitters on the motor end plate causes contraction of that effector muscle. Motor unit plasticity is defined as the ability of motoneurons and their respective effector muscles to physically and functionally change as a result of activity, age, and other factors. Motor unit plasticity has implications for improved athletic performance and resistance to immobility as a result of age. Recent advanced training techniques and physical therapy techniques that focus on improving neural function in addition to muscular function show promising results to improving athletic performances and extending mobility for the elderly.〔Physical Activity: Strength Training for Older Adults. Center for Disease Control and Prevention. (2010).〕 ==Plasticity due to Resistance Training== Resistance training has been shown to dramatically increase performance of motor units of the larger muscle groups.〔Aagaard, P. (2003). Training-induced changes in neuronal function. Exercise and Sport Sciences Reviews. 31(2). 61-67.〕 Motor unit plasticity of the larger muscle groups is extremely important for athletes, especially those participating in high impact and fast pace sports such as track and field, martial arts, and American football. Training that focuses on improving muscle strength and neural function via resistance training, is currently incorporated into many professional and collegiate training regiments. Motor unit plasticity can be measured in many ways, the most important of which being neural firing frequency, EMG amplitude, muscle force output, pre-synaptic inhibition, and synchronization.
