概括
力量训练可以增强神经通路,特别是皮质 - 视网 - 脊髓,从而改善运动功能. 这项研究揭示了训练有素的运动员与未经训练的个人相比,神经刺激能力更强.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 运动生理学 运动生理学
背景情况:
- 神经适应力量训练可以改善运动通路的功能.
- 之前的研究集中在皮质脊柱管上,但最近的证据表明,皮质下网膜脊柱管可能是关键.
- 了解这些适应对于优化培训和康复至关重要.
研究的目的:
- 为了研究长期强力训练运动员的神经适应部位.
- 为了比较训练有素的运动员和未经训练的个人之间的皮质脊髓和视网脊髓管的功能.
- 为了确定视网脊柱管是否在力量训练适应中发挥主要作用.
主要方法:
- 15名力量训练运动员和18名未经训练的成年人的横截面比较.
- 神经生理学测试包括StartReact测试 (测量反应时间,扭矩和肌肉活动) 和跨磁刺激 (TMS) 以评估皮层脊髓和视网脊髓刺激性.
- 对双臂肌肉对视觉,视听和视觉惊线索的反应以及TMS诱导的运动唤起潜能 (MEP) 的分析.
主要成果:
- 未经训练的成年人从StartReact测试中获得了更大的好处,这表明了更高的视网脊髓增益.
- 力量训练的运动员在更高的TMS强度和更短的沉默期时表现出更大的MEP,这表明皮质脊髓刺激性得到了增强.

4.8K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

01:22Indirect Motor Pathways
3.0K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

01:22Isotonic and Isometric Muscle Contractions
6.7K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
