- 为了确定腰部肌肉训练的最佳角度,并了解外围肌肉力量传递.
- 阐明PTE期间不同肌肉的调制策略和相互作用模式.
主要方法:
- 20名健康的年轻女性参与了这项研究.
- 使用MyotonPRO.测量了起器脊柱 (ES),腿筋 (半,大腿) 和腹肌 (中间和侧面的头) 的肌肉刚性.
- 在四个PTE角度进行测量:0° (水平),10°,20°和30°.
主要成果:
- 勃起脊柱 (ES) 的度随着PTE角度的增加而减少,而腿筋 (ST,BF) 的度最初增加,然后减少.
- 胃半关节 (MG,LG) 硬度表现出更复杂的模式:增加,然后减少,然后再次增加.
- 在ES度变化和ST,BF,MG和LG的度之间发现了显著的负相关性,表明了张力转移.
结论:
- 一个水平的PTE位置 (0°) 似乎可以最大限度地激活起器脊柱 (ES).

Relaxation of Skeletal Muscles
3.4K
The period of muscle contraction primarily influences the duration of stimulation at the neuromuscular junction (NMJ), the presence of free calcium ions in the sarcoplasm, and the availability of energy or ATP to support contractions.
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....

Classification of Skeletal Muscle Relaxants
2.5K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.

Skeletal Muscle Relaxants: Adverse Effects
401
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.
