概括
无论是高强度,短持续时间还是低强度,长持续时间的静态拉伸都没有显著改善相反的运动范围或性能. 这些静态拉伸方案可能无法有效地促进受过训练的个体的交叉效应.
科学领域:
- 运动科学 运动科学 运动科学
- 生物力学 生物力学
- 运动生理学 运动生理学
背景情况:
- 急性静态拉伸 (SS) 可以增加对侧运动范围 (ROM),而不会影响力,功率或肌肉激活.
- 有限的研究存在于高强度,短期 (HISD) SS与低强度,长期 (LILD) SS对抵押品绩效的影响的比较.
研究的目的:
- 调查主导腿部腿筋的HISD和LILDSS对对侧肢表现的影响.
- 为了比较不同静态拉伸协议对ROM,力和肌肉激活的影响.
主要方法:
- 16名受过训练的参与者接受了三个干预措施:HISD SS (6x10s最大),LILD SS (6x30s初始) 和对照条件.
- 测量包括主导和非主导四肢ROM,最大自发同度收缩 (MVIC) 力量,肌肉激活的电肌图 (EMG),单边反运动跳跃 (CMJ) 和跌落跳跃 (DJ) 高度.
主要成果:
- 对于HISD或LILD SS.来说,没有观察到对手ROM或性能的显著增加.
- 在HISD条件下,伸展腿的ROM显著增加 (4.2%).
- 无论是HISD还是LILD条件都导致了强度,瞬间强度和EMG的严重损害,表明了潜在的负面急性影响.
结论:

Skeletal Muscle Relaxants: Adverse Effects
1.2K
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.

Muscle Stimulation Frequency
4.7K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

Isotonic and Isometric Muscle Contractions
28.7K
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.

Muscles of the Leg that Move the Foot and Toes
5.1K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Alterations in Muscle Tone ll
27
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
