背景情况:
- 腿筋受伤在高速跑步运动中很常见,运动后肌肉硬被认为是潜在的危险因素.
- 以前,缺乏用于监测运动后肌肉硬的时间过程的客观测量工具.
- 剪波弹性图 (SWE) 为评估组织硬性提供了一个客观的方法.
研究的目的:
- 确定和比较使用SWE的腿筋肌肉局部被动性的时间过程.
- 为了比较这个客观的硬度测量与主观的感知腿筋紧张的消耗性炼后.
主要方法:
- 24名受试者进行了倾斜腿曲运动,直到疲.
- 在多个时间点使用SWE量化了被动腿筋肌肉硬度 (基线,0,24,48,72,96小时后运动).
- 在同一时间点使用数值评分尺度来评估感知到的腿筋紧张.
主要成果:
- 随着时间的推移,在半膜体和双腿长头肌中没有观察到被动度的显著变化.
- 半肌的剪切模量显著增加,在48小时后达到峰值 (+9.7%),随后下降.

Isotonic and Isometric Muscle Contractions
4.2K
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.

Relaxation of Skeletal Muscles
3.8K
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....

Muscle Stimulation Frequency
2.6K
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.

Exercise and Muscle Performance
1.6K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
