概括
全身振动 (WBV) 主要激活骨髓调节反射 (BMR). 然而,皮肤冷却将其转移到强力振动反射 (TVR),这表明WBV运动期间肌肉的敏感性发生了变化.
科学领域:
- 神经肌肉生理学 神经肌肉生理学
- 运动科学 运动科学
- 振动疗法是一种振动疗法.
背景情况:
- 全身振动 (WBV) 已被认为具有神经肌肉益处,但其潜在的反射机制尚未完全理解.
- 根据振动幅度和肌肉活动,WBV会引起不同的反射:具有低幅度/自愿收缩的强力振动反射 (TVR),具有高幅度/静止的骨髓调节反射 (BMR).
- 受到同情输入影响的肌肉敏感度可能会随着短暂的皮肤冷却而增加.
研究的目的:
- 为了研究WBV在静静地站立时所发生的反射机制.
- 为了确定皮肤冷却如何调节这些WBV诱导的反射.
主要方法:
- 30名健康成年人接受了索莱斯肌肉反射延迟的评估.
- 强力振动反射 (TVR) 是通过阿基里斯肌振动来诱导的.
- 骨髓调节反射 (BMR) 是由WBV诱导的,两者都是在冷压试验 (CPT) 中测量.
主要成果:
- 单体TVR延迟时间为36.2 ± 5.1毫秒,单体BMR延迟时间为40.4 ± 5.0毫秒.
- 在CPT期间,阿基里斯肌振动 (TVR) 延迟没有显著变化 (p=0.319).
- 在CPT期间,WBV诱导的反射延迟显著减少 (36.0 ± 6.1 ms,p<0.0001),与TVR延迟相匹配.
结论:
- 在静静地站立时,WBV通常会激活BMR.
- 皮肤冷却会导致转变,在WBV期间TVR占主导地位,这可能是由于肌肉敏感度增加.
- 这些发现为优化WBV练习协议提供了关键的见解.

Somatic Spinal Reflexes
1.5K
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...

Thermosensation
30.2K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Thermoregulation
732
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Reflex Activity
1.4K
A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.

Methods of reducing fever
616
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Body Temperature
834
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
