Active Stretching
Active stretching eliminates force and its adverse effects from stretching procedures or it can also be defined as a stretch that requires you to retain a posture without any help other than the strength of your agonist's muscles is known as an active stretch. Active stretching stimulates and prepares muscles for use during exercise. Active stretches not only stretch the muscles and tissues, but prepares the muscles for the action by activating and warming them up or a stretch that requires you to retain a posture without any help other than the strength of your agonist's muscles is known as an active stretch.. Before describing the principles on which active stretching is based, the terms agonist and antagonist must be clarified. Agonist refers to the actively contracting muscle or muscles while their opposing muscles are termed antagonists. The neuromechanisms conceptualized by Sir Charles Sherrington (1857 - 1956), “the philosopher of the nervous system”, as applied to act ...

Agonist (muscle)
Anatomical terminology is used to uniquely describe aspects of skeletal muscle, cardiac muscle, and smooth muscle such as their actions, structure, size, and location. Types There are three types of muscle tissue in the body: skeletal, smooth, and cardiac. Skeletal muscle Skeletal muscle, or "voluntary muscle", is a striated muscle tissue that primarily joins to bone with tendons. Skeletal muscle enables movement of bones, and maintains posture. The widest part of a muscle that pulls on the tendons is known as the belly. Muscle slip A muscle slip is a slip of muscle that can either be an anatomical variant, or a branching of a muscle as in rib connections of the serratus anterior muscle. Smooth muscle Smooth muscle is involuntary and found in parts of the body where it conveys action without conscious intent. The majority of this type of muscle tissue is found in the digestive and urinary systems where it acts by propelling forward food, chyme, and feces in the former and u ...

Sir Charles Sherrington
Sir Charles Scott Sherrington (27 November 1857 – 4 March 1952) was an eminent English neurophysiologist. His experimental research established many aspects of contemporary neuroscience, including the concept of the spinal reflex as a system involving connected neurons (the "neuron doctrine"), and the ways in which signal transmission between neurons can be potentiated or depotentiated. Sherrington himself coined the word "synapse" to define the connection between two neurons. His book ''The Integrative Action of the Nervous System'' (1906) is a synthesis of this work, in recognition of which he was awarded the Nobel Prize in Physiology or Medicine in 1932 (along with Edgar Adrian). In addition to his work in physiology, Sherrington did research in histology, bacteriology, and pathology. He was president of the Royal Society in the early 1920s. Biography Early years and education Official biographies claim Charles Scott Sherrington was born in Islington, London, England, o ...

Muscle Spindles
Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers. This information can be processed by the brain as proprioception. The responses of muscle spindles to changes in length also play an important role in regulating the contraction of muscles, for example, by activating motor neurons via the stretch reflex to resist muscle stretch. The muscle spindle has both sensory and motor components. * Sensory information conveyed by primary type Ia sensory fibers which spiral around muscle fibres within the spindle, and secondary type II sensory fibers * Activation of muscle fibres within the spindle by up to a dozen gamma motor neurons and to a lesser extent by one or two beta motor neurons Structure Muscle spindles are found within the belly of a skeletal muscle. Muscle spindles are fusiform (spindle-shaped), and the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stretching
Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately flexed or stretched in order to improve the muscle's felt elasticity and achieve comfortable muscle tone. The result is a feeling of increased muscle control, flexibility, and range of motion. Stretching is also used therapeutically to alleviate cramps and to improve function in daily activities by increasing range of motion. In its most basic form, stretching is a natural and instinctive activity; it is performed by humans and many other animals. It can be accompanied by yawning. Stretching often occurs instinctively after waking from sleep, after long periods of inactivity, or after exiting confined spaces and areas. Not only vertebrates (mammals and birds), but also spiders were found to exhibit stretching in 2021. Increasing flexibility through stretching is one of the basic tenets of physical fitness. It is common for athletes to stretch before (for warming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
