When the receptor portion of the muscle spindle is stretched slowly, the number of impulses transmitted from both the primary & secondary endings increases virtually in proportion to the degree of stretch. (positivehealth.com)
Its function is manifested in the form of the muscle stretch reflex, which consists of static & dynamic reflexes. (positivehealth.com)
The dynamic stretch reflex is caused by the potent dynamic signal transmitted via the primary endings of the muscle spindles. (positivehealth.com)
With the dynamic stretch reflex over within a few a fraction of a second after the muscle has been stretched to its new length, a much weaker static reflex continues after for as long as the muscle is maintained at an excessive length. (positivehealth.com)

This kind of training typically involves at least 6 large muscle groups through which muscle contraction results in movement, such as lifting weights, squats, and push-ups. (pharmacytimes.com)
Typically a chordotonal organ has 60-100 or more sensory neurons embedded within an elastic strand, neurons that signal static joint position, direction and speed of movement 3-6 . (jove.com)

Extended periods of abnormal positioning, such as a constantly seated position or awkward violin positioning, can cause affected muscles to actually reset their normal length. (internationalmusician.org)

This type of training involves the static contraction of muscles, such as with the handgrip exercise. (pharmacytimes.com)
It is believed that conscious abdominal contraction (CAC) during exercise encourages greater periscapular activation through existing myofascial connections. (humankinetics.com)
To analyze the effect of CAC on periscapular muscle activity during push-up plus exercise on stable and unstable surfaces and to evaluate the correlation between electromyographic (EMG) activity of the serratus anterior (SA) and abdominal oblique muscles. (humankinetics.com)
Change in sEMG amplitude during isometric exercise may be related to muscles fatigue. (aaem.pl)

But a small number of large sensory fibres from the muscle spindles terminate directly on the anterior motor neurons. (positivehealth.com)
The receptor portion of the muscle spindle is located midway between its to ends where the intrafusal muscle fibres have no contractile element. (positivehealth.com)
This causes both the extrafusal & intrafusal muscle fibres to contract at the same time. (positivehealth.com)
Following a direct impact to the quadriceps, damage to the muscle fibres, connective tissue and small blood vessels of the quadriceps may occur. (physioadvisor.com.au)
Muscles give us mobility and for efficient locomotion, muscle fibres need to be at a suitable length. (exercisedaily.com)

Can the Use of Unstable Surfaces and Instruction for Conscious Abdominal Contraction Increase the EMG Activity of the Periscapular Muscles During the Dynamic Push-Up? (humankinetics.com)
You can help reduce or eliminate bladder leaks by ensuring that your pelvic floor has enough power and endurance to support you through all your activities, and that it's well coordinated with your deep abdominal muscle contractions (your Transverse abdominus ). (poise.com)

Proprioceptors consist of position (static) and movement (kinesthetic) receptors. (jove.com)

The muscle being contracted to perform a movement. (drillsandskills.com)
The muscle acting in opposition of an intended movement. (drillsandskills.com)
These symptoms include a noticeable lump or 'woody' feeling in the belly of the injured muscle, an increase in morning pain, pain with activity or night pain and a clinical history demonstrating an initial improvement in range of movement followed by a period of deterioration. (physioadvisor.com.au)
In the butt and thigh press, the outer thigh and hip muscle groups are in a static contraction, while the quadriceps in the front of the thigh and gluteals in the buttocks perform the movement that extends the leg at the hip and knee. (howstuffworks.com)

Static training involves taking a weight and holding it in a fixed position for several seconds. (bodybyfadi.com)

The current and more accurate term "electronic training devices" recognizes that while the products do incorporate a degree of electrical or "static" stimulation, the term "shock" is a misnomer for today's technology. (sitmeanssit.com)

Pilates can help musicians return muscles to their optimal state by performing movements that counteract those held while playing and other unnatural body positions. (internationalmusician.org)

Later, however, research suggested the opposite was true - that it caused muscle fatigue and slower sprinting times in elite athletes. (ndtv.com)
The main sEMG parameters (amplitude and frequency) are prevalently used to evaluate the level of muscle fatigue in static and dynamic contractions. (aaem.pl)
The purpose of this study is to determine and compare 2 separate indices: IF 1 basis of the sEMG signal amplitude analysis and IF 2 basis of the sEMG median frequency analysis, related to muscles fatigue during an isometric contraction. (aaem.pl)

If your muscles should fatigue, rest and continue when you are ready. (howstuffworks.com)
However, recovery time from low-level muscle fatigue after working a 7- to 8-hour day (as in dentistry) is much longer. (dentistrytoday.com)

The research has overwhelmingly demonstrated in physical activity requiring short bursts of power and speed as opposed to long sustained muscle recruitment, a DWU should be utilized to improve athletic performance for multiple individual and team sports (1, 2, 4-6, 8, 9, 11-14).

Over-tensioning is one of the most challenging complications in static medial patellofemoral ligament reconstruction as the graft used for reconstruction is isometric and the anatomical MPFL is a mostly dynamic structure. (springer.com)
As an alternative to established static reconstruction techniques, dynamic graft techniques have been introduced for stabilizing the patella with the aim of providing a more physiological reconstruction of the medial patellofemoral ligament. (springer.com)
Here, we present the protocol of a randomized clinical trial for comparing clinical and biomechanical outcomes of dynamic versus static medial patellofemoral ligament reconstruction. (springer.com)
Patients with recurrent patella dislocation requiring isolated MPFL reconstruction will be recruited and randomized to the dynamic or static reconstruction technique. (springer.com)
The results of the study will clarify whether the reported surgery success for patella stabilization via dynamic MPFL reconstruction is due to muscle contraction or to the passive tenodesis effect combined with clinical outcome measures. (springer.com)
With this study, we will provide much needed information on knee biomechanics after dynamic versus static MPFL reconstruction to provide evidence to support orthopedic surgeons in evidence-based decision-making in their quest for surgical techniques most favorable for their patients. (springer.com)

Dynamic muscle work, on the other hand, creates a healthier environment for bodily repair. (dentistrytoday.com)
Activity patterns at leisure are dynamic contractions of large muscle groups with relatively high intensity and low duration (often less than 1.5 hour), increasing whole body metabolism and cardiac output. (cdc.gov)

What we are not familiar with is the use of different muscle groups that enable us to achieve the said result. (nepalyogahome.com)
Improvement in cardiorespiratory fitness requires physical activity involving large muscle groups at a relatively high level of intensity (>60% of maximal heart rate or maximal oxygen consumption), with continuous duration of at least 3 min. (cdc.gov)
In contrast, occupational physical activities are very seldom performed at such high intensity with large muscle groups over a relatively long continuous duration. (cdc.gov)

Poor flexibility is a common cause of injuries ranging from acute muscle strains to chronic tendonitis. (sports-injury-info.com)

In this muscle contraction, the muscles are generating less force in comparison to the resistance. (nepalyogahome.com)

There are various poses in yoga that allows you to train your muscles. (nepalyogahome.com)
