During Which Type of Stretching Does Viscoelastic Creep Occur?

Viscoelastic creep is a phenomenon that occurs during certain types of stretching exercises. Understanding when and how this occurs can help individuals optimize their stretching routines and prevent injuries. In this brief review, we will explore the positive aspects of viscoelastic creep, its benefits, and the conditions in which it can be used effectively.

Positive Aspects:

  1. Improved Flexibility: Viscoelastic creep allows for greater flexibility by gradually elongating the connective tissues and muscles over time.
  2. Injury Prevention: By gradually applying force to the tissues, viscoelastic creep minimizes the risk of sudden strains or tears, reducing the likelihood of injury.
  3. Enhanced Performance: Increasing flexibility through viscoelastic creep can improve athletic performance, as it allows for a wider range of motion and better movement efficiency.
  4. Rehabilitation Aid: This type of stretching can be beneficial for individuals recovering from injuries or surgeries, as it helps restore flexibility and strength gradually.

Benefits of Viscoelastic Creep:

  1. Elongation of Connective Tissues: Viscoelastic creep promotes the gradual elongation of tendons, ligaments, and fascia. This leads to increased joint mobility and flexibility.

The three-parameter solid element is a Kelvin element (a spring and a dashpot in parallel) in series with a spring. The three-parameter fluid element is a Kelvin element in series with a viscous element (dashpot). Choosing the most appropriate model depends largely on the frequency bandwidth and the strain levels.

How do you measure viscoelastic properties?

In industries such as biomaterials, viscoelasticity is often measured by applying a sinusoidal force, calculating the resulting strain response and determining the elastic-spring-like storage modulus and the flow-like loss modulus. Such dynamic mechanical analysis can be performed as a bench test or deployed in-situ.

What is the three-parameter solid model?

The standard linear solid model, also called SLS model, Zener model, or three-parameter model, is a simplification of the generalized Maxwell model with only one spring-dashpot branch: Figure 3-2: Standard linear solid (SLS) model.

What are the viscoelastic properties?

There are three main characteristics of viscoelastic materials: creep, stress relaxation, and hysteresis. The creep phenomenon is used to describe the continued deformation of a viscoelastic material after the load has reached a constant state (Fig.

What is a 3 parameter item response theory model?

Like all IRT models, it is seeking to predict the probability of a certain response based on examinee ability/trait level and some parameters which describe the performance of the item. With the 3PL, those parameters are a (discrimination), b (difficulty or location), and c (pseudo-guessing).

What is creep in stretching?

Mechanical creep, defined as the elongation of skin with a constant load over time beyond intrinsic extensibility, has been described as the vehicle harnessed for wound closure with presuturing, intraoperative tissue expansion, skin-stretching devices, and skin retraction with undermining.

What is an example of a creep?

Common Instances of Creep Typically, applications that have high heat and high stress can be susceptible to creep. Examples include nuclear power generation, industrial engine components, heated metal filaments, jet engine components, and pressurized high-temperature piping.

Frequently Asked Questions

What are the 3 stages of creep?

Creep curves of metal materials have three stages, known as deceleration (the first), constant (the second) and acceleration(the third) stages respectively. The strain rates of the second stage is constant and relatively small. Therefore the second stage is named as minimum creep rate stage or steady creep stage.

How does creep impact static stretching?

Creep occurs when mechanical length gradually increases in response to a constant stretching force. Viscoelastic stress relaxation during static stretch. Peak torque occurs when muscle first reaches the final stretch position. Final torque is measured at the end of the static stretch holding phase.

What is the psycho physiological concept of stretch tolerance?

Psycho-physiological factors refer to an increased stretch tolerance that allows the individual to accommodate greater stretch-induced discomfort or pain and thus force the joint through a greater ROM (Magnusson et al., 1996; 1997).

What are the 3 types of PNF stretching?

There are three different types of PNF stretches:
  • Contract-Relax Method.
  • Agonist-Contract Method.
  • Contract-Relax-Agonist-Contract Method.

FAQ

What is the passive stretching?
Passive stretching is also referred to as relaxed stretching , and as static-passive stretching . A passive stretch is one where you assume a position and hold it with some other part of your body, or with the assistance of a partner or some other apparatus.
How does PNF stretching differ from static stretching?
Two common methods of stretching in clinical practice are static stretching and proprioceptive neuromuscular facilitation (PNF) stretching. It is generally believed that PNF stretching will result in increased ROM compared with static stretching due to increased inhibition of the targeted muscle.
What type of stretching is PNF?
Proprioceptive Neuromuscular Facilitation (PNF) is a stretching technique utilized to improve muscle elasticity and has been shown to have a positive effect on active and passive range of motions (Funk et al., 2003; Lucas and Koslow, 1984; Wallin et al., 1985).
What is creep effect?
Creep deformation is a form of slow mechanical deformation that occurs when a material is exposed to high-stress levels for a long period of time. Creep is time-dependent. The deformation occurs at a relatively slow rate that can cause a material to fail below its yield point.

During which type of stretching does viscoelastic creep occur?

What is an example of creep in kinesiology? Functional Example: Creep in the lumbar spine can result from prolonged static flexion or vibration (i.e. truck driver in a seated position experiencing sustained oscillatory vibrations of vehicle moving over road).
What is the difference between stretch and creep? Answer: Creep is non recoverable elongation, unlike stretch - which is recoverable elongation. Some elasticity is necessary. Creep is a problem. It can cause the bow to go out of tune and the peep to rotate.
What is creep in physical therapy? Creep is the capacity of fascia and other tissue to lengthen when subjected to a constant tension load resulting in less resistance to a second load application. A progressive deformation occurs over time.

  • What is the creep effect of stretching?
    • Creep is the capacity of fascia and other tissue to lengthen when subjected to a constant tension load resulting in less resistance to a second load application. A progressive deformation occurs over time.
  • What is the relationship between creep and relaxation?
    • Creep is an increase in plastic strain under constant force, while in the case of Stress relaxation; it is a steady decrease in force under constant applied deformation or strain. Creep is a serious issue in plastic housings or snap fit components, while Stress relaxation is a serious issue in sealing elements.
