What Is Sprain And Strain In Physical Education
Overview – A sprain is a stretching or tearing of ligaments — the tough bands of fibrous tissue that connect two bones together in your joints. The most common location for a sprain is in your ankle. Initial treatment includes rest, ice, compression and elevation.

  • Mild sprains can be successfully treated at home.
  • Severe sprains sometimes require surgery to repair torn ligaments.
  • The difference between a sprain and a strain is that a sprain injures the bands of tissue that connect two bones together, while a strain involves an injury to a muscle or to the band of tissue that attaches a muscle to a bone.

Most ankle sprains involve injuries to the three ligaments on the outside of your ankle. Ligaments are tough bands of tissue that stabilize joints and help prevent excessive movement. An ankle sprain occurs when you roll, twist or turn your ankle in an awkward way.

What is sprain definition?

Definition – A sprain is an injury to the ligaments around a joint. Ligaments are strong, flexible fibers that hold bones together. When a ligament is stretched too far or tears, the joint will become painful and swell.

What is the difference between strain and sprain Class 12 physical education?

What Are Strains and Sprains? – A strain is when a muscle or tendon (tissue that attaches muscle to bone) is stretched too far. A strain is sometimes called a “pulled muscle.” Depending on the level of muscle strain, it may heal within a few weeks, but reinjury can happen.

How do you identify a sprain and strain?

Check if you have a sprain or strain – It’s likely to be a sprain or strain if:

  • you have pain, tenderness or weakness – often around your ankle, foot, wrist, thumb, knee, leg or back
  • the injured area is swollen or bruised
  • you cannot put weight on the injury or use it normally
  • you have muscle spasms or cramping – where your muscles painfully tighten on their own

What are the 2 types of strains?

Strain – So far, we’ve focused on the stress within structural elements. When you apply stress to an object, it deforms, Think of a rubber band: you pull on it, and it gets longer – it stretches, Deformation is a measure of how much an object is stretched, and strain is the ratio between the deformation and the original length.

  1. Think of strain as percent elongation – how much bigger (or smaller) is the object upon loading it.
  2. Just like stress, there are two types of strain that a structure can experience: 1.
  3. Normal Strain and 2.
  4. Shear Strain,
  5. When a force acts perpendicular (or “normal”) to the surface of an object, it exerts a normal stress.

When a force acts parallel to the surface of an object, it exerts a shear stress. Let’s consider a rod under uniaxial tension. The rod elongates under this tension to a new length, and the normal strain is a ratio of this small deformation to the rod’s original length. What Is Sprain And Strain In Physical Education Strain is a unitless measure of how much an object gets bigger or smaller from an applied load. Normal strain occurs when the elongation of an object is in response to a normal stress (i.e. perpendicular to a surface), and is denoted by the Greek letter epsilon. Clearly, stress and strain are related. Stress and strain are related by a constitutive law, and we can determine their relationship experimentally by measuring how much stress is required to stretch a material. This measurement can be done using a In the simplest case, the more you pull on an object, the more it deforms, and for small values of strain this relationship is linear. This linear, elastic relationship between stress and strain is known as Hooke’s Law, If you plot stress versus strain, for small strains this graph will be linear, and the slope of the line will be a property of the material known as Young’s Elastic Modulus, This value can vary greatly from 1 kPa for Jello to 100 GPa for steel. For most engineering materials, the linear region of the stress-strain diagram only occurs for very small strains (<0.1%). In this course, we will focus only on materials that are linear elastic (i.e. they follow Hooke's law) and isotropic (they behave the same no matter which direction you pull on them). What Is Sprain And Strain In Physical Education From Hooke’s law and our definitions of stress and strain, we can easily get a simple relationship for the deformation of a material. Intuitively, this exam makes a bit of sense: apply more load, get a larger deformation; apply the same load to a stiffer or thicker material, get less deformation. If the structure changes shape, or material, or is loaded differently at various points, then we can split up these multiple loadings using the principle of,

What causes sprain and strain?

Most sports injuries, such as sprains or strains, are caused by minor trauma.

Sprains are ligament injuries resulting from wrenching or twisting a joint. Strains are injuries to a muscle or tendon, and are often caused by overuse, force, or stretching. The ankle is the most commonly sprained or strained joint.

What is strain injury example?

Strains – A strain is an injury to a muscle and/or tendon. Tendons are fibrous cords of tissue that attach muscles to bone. Strains often occur in the back or leg (typically, the hamstring). Similar to a sprain, a strain may be a simple stretch of your muscle or tendon, or it may involve a partial or complete tear of the muscle and tendon.

  • Symptoms of a strain may include pain, muscle spasm, muscle weakness, swelling, inflammation, and cramping.
  • Soccer, football, hockey, boxing, wrestling and other contact sports put athletes at risk for hamstring strains, as do sports that feature quick starts, such as hurdling, long jumping, and running races.

Gymnastics, tennis, rowing, golf and other sports that require extensive gripping have a high incidence of hand sprains. Elbow strains frequently occur in racquet, throwing, and contact sports. The recommended treatment for a strain is the same as for a sprain: rest, ice, compression and elevation.

What is strain and its types?

Types of Strain – Strain is defined as the ratio of change in dimension to the original dimension when a force is applied to the body. There are different types of strain, such as longitudinal or normal strain, lateral strain, shear strain and volumetric strain.

    What are the three types of strains?

    Explain different types of strain. Answer Verified Hint: There are three types of strain namely normal or longitudinal strain, shearing strain and volumetric or bulk strain which have been categorized on the basis of type of distortion produced by them. Although all of them define some kind of distortion but they are quite different from each other.

      Complete answer: Note:

    The three types of strain are as follows:1.Normal strain or longitudinal strain: Normal strain is the ratio of change in length of a body to the original length of the body. It is also known as longitudinal strain because it is concerned with the change in length of the body and its original length.

    Mathematically it can be expressed as:$ }_ }=\dfrac $2.Shearing strain: Shearing strain as defined as the angular distortion produced in the body which means that it is the ratio of the displacement of the surface of the body and the height of the body, but remember that the surface of the body is the one on which the stress is acting.

    Mathematically it can be expressed as:$ }_ }=\dfrac $3.Volumetric strain or bulk strain: Volumetric strain is the ratio of the change in volume of a body and its original volume. It is also known as bulk strain because it considers the whole volume of the body.

    • Mathematically it can be expressed as:$ }_ }=\dfrac $Strain is the deformation produced in a body when stress is applied to it.
    • As explained above, strain is the change is length, angle and volume of a body.
    • But remember that strain is only produced when an external force is applied on the body, no strain will be developed due to internal forces.

    What signs and or symptoms would differentiate between a strain and a sprain?

    Similar Symptoms – Sprains and strains share similar symptoms, including:

    Pain (the most common) Swelling Loss of mobility

    Range of motion is negatively affected with both conditions, and though you may be able to function, range of motion in the sprained or strained area is limited. The only difference between symptoms of sprains and strains is that sprains cause bruising, and strains do not. Strains affect muscle and lead to muscle spasms instead.
