What are intrinsic and extrinsic risk factors?

What are intrinsic and extrinsic risk factors?

Extrinsic factors are external to the individual and can include variables such as the type of sport, exposure to the sport, training, and playing environment [1]. Intrinsic factors are internal personal factors that can be further dichotomised into modifiable and non-modifiable risk factors.

What are some risk factors for injury or strain of the hamstring?

Hamstring injury risk factors include:

• Sports participation. Sports that require sprinting or running, or other activities such as dancing that might require extreme stretching, make a hamstring injury more likely.
• Prior hamstring injury.
• Poor flexibility.
• Muscle imbalance.

What are some 3 extrinsic factors with injury risk?

Extrinsic Risk Factors Sports factors (e.g. coaching, rules, referees) Protective equipment (e.g. helmet, mouth guard, shin guards) Sports equipment (e.g. shoes, ski’s, racquets)

What is a muscle or tendon strain?

A muscle strain is an injury to a muscle or a tendon — the fibrous tissue that connects muscles to bones. Minor injuries may only overstretch a muscle or tendon, while more severe injuries may involve partial or complete tears in these tissues.

What are intrinsic factors in sport?

Intrinsic, or person-related, factors include muscle strength, flexibility, balance and biomechanics.

How long does it take for a strained hamstring to heal?

Recovery from a hamstring tear or strain Mild to moderate (grade 1 or 2) tears or strains can heal within three to eight weeks with diligent home therapy. For a grade 3 hamstring tear or strain, recovery may be as long as three months.

What is the difference between intrinsic and extrinsic injury risk factors?

Intrinsic factors were defined as factors associated with the athletes’ individual characteristics, such as anthropometric measurements, nutrition and psychological factors 1; extrinsic factors were defined as factors related to the environment, climate, equipment and training 1.

What are the risk factors for hamstring muscle strain injury in sport?

A systematic literature search was conducted of Medline, CINAHL, Embase, AMED, AUSPORT, SPORTDiscus, PEDro and the Cochrane library from inception to August 2011. Where possible, key words ( table 1) derived from the research question were mapped to subject headings (Supplemental file).

Which is an intrinsic example of a sporting injury?

The following intrinsic examples are flexibility: The flexibility: can cause a sporting injury because by trying to over stretch a muscle or trying to perform a move which requires the joints that are not attached very well.

What causes weakness in the hamstring and thigh?

10 Both reviews identified hamstring muscle weakness and thigh muscle imbalance, muscle flexibility, previous hamstring injury, other previous injury and age as potential risk factors; however, these reviews concluded that single variables were inconsistently identified as associated factors.

How are intrinsic and extrinsic risk factors related?

An Intrinsic risk factor us is a risk or force from the body. So these would be internal forces, which are stresses from within the body. Intrinsic factors are variables that you are able to prevent yourself from an injury.

What are the risk factors for a hamstring injury?

The risk factors for hamstring injuries include: 1-6 Previous hamstring injury. People who have suffered a hamstring injury in the past are at the greatest risk of future hamstring injuries. Muscle weakness and fatigue. If a muscle is weak or fatigued it can alter a person’s biomechanics and may increase risk of injury.
