Flashcards in Chapter 8 - Sport Injuries Deck (103)
what are the 4 types of tissue?
epithelial, muscle, connective and nervous
under a load, tissue experiences ________
under a load tissue experiences deformation
how can deformation be visualized?
deformation can be visualized through the load deformation curve
point where tissue stretches like an elastic band (stretch it, and it goes back with no change)
what is the tissues response to training loads if the training load is less than or equal to the elastic limit?
- micro-failure --> making of new tissue
- positive training effect
what is the tissues response to training loads if the training load is higher than the elastic limit?
- permanent failure
- injury (scar tissue)
what are the 5 forces acting on tissue?
tension, compression, bending, shearing, and torsion
creates a shearing force between the opposing force against the structure
give an example of shearing
blister = caused by the foot rubbing/shearing against the shoe
give an example of tension
when you bend the knee, the tensile force/load is on the hamstring
does tension occur on the concentric or eccentric load?
mostly on the eccentric load
2 part force: compression and tension occur
when is a time we often compress the bones of the legs and feet
what is the name of a fracture from torsion
- received by patient from a health care professional
- promotes healing
- improves quality of injured tissue
- allows quicker return to activity
- therapists restoration of injured tissue and patients participation
- individualized for each athlete
what are the 3 healing phases in order?
1) Inflammatory Response Phase
2) Fibroblastic Repair Phase
3) Maturation-Remodelling Phase
how long does the inflammatory response phase take?
how long does fibroblastic repair phase take?
how long does the maturation-remodelling phase take?
when does inflammation begin?
same time as injury
what are 5 signs of inflammation?
-loss of function
What 5 things do you have to do for inflammation?
-decreases swelling, bleeding, pain and spasms.
true or false: cold gets rid of swelling
FALSE: cold does NOT get rid of swelling, it just helps to reduce/manage pain
does compression make swelling go away?
compression decreases swelling but does not make it go away
what does elevation do for inflammation?
it reduces the amount of accumulation on the other end to decrease swelling
