1

what are the 4 types of tissue?

epithelial, muscle, connective and nervous

2

under a load, tissue experiences ________

under a load tissue experiences deformation

3

how can deformation be visualized?

deformation can be visualized through the load deformation curve

4

elastic region

point where tissue stretches like an elastic band (stretch it, and it goes back with no change)

5

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

6

what is the tissues response to training loads if the training load is higher than the elastic limit?

- permanent failure
- injury (scar tissue)

7

what are the 5 forces acting on tissue?

tension, compression, bending, shearing, and torsion

8

shearing

creates a shearing force between the opposing force against the structure

9

give an example of shearing

blister = caused by the foot rubbing/shearing against the shoe

10

tension

tensile force/load

11

give an example of tension

when you bend the knee, the tensile force/load is on the hamstring

12

does tension occur on the concentric or eccentric load?

mostly on the eccentric load

13

bending

2 part force: compression and tension occur

14

when is a time we often compress the bones of the legs and feet

when walking

15

torsion

screw/unscrew. twisting

16

what is the name of a fracture from torsion

spiral fracture

17

treatment

- received by patient from a health care professional
- promotes healing
- improves quality of injured tissue
- allows quicker return to activity

18

rehabilitation

- therapists restoration of injured tissue and patients participation
- individualized for each athlete

19

what are the 3 healing phases in order?

1) Inflammatory Response Phase
2) Fibroblastic Repair Phase
3) Maturation-Remodelling Phase

20

how long does the inflammatory response phase take?

2-4 days

21

how long does fibroblastic repair phase take?

hours-6 weeks

22

how long does the maturation-remodelling phase take?

3 weeks-years

23

when does inflammation begin?

same time as injury

24

what are 5 signs of inflammation?

-redness
-swelling
-pain
-increased temperatures
-loss of function

25

What 5 things do you have to do for inflammation?

-protect
-rest
-cryotherapy
-compression
-elevation

26

cryotherapy

-decreases swelling, bleeding, pain and spasms.
-cold/ice

27

true or false: cold gets rid of swelling

FALSE: cold does NOT get rid of swelling, it just helps to reduce/manage pain

28

does compression make swelling go away?

compression decreases swelling but does not make it go away

29

what does elevation do for inflammation?

it reduces the amount of accumulation on the other end to decrease swelling

30

4 things that happen during the Fibroblastic Repair Phase are?

1) repair ad scar formation
2) granulation tissue fills the gap
3) collagen fibres are deposited by fibroblasts
4) signs seen in the phase1 subside
