Quiz

Question 1

elasticity

Answer 1

The ability of a structure to return to its normal length after application of an elongation force or load.

Question 2

Vicosity

Answer 2

Viscosity is the resistance to an outside force the cause of fluid-like, permanent deformation

Question 3

Viscoelasticity

Answer 3

Ability to resist a change of shape when to an outside load but inability to completely revert to previous state.

Question 4

Plasticity

Answer 4

The ability of a substance to undergo permanent change in size and shape.

Question 5

Creep

Answer 5

Elongation of tissue which occurs over constant low level loading

Question 6

Stress

Answer 6

Force that changes the shape

Question 7

Strain

Answer 7

Amount of deformation a structure undergoes when a force is applied

Question 8

Volume

Answer 8

Quantity measure of work performed.-km covered by runners /cyclist/rowers
-sets reps average load weight lifters

Question 9

Intensity

Answer 9

Measure of quality of work performed.
Speed employed by runner cyclist/rowers
%1Rm for weight lifters

Question 10

Frequency

Answer 10

A measure of how often one trains
3-12 session per week
2-3 sessions per body part for resistance training

Question 11

After an Acute injury

Answer 11

RICER
Protect, resist activity (rest, but keep other parts active, ice, compression, elevation)
Control pain
Maintain CRF

Question 12

Hysteresis

Answer 12

Repetitive stretching increases
Temperature and ROM
propioceptive neuromuscular facilitation’s

Question 13

Muscle spindles

Answer 13

Lie between extrafusal muscle fibres 
Sensitive to stretch 
Muscles fibres containing muscle spindles are intrafusal muscle fibres
Alpha and beta gamma nerves
Ia,1b and II afferent/sensory 
Less = more precise movements

Question 14

Golgi tendon organs

Answer 14

Sensitive to contraction and tension in muscle

Located @ musculotendinous junction contain 1b nerves

Question 15

Stretching technique

Answer 15

Static
Dynamic
Ballistic

Question 16

Propioceptive neuromuscular facilitation (PNF)

Answer 16

CR
Contract muscles in position of stretch
Relax and stretch further
Repeat starting from position of greater stretch

CRAC
Contract of muscles in position of stretch
Relax and stretch further while contracting against antagonist
Repeat starting from position of greater stretch

Question 17

PNF stretching explained

Answer 17

1. Autogenic inhibition occurs when the GTOs send inhibitory facilitation because the muscle either contracts or stretches
2. Reciprocal inhibition one muscle contracts, the other relaxes.
3. viscoelastic properties succumb to creep.
4. The gate- control theory of pain. Pain sensitivity decreases over time

Question 18

Benefits of stretching

Answer 18

• Flexibilty
• ROM
• Relexation
• May prevent injury risk but can decrease other physical attributes - data conflicting

Question 19

Other techniques ROM and flexibility

Answer 19

• Massage
• Heat
• Foam rolling
• tennis balls
• manipulations

Question 20

Measuring Flexibility and ROM

Answer 20

Tape measure 
Geniometers
Electrogoniometers
Bio mechanical analyses 
Sit and reach bench

Question 21

Hold stretch for atleast 15

-45 seconds

Answer 21

The groups holding stretches for 15 seconds demonstrated increased flexibility during AROM compared to 5 second group

May need to hold up to 20 mins for contractions
