27
Q

What happens if you lack mobility in one joint? ex ankle

A

Your body will try and compensate for this lack of mobility and will affect joints up the chain
ex. affects knee

28
Q

Activation

A

Isolate a specific muscle group/position through forceful contraction

29
Q

Post activation potentiation (PAP)

A

Enhancement of one agent so that the combined effects is greater than the sum of the effects of each alone

30
Q

How does potentiation work?

A

Creating fast, dynamic movement prior to training to increase the nervous system output to carry over to training sessions performed at submaximal energy

31
Q

What is potentiation specific to?

A

Upcoming task

32
Q

Example of potentiation

A

Loaded jump squat before back squatting

33
Q

Guidelines for RAMP warm up

A

Soft tissue work
Raise heart rate (3-5 min)
Mobilize (4-8 exercises)
Activation (3-5 exercises)
Potentiation (1-3 exercises)

34
Q

Stretch reflex

A

The reaction of the efferent motor neuron to cause a rapid contraction created by the stimulation of the muscle spindle

35
Q

Static stretching

A
  1. Muscle quickly stretched, activating muscle spindle
  2. Stretch reflex engaged causing a contraction of that muscle, protects it from being pulled forcefully or beyond its normal range of motion.
  3. Perform static stretches slowly to avoid activating the stretch reflex
36
Q

Autogenic inhibition

A

Injury preventing relaxation via GTO that occurs in the same muscle that is experiencing increased tension

37
Q

How long does autogenic inhibition take?

A

7-10 s

38
Q

Reciprocal inhibition `

A

Relaxation that occurs in the opposing muscle of which is experiencing increased tension

39
Q

Proprioceptive neuromuscular facilitation stretching (PNF)

A

Using both passive and active components to improve ones ROM
Tricking your body to allow for a greater ROM, bypassing stretch reflex

40
Q

3 variations of proprioceptive neuromuscular facilitation

A

1) Hold-Relax
2) Contract-relax
3) Hold relax with agonist contraction

41
Q

Hold-relax

A

Passive pre-stretch for 10s
Isometric contraction against resistance for 6s (person pushing)
Allows for a deeper passive stretch for 30s bc of autogenic inhibition

42
Q

How long should a passive pre-stretch be?

A

10 s till mild discomfort

43
Q

Contract-relax

A
  1. Contract a muscle against resistance as hard as possible through a full ROM to activate the GTO
  2. Stop the contraction and the GTO assists in muscular relaxation
  3. Utilize relaxation to push a passive stretch further than normal
44
Q

Hold-relax with agonist contraction

A
  1. Apply stretching force to a limb (ex. hamstring)
  2. Activate the opposing muscle group that you are stretching (ex quad)
  3. Increased relaxation of stretched muscle, can stretch further due to reciprocal inhibition
45

A

2x per week for a minimum of 5 weeks

47
Q

FITT- intensity

A

Mild discomfort

48
Q

FITT- time

A

15-30s

49
Q

FITT- type

A

Static, dynamic and PNF

50
Q

When should we do static stretching?

A

Post exercise
BUT pre-exercise is ok as long as it is followed up by activation

51
Q

What should we begin all stretching with?

A

Period of general activity to raise temp

52
Q

Methods of improving mobility

A

Functional range conditioning
Resistance training

53
Q

Functional range conditioning

A

Lift offs
CAR’s/ axials
PAIL’s and RAIL’s

54
Q

Resistance training

A

Training through a full range of motion
Eccentric and isometric focus

55
Q

Lift-offs

A

Utilize isometric contractions to create strength and motor control at end ranges of motion

56
Q

Goal of lift offs

A

Make passive ROMs become active ROMs

57
Q

CARs/Axials

A

Utilize active rotation movements at outer limits of your range of motion for each individual joint to improve neurological control

58
Q

What does CAR’s stand for?

A

Controlled articular rotations

59
Q

What does CAR’s/axials improve?

A

Joint stability and kinesthetic awareness

60
Q

What does PAILS stand for?

A

Progressive angular isometric loading

61
Q

What does RAILS stand for?

A

Regressive angular isometric loading

62
Q

Goal of PAILS and RAILS

A

Create active control from your passive range of motion by stimulating the nervous system to contract/relax, developing strength and resilience in the newly acquired range

63
Q

How long should PAILS and RAILS take?

A

1 min static: 10-20 PAILS: 10-20s RAILS: 2 min static

64
Q

What does resistance training improve?

A

Joint mobility

65
Q

How does resistance training improve mobility?

A

By performing exercises through a full ROM

66
Q

Progressive vs regressive stretching

A

Progressive= pushing down in to ground
Regressive pull up towards body
