What are the 3 forms of warm ups and what are they focused on?

A

1) passive warm up
- increases body temp by external means (heat pack)
2) general warm up
- increases body temp by non-specific body movements
3) specific warm up
- increases body temp by actively using body parts that will subsequently be used in more strenuous activity.

Q

explain how W-U prevents injury by INCREASING THE CORE BODY TEMPERATURE

A

this lowers activation energy of metabolic rxns, it increases blood flow, it increases the speed of nerve impulses and more.

increased body temp makes muscles more elastic and releases synovial fluid into joints!

Q

what is Ballistic stretching?

A

This form of stretching involves bouncing. It tries to exceed your bodies range of motion. This stretching is not recommended b/c it increases risk of injury by initiating the stretch reflex. (causes stretched muscles to contract)

Q

what is static stretching?

A

two types of SS
1) free/active static
2) passive static
static stretches should not be held for more than 6 second. Any more and it decreases motor neuron ability.

25
explain passive stretching
an external force is applied which allows one to exit ROM. The stretch cannot be applied too quickly otherwise the stretch reflex will occur.
26
T or f, Active stretching produces greater gains in flexibility that can be maintained for 4 weeks which passive stretching cannot do.
true
27
explain part 3 of the warm up structure: Activity simulation
The warm up must mimic the purpose of the training session. Warm up intensity should get near work out intensity.
28
In what category (warm up, work out, and cool down) can dynamic stretching be done?
Dynamic stretching can only be done in W-U and workout.
29
In what category (warm up, work out, and cool down) can static stretching for 6 seconds or less be done?
6 seconds or less static stretching can only be done in W-U and work out.
30
In what category (warm up, work out, and cool down) can dynamic plus static stretching for 6 seconds or less be done?
dynamic stretching coupled with SS for less than 6 seconds can only be done in W-U and workout
31
In what category (warm up, work out, and cool down) can static stretching for more than 6 seconds be done?
SS for more than 6 seconds can only be done in the cool down OR (ONLY IF THE WARM UP IS 15 - 20 MINUTES LONG) in warm up too
32
What is an agonist muscle? what is an antagonist muscle?
Agonist muscle = typically the primary mover. It is the muscle that is being used. Antagonist= the muscle opposite to the agonist
33
What is reciprocal inhibition?
Reciprocal inhibition is a neuromuscular reflex. Essentially an increase in neural drive in a muscle reduces functional activity in that muscles antagonist. IF THE AGONIST MUSCLE IS CONTRACTED, THE ANTAGONIST MUSCLE MUST BE RELAXED.
34
What would occur if an agonist muscle and antagonist muscle contracted at once.
A pulled muscle, typically the weaker of the 2 muscles pulls.
35
During the workout, focus should be on stretching the antagonist muscle. Why?
A muscle pull occurs b/c the antagonist is being eccentrically stretched. By stretching the antagonist muscle, it prepares for a load and therefore increases agonist efficiency.
36
What does a sudden stop in activity lead to?
blood pooling and a drop in BP that can cause fainting.
37
What is the Cool down?
Muscle activity aids in pushing blood back to the heart from the extremities. longer duration stretching of 15 seconds or more should be done to inhibit alpha motor neurons and thereby promote relaxation. (remember Static stretching for more than 6 seconds reduces motot neuron effects. Therefore this type of stressing is not wanted in warm up but it is necessary in cool down.
38
What is the purpose of the cool down?
to allow muscles to return to normal resting length. this in turn speeds up recovery. Cool down is the best time to work on flexibility b/c body temp is so high
39
What is the only thing that has been scientifically proven to be a result of the cool down?
it avoids blood pooling
40
what do both coaches and researchers agree on about cool down stretches?
that it does NOT prevent DOMS (delayed onset muscle soreness)
41
what are the two primary stretches used in cool down?
Long hold free static and PNF (proprioceptive neuromuscular facilitation)
42
What is Proprioceptive neuromuscular facilitation (PNF)
AKA muscular energy technique. the goal of PNF is to modify neuromuscular processes and the response of stretch receptors that control tissue tension. The 2 main approaches to PNF are 1) contract - relax 2) contract - relax - contract
43
Explain PNF approach | 'contract - relax'
1) Bring the muscle being stretched to the end of its ROM and hold for 10 - 15 seconds. 2) After stretching initiate an isometric contraction (contraction that does not change muscle length) at 20 -50% of max contraction for 6 - 15 seconds. 3) then allow muscle to relax 4) repeat the process of stretch - contract - relax at least 3 times, EACH TIME WITH GREAT ROM.
44
Explain PNF approach | 'contract - relax - contract'
Same as 'contract -relax' approach but after the relaxation phase, a CONTRACTION against the ANTAGONIST is also done to initiate reciprocal inhibition which promotes the relaxation of the agonist. This should be repeated 3 times each time with greater ROM.
45
If Flexibility needs to be developed quickly what form of stretching should be used?
PNF, it can increase flexibility by 33 %! Remember however, PNF should only be done in cool downs.
46
T or f, training increases the point at which the stretch reflex occurs?
True,
47
What is: inverse myotatic reflex? (IMR)
A FUCKING BUILT IN SAFTEY SYSTEM TO PREVENT OUR MUSCLES FROM TEARING, wee hoo. If stretch receptors sense too much stretching (tension) they auto initiate a relaxation response
48
What are we suppose to stretch?
muscle and deep fascia. | NEVER stretch tendons or ligaments. Stretching ligaments can cause joint laxity (chronic pain due to loos ligaments)
49
What are the benefits of a regular stretching program ( W-U and C-D)
- reduced muscle tension - less aches and pains - increased ROM - increased circulation which provides increased energy levels - improved posture - better state of mind
50
T or f, always stretch to warm up
False, W-U is prior to stretching always
51
t or f, each stress should be repeated at least 2 times
True, creates muscle memory
52
Explain factors that influence flexibility: Joint structure
type of joint dictates what types of motion are possible ball - socket = 3 planes hinge = 1 plane
53
Explain factors that influence flexibility: Muscular imbalance
muscle strength and length imbalances reduce flexibility
54
Explain factors that influence flexibility: Muscular control
For some movements there is a certain amount of strength required to simply achieve ROM ( e.g hip abductions)
55
Explain factors that influence flexibility: Age
Flexibility Increases from 6 - 18 stabilizes from 18- early 20'2 decreases after early 20's ( unless maintained)
56
Explain factors that influence flexibility: Gender
woman > men
57
Explain factors that influence flexibility: muscular temperature
warm muscles stretch better
58
Explain factors that influence flexibility: Body composition
Adipose tissue limits ROM. IT IS A MYTH THAT TOO MUCH MUSCLE BULK LIMITS FLEXIBILITY.
59
Explain factors that influence flexibility: Activity level
Active individuals are normally more flexible
60
Explain factors that influence flexibility: Time of day
ROM tends to be greater in the evening. Max flexibility occurs at mid day and mid night
61
Explain factors that influence flexibility: Disease / Injury
Although it limits ROM, exercise should still be done to maintain the joints ROM.
62
What is Kyphosis?
A forward hunched over posture. This occurs if muscles in the front of the body are shortened which pulls everything forward. (lack of exercise causes muscles to shorten). Can also occur if an individual does to many pushing exercises and not enough pulling exercises.
63
What is Upper Crossed Syndrome?
when shoulders are constantly pulled forward, the upper-middle back muscles lengthen and become weak causing the spine to become excessively curved.
64
Gender specific muscle imbalances: Tight Piriformis
This is a deep butt muscle that rotates the hip. | A tight Piriformis is more common in MEN. It can cause knee problems
65
Gender specific muscle imbalances: The Adductors
Adductors squeeze the thighs together. WOMAN who sit cross legged can develop tight adductors. Can cause knee pain. Tight adductors are prevalent in knock-kneed ppl
66
Gender specific muscle imbalances: Tight Calves
WOMAN who wear high heels are prone to this. This is shown by flattened, externally rotated feet. Tight calves can be a leading cause in plantar fasciitis and other painful foot and ankle problems
67
Gender specific muscle imbalances: Lordosis (inward curvature of spine)
This can result from overworking the quads without including hamstring workouts too.
68
What are some reasons for shortened muscles / trigger points (of muscle reflex)
- feeling cold - stress - bad posture - static load(carry heavy backpack) - sitting cross legged / prolonged sitting. - extended sleep in bad position
69
Explain Tonic (postural) muscles.
They react to faulty loading by shortening and tightening. (think tonic = tight) they are prone to hyperactivity LATE susceptibility to fatigue they support the body against gravity
70
Explain Phasic (postural) muscles
React to faulty loading by lengthening and weakening!!! they are prone to inhibition EARLY susceptibility to fatigue They eccentrically work against gravity.
71
T or f, stretching a tight short tonic muscle will auto improve the function and balance of a phasic muscle antagonist?
True, remember: if its not tight, dont stretch it
72
Explain: foam roll 5-min
Decreases tonic activity in muscle | breaks down muscle adhesions and causes fascia to relax. ( known as a myo-fascial release)
73
Explain voodoo flossing
A form of myo-fascial release that can be used on muscles and tendons. It uses a band that wraps around the targeted muscle. IT is very painful but it has instant results!
74
explain a dynamic warm up
Involves continuous sport specific movement with interspersed dynamic stretches. IT follows RAMP
75
WHAT IS RAMP?
R - raise core body temperature A - activate muscles being used M - mobilize the muscles being used P- potentiate (CNS activation) muscles being used. Used in dynamic warm ups
76
How long do you stay with a stretch?
until the body is balanced
77
