Module 5 Flashcards
What are the 3 forms of warm ups and what are they focused on?
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.
What is the purpose of Warming up (W-U)
- It prepares you for your workout
- reduces risk of injury
- enhances performance
t or f, the more intense the workout the longer the W-U
True, furthermore large muscle groups benefit more from warming up than fine motor tasks.
How long should a warm up be?
10-20% of workout time
explain how W-U prevents injury by INCREASING THE CORE BODY TEMPERATURE
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!
explain how W-U may improve heart function?
W-U allows the body to prepare for exercise. As a result, during workout you have a reduced risk of electrical abnormalities.
explain how W-U may attenuate (reduce) the effects of DOMS (delayed onset muscle soreness)
it just does…
according to a study.
t or false, there is a of research supporting warming up prevents injury
False
t or f , there is a lot of research supporting that warming up improves performance
True, it increases it 3 - 9%
What are the three effects by which warming up improves performance?
neuromuscular effects
thermal effects
psychological effects
Explain neuromuscular effects of W-U.
A) W-U enhances muscle contraction. allows for quicker, smoother, and more co-ordinated muscle movements
B) W-U speeds up nerve messages. leads to quicker responses + better control
C) increased efficiency of reciprocal innervation. allows opposing muscles to contract and relax faster
explain psychological effects of W-U
W-U improves mental preparedness. Positive imagery can relax an individual and boos concentration.
What is the net effect of neuromuscular effects?
improved proprioception (awareness of body in space) and co-ordination
What are the 3 parts of warm up structure?
1) Progressive exercise
2) stretching
3) active simulation
explain progressive exercise?
Well warming up, gradually increase intensity but never approach actual work out intensity. the goal of this phase to raise core body temp
t or f, stretching prevents injuries
False, only increasing core body temp decreases injuries.
t or f, most muscle injuries occur within normal range of motion and during eccentric movement
True
What are the 4 types of stretching done in warm up?
1) none - no stretching is required in warm up for body weight supported activities
2) dynamic stretching: essentially is active movement
3) static stretching
4) both dynamic and static
What is dynamic stretching?
constant movement of the body with a gradual increase in range and speed so at the end ROM is never exceeded
what is Ballistic stretching?
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)
what is static stretching?
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.
what is the difference
between static stretching and dynamic stretching in W-U.
dynamic stretching enhances performance
long duration static stretching decreases performance.
T or f, with flexibility, pain = more gain
false, pain = no gain
pain indicates you are tearing muscle fibers
explain free/active static stretching.
no assistance is involved (no external forces). This stretch should be held for 6 seconds or less in warm up. (15 - 30 seconds in cool down)
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.
T or f, Active stretching produces greater gains in flexibility that can be maintained for 4 weeks which passive stretching cannot do.
true
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.
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.
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.
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
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
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
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.
What would occur if an agonist muscle and antagonist muscle contracted at once.
A pulled muscle, typically the weaker of the 2 muscles pulls.
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.
What does a sudden stop in activity lead to?
blood pooling and a drop in BP that can cause fainting.
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.
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
