Q

Components of EPOC, what happens in each and for how long?

A

Alactacid (fast component) - O2 replen to resaturate myoglobin (2min), PC and haemoglobin
PC replen- 30seconds 50%, 3min 100%

Q

How is lactic acid removed? How long does it take

A

Lactacid stage (slow component)
.Converted into pyruvic acid and oxidised into co2 and h2o if o2 present
.transport via blood to liver, convert to glycogen
. Convert to protein
.Remove by sweat/urine
50% take half an hour, 100% many hours

Q

Methods to measure energy consumption, how?

A

Indirect calorimeter, measure co2 production at rest/exercise, indicate vo2 max, lots of equipment
Lactate sample

Q

Stages of plyometric

A

.Eccentric (pre stretch), muscle lengthen under tension storing elastic energy
.Amortisation time between leg bending and contracting to jump. Should be as short as possible
.Concentric, muscles contract and stored energy used to force athlete off the ground

25
Explain vygotsky theory
Social development theory Constructivism, learn by MKO, inter and intra, zone of proximal development to asses (what I can do, what I do with help, what i can’t do)
26
What are newtons laws, explain
Inertia, in order to change objects state of motion an external force is required to overcome its inertia (resistance to change in motion) Acceleration, A x mass = force, the magnitude and direction of a force will determine the direction and magnitude of the acceleration Action Reaction, Ground reaction force
27
4 internal consequences of smoking
Inflammation in respiratory system cause narrowing Carbon monoxide bind to Hb Reduced alveoli SA Cilia damage cause coughing due to mucus build up Chronic obstructive pulmonary disease
28
Type 1 muscle name and characteristics
Slow oxidative, small motor neurone, lots of mitochondria myoglobin and capillary
29
Type a and b muscle name and characteristics
A- fast oxidative glycolytic | B fast glycolytic, large motor neurone bodies, opposite to slow oxidative
30
Methods to increase muscle contraction strength
Higher frequency, recruit type 2b and large motor units
31
What is wave summation
Repeated nerve impulse that doesn’t allow time for full muscle relaxation, therefore contraction gradually increases in strength
32
Definition of spatial summation
When multiple motor units are recruited at different times to make a sustained contraction, shares work load so individual motor units don’t fatigue
33
Location and function of Golgi apparatus
Between tendon and muscles. Detect muscle tension in isometric contraction cause autogenic inhibition
34
What is autogenic inhibition
The sudden relaxing and lengthening of muscles in respond to isometric contraction. Caused by Golgi tendon organ
35
Centre of mass definition
Point of balance
36
How to increase stability (4)
Line of gravity over support base Increase weight (more inertia) Increase area of base support Lower centre of mass
37
Where are each leaver found?
1 overheard throw in, neck extension/flex 2 plantar flexion 3 all other joints
38
Mechanical advantage of lever 1
Depends on the distance of the fulcrum from resistance/ effort Generally large range, fast, weak
39
Enzyme used to convert glycogen and glucose
Glycogen phosphorylase
40
Explain what happens in glycolysis
Glucose and PFK make pyruvic acid, oxidation occurs turning it to 2 Aceltyl groups and produces CO2
41
What happens to citric acid in the kerb cycle?
Oxidative phosphorylation turns it to H which is carried to the ETC
42
Components of the decisions making
Detection Comparison Recognition
43
What is the translators mechanism
Input is compared to already coded info so decision can be made
44
Whitings model explain
``` Input from display Receptor system Perceptual mechanism (filter) Translatory mechanism Effector system Output ```
45
Who believes core principles are used and adapted to specific stimulus
Schmidt
46
Components of Schmidt schema model
``` RECALL SCHEMA: Initial condition (info from display) Response spec (choose what to do) ACTION RECOGNITION SCHEMA: Sensory consequence (feel) Response outcome (feedback of result) ```
47
What is after the AVN?
Bundle of his then bundle branches
48
Methods to increase memory (6)
``` Focus Reward Repetition Motivation Chunking Chaining ```
49
What controls BP and shunt mechanism
Vaso motor centre in the medulla oblongata
50
Causes for hicks law
Single channel hypothesis (one stimuli at a time) | Psychological refractory period (delay when processing 2nd stimuli due to 1st still being processed)
51
3 features/ jobs of UK sport
Lottery money World class performance program Talent ID
52
What is gold4girls
A world class performance programme
53
Who does sports science research? What is the research used for
National institute of sport Talent ID World class performance programme
54
Features of an efficient talent programme
``` Testing facilities Analyse Link between sport and programme Equal opportunity National development squad Trained talent spotters ```
55
Key word for win at all costs
Win ethic
56
Devine negligence
Conduct that falls below reasonable persons standards and leads to breach of duty and harm
57
Define duty of care
Legal obligation imposed on someone if responsible for group
58
Loco parentis meaning
In place of parent, authority assigned to adult who taking care of child
59
Legislation examples
Fire safety act- stands made out of material Football offence act- no missiles, no racist chants, no field trespassing Sporting event act- no alcohol
60
Impulse equation
Time x force Ns
61
Uses of video analysis
Analysis opponents, predict, biomechanics, talent spotting
62
What equipment is used in indirect calorimeter, what due it measures
Metabolic art, co2 and o2
63
Dara integrity meaning
Ensure data is accurate and up to date
64
How to ensure data integrity
``` Service equipment Reduce access Back up data Security Virus protection ```
65
Momentum equation
Velocity x mass
66
Factors affect friction
Temp Mass Surface type of bodies
67
Trajectory meaning
Path followed by a projectile. Highl low
68
Angular momentum equation
Moment of inertia x angular velocity
69
What is moment of inertia inversely proportional to
Angular velocity
70
Equation for moment of torque and units
Newton meters | Force N x perpendicular distance of force from fulcrum m
71
Name for delay in response to second stimuli following first
Psychological refractory period
72
What is Gestalts theory, what doe it believe
Insight learning, cognitive theory use past experiences to solve problem, sudden realisation, gestalt means entirety in German
73
Who did schema theory
Schmidt
74
Name of vygotskys theory, describe
Social development theory, constructivism, learn from MKO, inter vs intra psychological learning and zone of proximal development
75
Newtons 2nd law
