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%
Lactacid (slow component)- lactic acid removed

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
VO2 max test by multi stage fitness test
RER, compare o2 consumed to co2 produced

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

Q

What are newtons laws, explain

A

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

31
Q

What is wave summation

A

Repeated nerve impulse that doesn’t allow time for full muscle relaxation, therefore contraction gradually increases in strength

32
Q

Definition of spatial summation

A

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
Q

Location and function of Golgi apparatus

A

Between tendon and muscles. Detect muscle tension in isometric contraction cause autogenic inhibition

34
Q

What is autogenic inhibition

A

The sudden relaxing and lengthening of muscles in respond to isometric contraction. Caused by Golgi tendon organ

35
Q

Centre of mass definition

A

Point of balance

36
Q

How to increase stability (4)

A

Line of gravity over support base
Increase weight (more inertia)
Increase area of base support
Lower centre of mass

37
Q

Where are each leaver found?

A

1 overheard throw in, neck extension/flex
2 plantar flexion
3 all other joints

38
Q

Mechanical advantage of lever 1

A

Depends on the distance of the fulcrum from resistance/ effort
Generally large range, fast, weak

39
Q

Enzyme used to convert glycogen and glucose

A

Glycogen phosphorylase

40
Q

Explain what happens in glycolysis

A

Glucose and PFK make pyruvic acid, oxidation occurs turning it to 2 Aceltyl groups and produces CO2

41
Q

What happens to citric acid in the kerb cycle?

A

Oxidative phosphorylation turns it to H which is carried to the ETC
