23
Q

inertia

A

resist of a body to change its state of motion

24
Q

age affecting aerobic power

A

peak at 20 yrs
⬇️ elasticity of lungs = ⬇️haemoglobin and tf ⬇️ mitochondria tf ⬇️ 02 in, around and to muscles

25
Q

what do movement patterns determine ??

A

FC And ES

26
Q

2 benefits of continuous training

A

↑ aerobic power and recovery
best for beginners = ↓ risk of injury / ↓ equip

27
Q

how does muscle fibre type affect musc strength ??

A

↑ FAST twitch = ↑ size of muscle fibre type = ↑ force = ↑ contraction against resistance

28
Q

what does AVO2 diff give an indication of??

A

how much o2 muscles use

29
Q

describe fartlek training

A

type of continuous training
20+ min
↑er and ↓er intensities. inside and outsdide ATZ

30
Q

4 types if intrinsic feedback

A

proprioception
auditory
touch
visual

31
Q

example of a long interval session

A

60-85% MHR
30+ sec
1:1,2:1

32
Q

venous return

A

amount of blood returning back to the heart via the veins

33
Q

aerobic power

A

max rate of energy produced from 02 system

34
Q

example of intermediate training session

A

3 x 2-8 85-95%MHR 10-30 sec 1:3 1 min rest

35
Q

how does age affect muscular power

A

30+ ↓ Protein synthesis ∴↓ CP storage ∴↓ mm ∴ ability to perform to produce max force quickly

36
Q

4 purposes of EPOC

A
  • replenish CP
    -restore o2 to myoglobin
  • regulate body temp
  • remove H+ions
37
Q

displacement

A

diff in starting Vs finishing point
eg. 100m in 50m pool Disp=0
eg. 3k on a track disp=3km

38
Q

describe blood plasma levels and outline how they respond to exercise

A

blood plasma levels = fluid component of the blood
↓ as a result of sweat ∴↑blood viscosity ∴ harder to pump blood around the body

39
Q

how does the AG syst cause fatigue

A

↑LA ∴↑H+ions→inhibit use of glycogen→↑triglycerides=↓er rate of resynthesis ∴ ↑ muscle acidity → inhibit muscle contractions = fatigue

40
Q

closed skill

A

↓ITV, int paced, predictable environment

41
Q

momentum

A

motion a body possess MxA

42
Q

def musc power

A

ability to create force as quick as possible

43
Q

gross motor skill

A

large muscle groups
↑ed forced ↓ed precision eg. shoulder pass

44
Q

how does sex impact aerobic power

A

males = higher than f
↑ed muscle size→↑mitochondria → ↑ed ability to produce energy 02lly = ↑AP

45
Q

how does speed of muscle contractions increase in response to increased intensity?

A

↑ speed of contraction = ↑ firing rate of motor units

46
Q

advantage and disadvantage of aerobic system

A

adv- no metabolic by products
disadv- 02 req

47
Q

discrete skill

A

clear beginning and end eg. netball pass

48
Q

Conservation of angular momentum

A

same throughout rotation
↑AV=↓MOI
↑MOI=↓AV

49
Q

muscular strength

A

ability to produce peak force in a muscle

50
Q

why does force of muscle contraction increase in response to increase in intensity

A

due to increased motor unit recruitment

51
Q

contraints based coaching

A

decisions made by athlete bw enviro and skill

52
Q

third class lever mech adv

A

<1, ↑ROM ↑angular speed at end of lever

53
Q

sociological factors of fitness testing

A

considerations outside of individual eg. culutre ses acess

54
Q

Rship bw SV HR AND Q

A

Chronic - HR X SV = Q
incr SV @ sun max then plateau decr HR bc more blood pumped out per beat = Q stay the same @ rest and su max

(Q incr at max)

55
Q

Qualitative analysis

A

Info abt technique of skill
Preparation. Observation. Evaluation. Error correction

56
Q

Types of practice distribution

A

Massed - little breaks
Distributed - breaks bw
