Q

Why is the ATP store used for short sporting movements?

A
  • because ATP breakdown provides energy for immediate need

-ATP breakdown provides energy for very high intensity

Q

Describe the mechanism of vascular shunt?

A

-vasomotor control is used

  • arterioles leading to the working muscles vasodilate
  • Pre capillary sphincters dilate leading to working muscles
  • the arterioles to the organs Vaso constrict to reduce blood flow

-pre capillary sphincters leading to organs constrict

Q

Describe why the tidal volume between a trained athlete is different to an untrained athlete?

A

-trained athlete= more efficient O2 utilisation

-higher red blood cell count

  • fewer breaths per minute to bring more air in

16
Q

Describe the process of treating acute injuries?

A

-P- protection= stop playing and protect player and injury

-R-rest= allow injury to heal and prevent further damage

-I- ice= apply ice indirectly to skin to reduce inflammation

-C-compression= compress the injury with tear tape

-E- elevation= raise the injury above heart leaves to reduce blood flow to area

17
Q

Describe factors which allow gymnast to perform the splits?

A

-warm up- increased temperature of tissue which leads to greater ROM at hips

-greater elasticity of connective tissue= greater ROM at hips

-younger people= greater ROM at hips

18
Q

Describe an adaptation of flexibility training?

A

-increased elasticity of connective muscle tissue

  • reduced inhibition of stretch reflex
19
Q

Describe HITT training?

A

-periods of high intensity work followed by periods of rest

-full sessions last for 20-60 minutes

-exercise= cycling running, star jumps

  • work intensity= 80-90%
20
Q

What’s an advantage of using HITT?

A

Individuals with all different fitness levels can train together as a group

21
Q

Describe how inspiration changes during exercise?

A

-external intercostal contract with more force= volume of thoracic cavity

  • greater decrease in pressure= more air enters lungs
  • sterncleidomastid/ pectoralis minor assist= greater volume= more air in
22
Q

Describe how expiration changes during excercise?

A

-internal intercostals/ rectus abdomins contract= reducing volume of thoracic cavity

-increase in pressure in lungs forcing more air out of the lungs

  • expiration becomes an active process

-greater volume out/ in= greater rate of gas exchange

23
Q

Describe adaptations made by the metabolic system after aerobic training?

A

-increased aerobic enzyme activity= increased metabolism of glycogen

  • reduced fat mass= increased lean mass
24
Q

Describe muscular adaptations made by aerobic training?

A

-muscle hypertrophy of slow oxidative twitch

-increased size of mitochondria= more aerobic energy produced

&

Increased endurance

25
Q

Describe dynamic strength?

A

Force applied with movement

E.g: throwing javelin

26
Q

Describe static strength?

A

Force applied with no force

E.g: crufix ring in gymnastics

27
Q

Describe maximum strength?

A

Greatest force applied in a single contraction

E.g: deadlift

28
Q

Why is flexibility needed for a javelin thrower?

A

So they can gain more distance

29
Q

What are adaptations of flexibility training?

A

-increased ROM= reduced risk of injury- side step in rugby

  • increased elasticity of muscle tissues= stretch reflex is initiated at a greater range of motion

-increased power can be generated= increased stretch/ relaxation of antagonists

  • improved posture= prevent chronic injuries
30
Q

Give structural adaptation of FOG fibres?

A
  • large motor unit- allows large force of contraction

-high capillary density- allows more oxygenated blood to muscles

  • good mitochondrial density- more sites of aerobic respiration
31
Q

What is a structural feature of the fast oxidative fibres?

A

Good resistance to fatigue- high intensity work

= good for game players= football

32
Q

How can injuries be assessed?

A

S- see what happens

A- ask what happened

L- look for swelling

T- touch injures area

A-Active, ask player if they can move the injury

P-passive- move injury through full range of motion

S-strength- ask player to stand and put pressure on injury

33
Q

How can injuries be treated?

A

P- protection- protect injury

R-rest- allow injury to heal

I- apply ice to the injured area ti get rid of swelling

C-compress the injured area

E-elevate injury to prevent blood going to it

34
Q

How do you treat concussions?

A

R-recognise

R- remove

R-refer (hospital)

R-rest

R- recover

R-return

35
Q

Describe intrinsic factors?

A

-previous injury

-posture and alignment issues

-Age

-nutrition

36
Q

Describe extrinsic factors?

A

-Incorrect equipment and clothing

-poor technique and training

  • inappropriate intensity, duration or frequency
