Answer 22

02 from alveoli to blood
c02 from blood to lungs

Question 23

inertia

Answer 23

resist of a body to change its state of motion

Question 24

age affecting aerobic power

Answer 24

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

Question 25

what do movement patterns determine ??

Answer 25

FC And ES

Question 26

2 benefits of continuous training

Answer 26

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

Question 27

how does muscle fibre type affect musc strength ??

Answer 27

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

Question 28

what does AVO2 diff give an indication of??

Answer 28

how much o2 muscles use

Question 29

describe fartlek training

Answer 29

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

Question 30

4 types if intrinsic feedback

Answer 30

proprioception auditory touch visual
