Answer 4

its when the muscles changes in the length as they contract

Question 5

Answer 5

concentric contraction: is when the muscle shortens

eccentric contraction: is when the muscle lengthen

Question 6

isometric contraction

Answer 6

when the muscles contract but they stay the same length

Question 7

slow twitch fibres

Answer 7

contract slowly
produces little force
higher fatigue tolerance
good for endurance

Question 8

fast twitch fibres

Answer 8

contract faster
produces more force
lower fatigue tolerance
good for strength and power

Question 9

how to calculate minute ventilation

Answer 9

tidal volume(ml) x number of breaths (per minute)

Question 10

tidal volume

Answer 10

the volume of air inhaled during normal breathing

Question 11

minute ventilation

Answer 11

the volume of air you breathe per minute

Question 12

vital capacity

Answer 12

the maximum volume of air you can breath out

Question 13

residual volume

Answer 13

the volume of air left in your lungs after breathing out

Question 14

stroke volume

Answer 14

the volume of blood ejected from the heart per beat
