Worksheet time: 10mins
What are the features of fast twitch 2x muscle fibre
low force, high O2 content, long duration
medium force, low O2 content, long duration
max force, No O2 content, no capillaries,
high force, no O2 content, high capillaries
A single muscle stimulation is known as
Twitch
Wave Summation
Tetanus
Type l Fibre
An isometric muscle stimulation that is constant is known as
Twitch
Wave Summation
Tetanus
Type lla
To increase blood flow which vessels have the ability to dilate
Capillaries
Arterioles
Veins
Coronary Artery
An increase in temperature in the muscle also increases select which 2 apply)
someone's ego
range of motion of the muscle
flexibility
height
An increase in muscle temperature is cause by what (PICK TWO)
less blood flow
slower heart rate
contractions
breakdown of ATP
microtears are repaired using
proteins
carbs
fats
calcium
Which muscle fibres are used in this easy exercise
Type l
Type lla
Type llx
none
If breathing doesn’t increase it wont bring enough O2 and will build up CO2 causing a change in
alkaline
blood volume
lower breathing rate
acidic blood pH
which receptors detect a chemical change in the blood
baroreceptors
thermoreceptors
chemoreceptors
velociraptor
any changes in chemicals, pressure, or temperature is reported to the
marbella
medusa
mandella
medulla
When we exhale the diaphragm will
contract and flatten
call a friend
relax and recoil
explode
Exhaling deeper uses internal intercostals, but what about inhaling
external
internal
phenomenol
paracetamol
internal intercostals will only contract when we
breath in deeper
breath out deeper
sleep
watch tv
what other 'additional muscles' help us inhale further than normal
rectus femoris
sternocleidomastoid
trapezius
scalene
Select why muscles ache days after a body pump class (PICK THREE)
DOMS (delayed onset of muscle soreness)
bones were too warm
didnt try hard enough
overloaded (worked harder than capable)
microtears
A change in breathing rate is caused by...
increased O2 in the blood stream
higher pH in blood stream
lower temperature in the muscle
increase CO2 in the bloodstream
how is breathing rate controlled (select 4)
detection of high CO2 in blood by baroreceptors
signals are sent to SA node in the heart
detection of high CO2 in blood by chemoreceptors
signal sent to Respiratory Control Centre (RCC/Medulla)
RCC signals breathing muscles to contract
how does tidal volume alter in exercise (pick 2)
breath in and out deeper
breath slower
take short breaths
breath faster
When we inspire further, which muscle is needed and what does it help do
lower the diaphragm
depress and lower the rib cage
lift and open the rib cage to draw more air in
rectus abdominus
sternocleidomastoid
When we exhale further, which muscle is needed and what does it help do
rectus abdominus
squeezes the lungs to squeeze air out
lift and open the rib cage
depress and lower the rib cage
scalene
What is Pedro's minute volume during his 5km run - breathing rate = 30... Tidal Volume = 2 litres
6 litres
60 litres
20 litres
30 litres
