Effects of Exercise

Question 1

What happens to the temperature of your muscles when you exercise?

Answer 1

the temperature increases

Question 2

What i produced in the muscles during exercise that results in muscular pain and fatigue?

Answer 2

lactic acid

Question 3

What happens to your heart rate when you exercise?

Answer 3

It gets faster

Question 4

What hormone is released when you start exercising that helps prepare your body for ‘fight or flight’?

Answer 4

adrenaline

Question 5

What is the vascular shunt?

Answer 5

when you exercise, blood vessels going to the digestive system constrict and blood vessels going to the working muscles dilate so more blood and oxygen can go to the working muscles that need oxygen to make energy

Question 6

What is another name for the vascular shunt?

Answer 6

blood shunting

Question 7

What does vasocontriction mean?

Answer 7

blood vessels get smaller

Question 8

what does vasodilation mean?

Answer 8

blood vessels get bigger

Question 9

what happens to your breathing rate when you exercise?

Answer 9

it gets faster

Question 10

what happens to your stroke volume when you exercise?

Answer 10

it increases

Question 11

What happens to your cardiac output when you exercise?

Answer 11

It increases

Question 12

What happens to your tidal volume when you exercise?

Answer 12

It increases

Question 13

What happens to your minute ventilation when you exercise?

Answer 13

it increases

Question 14

How does the muscular system adapt to regular training (long term effects)?

Answer 14

hypertrophy of muscles (they get bigger and stronger)
muscular strength, increases
muscular endurance increases
tendons get stronger

Question 15

How does the skeletal system adapt to regular exercise (long term effects)?

Answer 15

bones become stronger / bone density increases
less risk of osteoporosis
ligaments become stronger and more elastic

Question 16

How does the cardiovascular system adapt to regular training (long term effects)?

Answer 16

hypertrophy of the heart (it gets bigger)
decreased resting heart rate
increased stroke volume
increased cardiac output
quicker recovery time
increased capillarisation of muscles
blood vessels become more efficient with the vascular shunt mechanism
blood pressure decreases
more red blood cells

Question 17

How does the respiratory system adapt to regular training(long term effects)?

Answer 17

increase in capillary density around the alveoli so more efficient oxygen uptake
increase n tidal volume
increase in intercostal muscle strength, allowing more air to be breathed in/out
increased efficiency of gaseous exchange
