short term effects of exercise

Question 1

what are the short term effects on the muscular system

Answer 1

• release extra energy for movement which generates heat
• sick or light headed
• tired
• delayed muscle soreness

Question 2

how does your body reduce lactic acid

Answer 2

lactic acid builds up during anaerobic exercise, causing lactate accumulation
this causes pain and muscle fatigue
the muscles need oxygen to remove lactic acid, the amount of oxygen they need is oxygen debt,
to repay oxygen debt, you will need to reduce exercise e.g. periods of rest or low intensity work

Question 3

what is EPOC

Answer 3

excess post exercise oxygen production

Question 4

what are short term effects on respiratory system

Answer 4

increased breathing rate
increased depth of inhalation
increased tidal volume

Question 5

what are short term effects on cardiovascular system

Answer 5

increase in heart rate and stroke volume
increased blood pressure
increased removal of carbon dioxide

Question 6

what is stroke volume

Answer 6

amount of blood each ventricle pumps with each contraction

Question 7

what is cardiac output

Answer 7

heart rate x stroke volume (volume of blood pumped per minute)

Question 8

how do your blood vessels change during exercise

Answer 8

arteries widen to reduce blood pressure
and to move blood transport to primarily the muscles
arterioles vasodilate to let in more blood
blood moves closer to skin to reduce heat by sweat

Question 9

what happens as a result of increase oxygen delivery

Answer 9

breathing rate and depth increase
cardiac output increases so blood passes through the lungs at a faster rate

Question 10

what happens as a result of increased carbon dioxide removal

Answer 10

increased cardiac output means more carbon dioxide is transported to lungs from muscles
gas exchange is faster due to increased breathing and depth rate
