Short Term Effects of Exercise 1 Flashcards
(11 cards)
what do your muscles release when you exercise
extra energy for movement which generates heat so you feel hot and sweaty
what do your muscles produce during anaerobic exercise
lactic acid which can build up to make your muscles painful and cause muscle fatigue
what do muscles need to do if they are fatigued
they need oxygen to remove the lactic acid and recover
what is the amount of oxygen you need to remove the lactic acid
oxygen debt or excess post-exercise oxygen consumption (EPOC)
what are short (24-36 hours) term effects of exercise
feeling sick, light-headed, DOMS or tiredness after using energy
what muscles expand your lungs to let in extra air
the pectorals and the sternocleidomastoid
what do muscles in the abdomen do
they work to pull your ribcage down and shrink the chest cavity quicker, so you breathe out faster
how do short-term effects on the respiratory system impact your breathing
your breathing depth and your tidal volume increase whilst the rate of breathing also increases
how do you meet the increased demand for oxygen in the muscles during exercise
more oxygen is taken in and transferred to the blood so you can do aerobic exercise for long periods of time
what happens to your breathing during anaerobic exercise
your breathing rate and depth will remain higher than normal until you’ve taken in enough oxygen to repay the oxygen debt
how does intense exercise affect the changes in the respiratory system
you’ll breathe deeper and quicker when exercising hard than when doing light exercise
