Effects of Exercise Flashcards
What happens to the temperature of your muscles when you exercise?
the temperature increases
What i produced in the muscles during exercise that results in muscular pain and fatigue?
lactic acid
What happens to your heart rate when you exercise?
It gets faster
What hormone is released when you start exercising that helps prepare your body for ‘fight or flight’?
adrenaline
What is the vascular shunt?
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
What is another name for the vascular shunt?
blood shunting
What does vasocontriction mean?
blood vessels get smaller
what does vasodilation mean?
blood vessels get bigger
what happens to your breathing rate when you exercise?
it gets faster
what happens to your stroke volume when you exercise?
it increases
What happens to your cardiac output when you exercise?
It increases
What happens to your tidal volume when you exercise?
It increases
What happens to your minute ventilation when you exercise?
it increases
How does the muscular system adapt to regular training (long term effects)?
hypertrophy of muscles (they get bigger and stronger)
muscular strength, increases
muscular endurance increases
tendons get stronger
How does the skeletal system adapt to regular exercise (long term effects)?
bones become stronger / bone density increases
less risk of osteoporosis
ligaments become stronger and more elastic
How does the cardiovascular system adapt to regular training (long term effects)?
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
How does the respiratory system adapt to regular training(long term effects)?
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
