what does IRV stand for and what does it mean
Inspiratory Reserve volume-the extra amount of air you can forcibly breathe in after a normal inhalation
what does ERV stand for and what does it mean
Expiratory Reserve Volume-he extra amount of air you can forcefully breathe out after a normal, resting breath
what is residual volume
amount of air left in lungs after fully breathing out
what is tidal volume
amount of air entering or leaving lungs during normal inspiration
what happens when you breathe in(diaphragm,muscles)
-diaphragm contracts and flattens
-ribs and intercostal muscles contract
-air pressure moves from high pressure outside to low pressure inside
what happens when you breathe out
-Diaphragm relaxes and goes into a dome shape
-Ribs and intercostal muscles relax
-air pressure moves from high pressure inside to low pressure outside
Explain how muscles and bones work together to create movement
the antagonist muscle relaxes(longer)
the agonist muscle contracts(shorter)
these antagonistic muscles work together to create movement
tendons attach muscle to bone
what is stroke volume
the amount of blood pumped out of the left ventricle per heart beat
what is EPOC and what does it do
Excessive Post Oxygen Consumption-helps removal of lactic acid
what are the 8 movements of the joints
flexion
extension
adduction
abduction
circumduction
rotation
plantar flexion
dorsi-flexion
what is vasodilation
when blood vessels get bigger for more blood to the muscles
what is vasoconstriction
blood vessels getting smaller to decrease the amounts of blood going to the organs
fartleg training is
stuff like walking,running(cardio)
what muscles help with inspiration
the pectorals and sternacleidomasteoid
what muscles help with expiration
the abdominals
what is cardiac output
is the amount of blood that the heart can pump out per minute
what are the immediate effects of exercise
-increase of heart rate
-stroke volume will increase
-breathing rate increases, depth of breath
what are the short terms of exercise(24-36 hours after)
-tiredness and fatigue
-light headedness
-nausea
-cramps
what are the long term effects of exercise(6 months or years)
-body shape can change
-increase of muscle mass
-stronger
-lower body fat
-hypertrophy
