Resp rate at rest=_____
Resp rate at exercise= _____ |
12-20 BPM
up to 180 BPM |
|
|
_____= coupled to stride at canter and gallop, 1:1 breath to stride ratio
|
locomotor-respiratory coupling
|
|
|
____= amt of air inhaled with each breath, 4-7 L at rest
during exercise, max is 10 L |
tidal volume
|
|
|
____= tidal volume minus dead space
- small during rest -greatly expanded during exercise |
alveolar volume
|
|
|
____= resp rate multiplied by tidal volume
-rest = 100L/min -max exercise= 1500L/min |
minute volume
|
|
|
effects of exercise conditioning on resp system;
*** resp tract is the weak link in the oxygen supply pathway |
chemoreceptors in blood vessels, sense changes in O2 and CO2 pressure and pH
-stimulates resp muscles and respiration -conditioning improves muscle that holds the airways open (nostrils,pharynx.larynx) - lower resp tract- minimal adaptations |
