6 anaerobic and aerobic phases final 1Presentation Transcript
Action utilize oxygen already in the
body , and the higher power output
cannot last more than about time.
Anaerobic phase becauase no
ingestion of oxygen is required.
The body quickly becomes
oxygen deficient during the
anaerobic phase and requires
oxygen from the lungs to
maintain its activity.
Take a short walk around the block
Play actively with the kids
Walk up the stairs instead of taking
Mow the lawn
Take an activity break--get up and
stretch or walk around
Park your car a little farther away from
Actions that initiate the anaerobic
phase are e accommpanied by other
actions that make possible the long-
term production of energy in the
Sweat production to dissipate
Dilation of air passageways.
Compare the amount of oxygen
consumed in 1 hour by a cyclist
traveling at 21 km/hr with that used
by a person sleeping .What would
you expect the ratio of the
respiratory rates to be in these two
Rate of oxygen (O2) consumption when cycling
Lo2 =( 2.0 liters O2/min)(60 min)
= 120 liters O2 cycling
And for sleeping
Lo2 = (0.24 liter O2/ min)(60min)
= 14 .4 liters O2 sleeping
The ratio is
120 liters O2 =8.33
14.4 liters O2
