2.  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.

3. The body quickly becomes
oxygen deficient during the
anaerobic phase and requires
oxygen from the lungs to
maintain its activity.

4.  Take a short walk around the block
 Rake leaves
 Play actively with the kids
 Walk up the stairs instead of taking
the elevator
 Mow the lawn
 Take an activity break--get up and
stretch or walk around
 Park your car a little farther away from
your destination

5.  Brisk walking
 Jogging
 Bicycling
 Swimming
 Aerobic dancing
 Racket sports
 Rowing
 Ice or roller-skating
 Cross-country or downhill skiing
 Using aerobic equipment (i.e., treadmill, stationary
bike)

6.  Actions that initiate the anaerobic
phase are e accommpanied by other
actions that make possible the long-
term production of energy in the
aerobic phase.

7.  Sweat production to dissipate
thermal energy.
 Rapid breathing.
 Dilation of air passageways.

8.  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
activites?

9. 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
