Activity 2 Today at each fitness station, see how many times and how long you can keep moving.
Joints flex.
Aerobic Capacity (AC) I can maintain continuous activity for a specified time using oxygen.

AC and ME Aerobic Capacity- (AC) ability of your heart and lungs to use oxygen Muscle Endurance (ME)- how long can you exercise?
O-2 Me-2 The oxygen tag game muscles need 0-2 Once you are tagged by carbon dioxide, freeze and get 5 breaths. The blue dot is the oxygen station.

Activity 2 At today’s stations: the dome run will be a great test to measure effort and AC. Your bodies will be require more oxygen during activity. The faster you go, the more oxygen you will need (V-02). As soon as you slow down or stop: Pass the Baton.
