Procedure: You (or a friend or family member) will exercise for 8 minutes by skipping in place. Physical parameters will be recorded at rest, 2 minutes, 4 minutes, 6 minutes and 8 minutes, and 1 minute after exercise has stopped. The subject should stop just long enough for the needed measurements to be taken. Record all data in a table. Materials: a thermometer and a timer A. Record the RESTING observations and values of your subject for each of the 3 parameters in a table. 1. Record external body temperature by placing the thermometer under the subjects arm pit for one minute (note: measurements should be taken directly from the skin). 2. Determine the breathing rate by counting the number of breaths taken in 10 seconds and multiply by 6. 3. Determine the heart rate by counting the number of breaths taken in 10 seconds and multiply by 6. B. Have your subject begin to skip in place. Please note your subject should be sure to exercise at a level they can maintain for the entire 8 minutes. 1. Take your subjects parameter readings using the same techniques described above at the 2, 4, 6, and 8 minute time markers
