Pulse Rate Further Investigation

  • Investigate your pulse rate while your hand is submerged in cold water. Compare the response over varying amounts of submersion time. Compare the submersion rate compared to your rates during rest and exercise.

  • Complete a long-term study to improve your physical fitness. Interview your health teacher, biology teacher, or personal physician to find out the exercises that help to improve cardiovascular circulation. Design and perform a daily exercise program for one month. If you have any physical restrictions, contact your personal physician to approve your plan. Record and compare your heart rate after exercise each day. Did your heart rate decrease after exercise as the month progressed?
