Aim: Investigate the effect of a factor on Heart Rate

Introduction: People exercise on a daily basis for a variety of reasons. With exercise people often find themselves short of breath and must breathe deeply and more often in order to compensate. Due to the fact that exercise causes someone to breathe more rapidly, it would also seem that it also increases someone’s heart rate. In order to gauge the effect of exercise on someone’s heart rate, this lab will vary the periods of exercise that one undergoes and heart rate will be recorded afterwards. It would seem that the longer the duration of the exercise, the higher the heart rate will be.

Research Question: Does the duration of exercise have an increased effect on a person’s heart rate?

Independent Variable: The duration of exercise

- Exercise will occur for periods of 0 seconds, 45 seconds and 90 seconds after each heart rate will be recorded

Dependent Variable:  The heart rate of a person in beats per minute

        - Immediately after exercise students will find their pulse on their neck and count the number of beats they feel in a sixty second time period

Control Variable:

-Pulse will be found at one’s neck each time. This is done to avoid confusion when counting pulse and so that in case pulse recorded varies in other parts of the body such as the wrist such error can at least be consistent.

- The Type of exercise will be restricted to Jumping Jack. This is done because different exercises are more taxing than others, by at least each individual will be performing the same degree of activity.

- Each person will record their base-level heart rate by exercising for 0 seconds.

- The Temperature of the room will remain constant by allowing all individuals to exercise in the same room.

Materials:

-Clock

Procedure:

  1. Gather at least 10 students for exercise and 1 other student to watch time
  2. Assign  a Time watcher
  3. Record base-level Heart Rate
  1. Tell the 10 students to find their pulse.
  1. For purposes of consistentcy the pulse area will be the neck
  2. Place two fingers on the center of your chin
  3. Run your two fingers down until you feel your adams apple
  4. Slightly move your two fingers to the right applying pressure
  5. Stop moving fingers once a thumping sensation is felt on fingers

  1. Explain to students that at the count of three they are to count the number of heart beats
  2. Have Time Watcher count aloud to three
  3. On three tell students to record their heart rate
  4. The Time Watcher should count 60 seconds by watching the clock
  5. After 60seconds the Time Watcher should shout “Stop”
  6. Record each students heart rate
  1. Perform Jumping jacks
  1. Rest at least two minutes breathing normally allowing your heart rate to normalize.
  2. Tell the 10 students to spread out with enough space to perform jumping jacks
  3. Tell the students to begin performing ...
