How Exercise Affects Heart Rates

Teacher’s Instructions: Design a lab to show the effect of exercise on one parameter of your body.

AIM: 

To see how different types exercises cause different heart rates.

BACKGROUND:

When a person exercises, they start respiring differently, greater amount of blood is pumped into their heart, which causes a significant increase in their heart rate. Through this experiment one will see how exercise affects heart rate.

HYPOTHESIS:

 

The more rigorous the exercise, the more energy will be consumed by the body. Thus, the heart will beat faster as the intensity of the exercise increases.

VARIABLES:

-INDEPENDENT VARIABLE- The different types of exercises,

  • Running up a flight of stairs for a minute
  • Skipping for a minute
  • Walking on a treadmill for a minute
  • Lifting weights of 15kgs in each hand for a minute

-DEPENDENT VARIABLE- Different heart rates

-CONTROLLED VARIABLE-

  • The time spent (i.e.: one minute on each exercise)
  • The atmosphere and temperature should be the same for all exercises
  • The subject’s pulse rate should return to normal before another exercise

APPARATUS: To conduct the exercises we require,

  1. A flight of stairs ...
